    Specified by:
    
    getMainLooper in class Context
  - getApplicationContext
```
public Context getApplicationContext()
```
    Description copied from class: Context
    Return the context of the single, global Application object of the current process. This generally should only be used if you need a Context whose lifecycle is separate from the current context, that is tied to the lifetime of the process rather than the current component.
    Consider for example how this interacts with Context.registerReceiver(BroadcastReceiver, IntentFilter):
    - If used from an Activity context, the receiver is being registered within that activity. This means that you are expected to unregister before the activity is done being destroyed; in fact if you do not do so, the framework will clean up your leaked registration as it removes the activity and log an error. Thus, if you use the Activity context to register a receiver that is static (global to the process, not associated with an Activity instance) then that registration will be removed on you at whatever point the activity you used is destroyed.
    - If used from the Context returned here, the receiver is being registered with the global state associated with your application. Thus it will never be unregistered for you. This is necessary if the receiver is associated with static data, not a particular component. However using the ApplicationContext elsewhere can easily lead to serious leaks if you forget to unregister, unbind, etc.

  - getExternalFilesDir
```
public File getExternalFilesDir(String type)
```
    Description copied from class: Context
    Returns the absolute path to the directory on the external filesystem (that is somewhere on Environment.getExternalStorageDirectory()) where the application can place persistent files it owns. These files are private to the applications, and not typically visible to the user as media.
    This is like Context.getFilesDir() in that these files will be deleted when the application is uninstalled, however there are some important differences:
    - External files are not always available: they will disappear if the user mounts the external storage on a computer or removes it. See the APIs on Environment for information in the storage state.
    - There is no security enforced with these files. All applications can read and write files placed here.
    On devices with multiple users (as described by UserManager), each user has their own isolated external storage. Applications only have access to the external storage for the user they're running as.
    
    Here is an example of typical code to manipulate a file in an application's private storage:
    
    If you supply a non-null type to this function, the returned file will be a path to a sub-directory of the given type. Though these files are not automatically scanned by the media scanner, you can explicitly add them to the media database with MediaScannerConnection.scanFile. Note that this is not the same as Environment.getExternalStoragePublicDirectory(), which provides directories of media shared by all applications. The directories returned here are owned by the application, and their contents will be removed when the application is uninstalled. Unlike Environment.getExternalStoragePublicDirectory(), the directory returned here will be automatically created for you.
    Here is an example of typical code to manipulate a picture in an application's private storage and add it to the media database:
    
    Writing to this path requires the android.Manifest.permission#WRITE_EXTERNAL_STORAGE permission.
    Specified by:
    
    getExternalFilesDir in class Context
    
    Parameters:
    type - The type of files directory to return. May be null for the root of the files directory or one of the following Environment constants for a subdirectory: Environment.DIRECTORY_MUSIC, Environment.DIRECTORY_PODCASTS, Environment.DIRECTORY_RINGTONES, Environment.DIRECTORY_ALARMS, Environment.DIRECTORY_NOTIFICATIONS, Environment.DIRECTORY_PICTURES, or Environment.DIRECTORY_MOVIES.
    
    Returns:
    Returns the path of the directory holding application files on external storage. Returns null if external storage is not currently mounted so it could not ensure the path exists; you will need to call this method again when it is available.
    See Also:
    Context.getFilesDir(), Environment.getExternalStoragePublicDirectory(java.lang.String)
  - getObbDir
```
public File getObbDir()
```
    Description copied from class: Context
    
    Return the directory where this application's OBB files (if there are any) can be found. Note if the application does not have any OBB files, this directory may not exist.
    On devices with multiple users (as described by UserManager), multiple users may share the same OBB storage location. Applications should ensure that multiple instances running under different users don't interfere with each other.
    
    Specified by:
    
    getObbDir in class Context
  - getCacheDir
```
public File getCacheDir()
```
    Description copied from class: Context
    
    Returns the absolute path to the application specific cache directory on the filesystem. These files will be ones that get deleted first when the device runs low on storage. There is no guarantee when these files will be deleted. Note: you should not rely on the system deleting these files for you; you should always have a reasonable maximum, such as 1 MB, for the amount of space you consume with cache files, and prune those files when exceeding that space.
    
    Specified by:
    
    getCacheDir in class Context
    
    Returns:
    Returns the path of the directory holding application cache files.

    Context.openFileOutput(java.lang.String, int), Context.getFileStreamPath(java.lang.String), Context.getDir(java.lang.String, int)
  - getExternalCacheDir
```
public File getExternalCacheDir()
```
    Description copied from class: Context
    Returns the absolute path to the directory on the external filesystem (that is somewhere on Environment.getExternalStorageDirectory() where the application can place cache files it owns.
    This is like Context.getCacheDir() in that these files will be deleted when the application is uninstalled, however there are some important differences:
    - The platform does not always monitor the space available in external storage, and thus may not automatically delete these files. Currently the only time files here will be deleted by the platform is when running on Build.VERSION_CODES.JELLY_BEAN_MR1 or later and Environment.isExternalStorageEmulated() returns true. Note that you should be managing the maximum space you will use for these anyway, just like with Context.getCacheDir().
    - External files are not always available: they will disappear if the user mounts the external storage on a computer or removes it. See the APIs on Environment for information in the storage state.
    - There is no security enforced with these files. All applications can read and write files placed here.
    On devices with multiple users (as described by UserManager), each user has their own isolated external storage. Applications only have access to the external storage for the user they're running as.
    
    Writing to this path requires the android.Manifest.permission#WRITE_EXTERNAL_STORAGE permission.
    Specified by:
    
    getExternalCacheDir in class Context
    
    Returns:
    Returns the path of the directory holding application cache files on external storage. Returns null if external storage is not currently mounted so it could not ensure the path exists; you will need to call this method again when it is available.

    Context.getCacheDir()
  - getDir
```
public File getDir(String name,
          int mode)
```
    Description copied from class: Context
    
    Retrieve, creating if needed, a new directory in which the application can place its own custom data files. You can use the returned File object to create and access files in this directory. Note that files created through a File object will only be accessible by your own application; you can only set the mode of the entire directory, not of individual files.
    
    Specified by:
    
    getDir in class Context
    
    Parameters:
    name - Name of the directory to retrieve. This is a directory that is created as part of your application data.
    mode - Operating mode. Use 0 or Context.MODE_PRIVATE for the default operation, Context.MODE_WORLD_READABLE and Context.MODE_WORLD_WRITEABLE to control permissions.
    
    Returns:
    Returns a File object for the requested directory. The directory will have been created if it does not already exist.

  - startActivityAsUser
```
public void startActivityAsUser(Intent intent,
                       UserHandle user)
```
    Description copied from class: Context
    
    Version of Context.startActivity(Intent) that allows you to specify the user the activity will be started for. This is not available to applications that are not pre-installed on the system image. Using it requires holding the INTERACT_ACROSS_USERS_FULL permission.
    
    Overrides:
    
    startActivityAsUser in class Context
    
    Parameters:
    intent - The description of the activity to start.
    user - The UserHandle of the user to start this activity for.
  - startActivity
```
public void startActivity(Intent intent,
                 Bundle options)
```
    Description copied from class: Context
    
    Launch a new activity. You will not receive any information about when the activity exits.
    Note that if this method is being called from outside of an Activity Context, then the Intent must include the Intent.FLAG_ACTIVITY_NEW_TASK launch flag. This is because, without being started from an existing Activity, there is no existing task in which to place the new activity and thus it needs to be placed in its own separate task.
    This method throws ActivityNotFoundException if there was no Activity found to run the given Intent.
    
    Specified by:
    
    startActivity in class Context
    
    Parameters:
    intent - The description of the activity to start.
    options - Additional options for how the Activity should be started. May be null if there are no options. See ActivityOptions for how to build the Bundle supplied here; there are no supported definitions for building it manually.

                       UserHandle user)
```
    Description copied from class: Context
    
    Version of Context.startActivity(Intent, Bundle) that allows you to specify the user the activity will be started for. This is not available to applications that are not pre-installed on the system image. Using it requires holding the INTERACT_ACROSS_USERS_FULL permission.
    
    Overrides:
    
    startActivityAsUser in class Context
    
    Parameters:
    intent - The description of the activity to start.
    options - Additional options for how the Activity should be started. May be null if there are no options. See ActivityOptions for how to build the Bundle supplied here; there are no supported definitions for building it manually.
  - startActivities

public void startActivities(Intent[] intents)
```
    Description copied from class: Context
    
    Same as Context.startActivities(Intent[], Bundle) with no options specified.
    
    Specified by:
    
    startActivities in class Context
    
    Parameters:
    intents - An array of Intents to be started.
    See Also:
    #startActivities(Intent[], Bundle)}, PackageManager.resolveActivity(android.content.Intent, int)
  - startActivities
```
public void startActivities(Intent[] intents,
                   Bundle options)
```
    Description copied from class: Context
    
    Launch multiple new activities. This is generally the same as calling Context.startActivity(Intent) for the first Intent in the array, that activity during its creation calling Context.startActivity(Intent) for the second entry, etc. Note that unlike that approach, generally none of the activities except the last in the array will be created at this point, but rather will be created when the user first visits them (due to pressing back from the activity on top).
    This method throws ActivityNotFoundException if there was no Activity found for any given Intent. In this case the state of the activity stack is undefined (some Intents in the list may be on it, some not), so you probably want to avoid such situations.
    
    Specified by:
    
    startActivities in class Context
    
    Parameters:
    intents - An array of Intents to be started.
    options - Additional options for how the Activity should be started. See Context.startActivity(Intent, Bundle) for more details.

```
    Description copied from class: Context
    
    Like Context.startActivity(Intent, Bundle), but taking a IntentSender to start. If the IntentSender is for an activity, that activity will be started as if you had called the regular Context.startActivity(Intent) here; otherwise, its associated action will be executed (such as sending a broadcast) as if you had called IntentSender.sendIntent on it.
    
    Specified by:
    
    startIntentSender in class Context
    
    Parameters:
    intent - The IntentSender to launch.
    fillInIntent - If non-null, this will be provided as the intent parameter to IntentSender.sendIntent(android.content.Context, int, android.content.Intent, android.content.IntentSender.OnFinished, android.os.Handler).
    flagsMask - Intent flags in the original IntentSender that you would like to change.
    flagsValues - Desired values for any bits set in flagsMask
    extraFlags - Always set to 0.
    options - Additional options for how the Activity should be started. See Context.startActivity(Intent, Bundle) for more details. If options have also been supplied by the IntentSender, options given here will override any that conflict with those given by the IntentSender.

```
    Description copied from class: Context
    
    Version of Context.sendBroadcast(Intent) that allows you to receive data back from the broadcast. This is accomplished by supplying your own BroadcastReceiver when calling, which will be treated as a final receiver at the end of the broadcast -- its BroadcastReceiver.onReceive(android.content.Context, android.content.Intent) method will be called with the result values collected from the other receivers. The broadcast will be serialized in the same way as calling Context.sendOrderedBroadcast(Intent, String).
    Like Context.sendBroadcast(Intent), this method is asynchronous; it will return before resultReceiver.onReceive() is called.
    See BroadcastReceiver for more information on Intent broadcasts.
    
    Specified by:
    
    sendOrderedBroadcast in class Context
    
    Parameters:
    intent - The Intent to broadcast; all receivers matching this Intent will receive the broadcast.
    receiverPermission - String naming a permissions that a receiver must hold in order to receive your broadcast. If null, no permission is required.
    resultReceiver - Your own BroadcastReceiver to treat as the final receiver of the broadcast.
    scheduler - A custom Handler with which to schedule the resultReceiver callback; if null it will be scheduled in the Context's main thread.
    initialCode - An initial value for the result code. Often Activity.RESULT_OK.
    initialData - An initial value for the result data. Often null.
    initialExtras - An initial value for the result extras. Often null.

    Version of Context.sendOrderedBroadcast(Intent, String, BroadcastReceiver, Handler, int, String, Bundle) that allows you to specify the user the broadcast will be sent to. This is not available to applications that are not pre-installed on the system image. Using it requires holding the INTERACT_ACROSS_USERS permission.
    See BroadcastReceiver for more information on Intent broadcasts.
    
    Specified by:
    
    sendOrderedBroadcastAsUser in class Context
    
    Parameters:
    intent - The Intent to broadcast; all receivers matching this Intent will receive the broadcast.
    user - UserHandle to send the intent to.
    receiverPermission - String naming a permissions that a receiver must hold in order to receive your broadcast. If null, no permission is required.
    resultReceiver - Your own BroadcastReceiver to treat as the final receiver of the broadcast.
    scheduler - A custom Handler with which to schedule the resultReceiver callback; if null it will be scheduled in the Context's main thread.
    initialCode - An initial value for the result code. Often Activity.RESULT_OK.
    initialData - An initial value for the result data. Often null.
    initialExtras - An initial value for the result extras. Often null.

  - sendStickyBroadcast
```
public void sendStickyBroadcast(Intent intent)
```
    Description copied from class: Context
    
    Perform a Context.sendBroadcast(Intent) that is "sticky," meaning the Intent you are sending stays around after the broadcast is complete, so that others can quickly retrieve that data through the return value of Context.registerReceiver(BroadcastReceiver, IntentFilter). In all other ways, this behaves the same as Context.sendBroadcast(Intent).
    You must hold the android.Manifest.permission#BROADCAST_STICKY permission in order to use this API. If you do not hold that permission, SecurityException will be thrown.
    
    Specified by:
    
    sendStickyBroadcast in class Context
    
    Parameters:
    intent - The Intent to broadcast; all receivers matching this Intent will receive the broadcast, and the Intent will be held to be re-broadcast to future receivers.

                              Bundle initialExtras)
```
    Description copied from class: Context
    
    Version of Context.sendStickyBroadcast(android.content.Intent) that allows you to receive data back from the broadcast. This is accomplished by supplying your own BroadcastReceiver when calling, which will be treated as a final receiver at the end of the broadcast -- its BroadcastReceiver.onReceive(android.content.Context, android.content.Intent) method will be called with the result values collected from the other receivers. The broadcast will be serialized in the same way as calling Context.sendOrderedBroadcast(Intent, String).
    Like Context.sendBroadcast(Intent), this method is asynchronous; it will return before resultReceiver.onReceive() is called. Note that the sticky data stored is only the data you initially supply to the broadcast, not the result of any changes made by the receivers.
    See BroadcastReceiver for more information on Intent broadcasts.
    
    Specified by:
    
    sendStickyOrderedBroadcast in class Context
    
    Parameters:
    intent - The Intent to broadcast; all receivers matching this Intent will receive the broadcast.
    resultReceiver - Your own BroadcastReceiver to treat as the final receiver of the broadcast.
    scheduler - A custom Handler with which to schedule the resultReceiver callback; if null it will be scheduled in the Context's main thread.
    initialCode - An initial value for the result code. Often Activity.RESULT_OK.
    initialData - An initial value for the result data. Often null.
    initialExtras - An initial value for the result extras. Often null.

  - registerReceiver
```
public Intent registerReceiver(BroadcastReceiver receiver,
                      IntentFilter filter)
```
    Description copied from class: Context
    
    Register a BroadcastReceiver to be run in the main activity thread. The receiver will be called with any broadcast Intent that matches filter, in the main application thread.
    The system may broadcast Intents that are "sticky" -- these stay around after the broadcast as finished, to be sent to any later registrations. If your IntentFilter matches one of these sticky Intents, that Intent will be returned by this function and sent to your receiver as if it had just been broadcast.
    There may be multiple sticky Intents that match filter, in which case each of these will be sent to receiver. In this case, only one of these can be returned directly by the function; which of these that is returned is arbitrarily decided by the system.
    If you know the Intent your are registering for is sticky, you can supply null for your receiver. In this case, no receiver is registered -- the function simply returns the sticky Intent that matches filter. In the case of multiple matches, the same rules as described above apply.
    See BroadcastReceiver for more information on Intent broadcasts.
    As of Build.VERSION_CODES.ICE_CREAM_SANDWICH, receivers registered with this method will correctly respect the Intent.setPackage(String) specified for an Intent being broadcast. Prior to that, it would be ignored and delivered to all matching registered receivers. Be careful if using this for security.
    
    Note: this method cannot be called from a BroadcastReceiver component; that is, from a BroadcastReceiver that is declared in an application's manifest. It is okay, however, to call this method from another BroadcastReceiver that has itself been registered at run time with Context.registerReceiver(android.content.BroadcastReceiver, android.content.IntentFilter), since the lifetime of such a registered BroadcastReceiver is tied to the object that registered it.
    
    Specified by:
    
    registerReceiver in class Context
    
    Parameters:
    receiver - The BroadcastReceiver to handle the broadcast.
    filter - Selects the Intent broadcasts to be received.
    
    Returns:
    The first sticky intent found that matches filter, or null if there are none.

public void unregisterReceiver(BroadcastReceiver receiver)
```
    Description copied from class: Context
    
    Unregister a previously registered BroadcastReceiver. All filters that have been registered for this BroadcastReceiver will be removed.
    
    Specified by:

  - startService
```
public ComponentName startService(Intent service)
```
    Description copied from class: Context
    
    Request that a given application service be started. The Intent can either contain the complete class name of a specific service implementation to start, or an abstract definition through the action and other fields of the kind of service to start. If this service is not already running, it will be instantiated and started (creating a process for it if needed); if it is running then it remains running.
    Every call to this method will result in a corresponding call to the target service's Service.onStartCommand(android.content.Intent, int, int) method, with the intent given here. This provides a convenient way to submit jobs to a service without having to bind and call on to its interface.
    Using startService() overrides the default service lifetime that is managed by Context.bindService(android.content.Intent, android.content.ServiceConnection, int): it requires the service to remain running until Context.stopService(android.content.Intent) is called, regardless of whether any clients are connected to it. Note that calls to startService() are not nesting: no matter how many times you call startService(), a single call to Context.stopService(android.content.Intent) will stop it.
    The system attempts to keep running services around as much as possible. The only time they should be stopped is if the current foreground application is using so many resources that the service needs to be killed. If any errors happen in the service's process, it will automatically be restarted.
    This function will throw SecurityException if you do not have permission to start the given service.
    
    Specified by:
    
    startService in class Context
    
    Parameters:
    service - Identifies the service to be started. The Intent may specify either an explicit component name to start, or a logical description (action, category, etc) to match an IntentFilter published by a service. Additional values may be included in the Intent extras to supply arguments along with this specific start call.
    
    Returns:
    If the service is being started or is already running, the ComponentName of the actual service that was started is returned; else if the service does not exist null is returned.
    See Also:
    Context.stopService(android.content.Intent), Context.bindService(android.content.Intent, android.content.ServiceConnection, int)
  - stopService
```
public boolean stopService(Intent name)
```
    Description copied from class: Context
    
    Request that a given application service be stopped. If the service is not running, nothing happens. Otherwise it is stopped. Note that calls to startService() are not counted -- this stops the service no matter how many times it was started.
    Note that if a stopped service still has ServiceConnection objects bound to it with the Context.BIND_AUTO_CREATE set, it will not be destroyed until all of these bindings are removed. See the Service documentation for more details on a service's lifecycle.
    This function will throw SecurityException if you do not have permission to stop the given service.
    
    Specified by:
    
    stopService in class Context
    
    Parameters:
    name - Description of the service to be stopped. The Intent may specify either an explicit component name to start, or a logical description (action, category, etc) to match an IntentFilter published by a service.
    
    Returns:
    If there is a service matching the given Intent that is already running, then it is stopped and true is returned; else false is returned.

  - bindService
```
public boolean bindService(Intent service,
                  ServiceConnection conn,
                  int flags)
```
    Description copied from class: Context
    
    Connect to an application service, creating it if needed. This defines a dependency between your application and the service. The given conn will receive the service object when it is created and be told if it dies and restarts. The service will be considered required by the system only for as long as the calling context exists. For example, if this Context is an Activity that is stopped, the service will not be required to continue running until the Activity is resumed.
    This function will throw SecurityException if you do not have permission to bind to the given service.
    Note: this method can not be called from a BroadcastReceiver component. A pattern you can use to communicate from a BroadcastReceiver to a Service is to call Context.startService(android.content.Intent) with the arguments containing the command to be sent, with the service calling its Service.stopSelf(int) method when done executing that command. See the API demo App/Service/Service Start Arguments Controller for an illustration of this. It is okay, however, to use this method from a BroadcastReceiver that has been registered with Context.registerReceiver(android.content.BroadcastReceiver, android.content.IntentFilter), since the lifetime of this BroadcastReceiver is tied to another object (the one that registered it).
    
    Specified by:
    
    bindService in class Context
    
    Parameters:
    service - Identifies the service to connect to. The Intent may specify either an explicit component name, or a logical description (action, category, etc) to match an IntentFilter published by a service.
    conn - Receives information as the service is started and stopped. This must be a valid ServiceConnection object; it must not be null.
    flags - Operation options for the binding. May be 0, Context.BIND_AUTO_CREATE, Context.BIND_DEBUG_UNBIND, Context.BIND_NOT_FOREGROUND, Context.BIND_ABOVE_CLIENT, Context.BIND_ALLOW_OOM_MANAGEMENT, or Context.BIND_WAIVE_PRIORITY.
    
    Returns:
    If you have successfully bound to the service, true is returned; false is returned if the connection is not made so you will not receive the service object.

    Specified by:
    
    unbindService in class Context
    
    Parameters:
    conn - The connection interface previously supplied to bindService(). This parameter must not be null.

  - startInstrumentation
```
public boolean startInstrumentation(ComponentName className,
                           String profileFile,
                           Bundle arguments)
```
    Description copied from class: Context
    
    Start executing an Instrumentation class. The given Instrumentation component will be run by killing its target application (if currently running), starting the target process, instantiating the instrumentation component, and then letting it drive the application.
    This function is not synchronous -- it returns as soon as the instrumentation has started and while it is running.
    Instrumentation is normally only allowed to run against a package that is either unsigned or signed with a signature that the the instrumentation package is also signed with (ensuring the target trusts the instrumentation).
    
    Specified by:
    
    startInstrumentation in class Context
    
    Parameters:
    className - Name of the Instrumentation component to be run.
    profileFile - Optional path to write profiling data as the instrumentation runs, or null for no profiling.
    arguments - Additional optional arguments to pass to the instrumentation, or null.
    
    Returns:
    Returns true if the instrumentation was successfully started, else false if it could not be found.

    Description copied from class: Context
    
    Determine whether the calling process of an IPC you are handling has been granted a particular permission. This is basically the same as calling Context.checkPermission(String, int, int) with the pid and uid returned by Binder.getCallingPid() and Binder.getCallingUid(). One important difference is that if you are not currently processing an IPC, this function will always fail. This is done to protect against accidentally leaking permissions; you can use Context.checkCallingOrSelfPermission(java.lang.String) to avoid this protection.
    
    Specified by:
    
    checkCallingPermission in class Context
    
    Parameters:
    permission - The name of the permission being checked.
    
    Returns:
    Returns PackageManager.PERMISSION_GRANTED if the calling pid/uid is allowed that permission, or PackageManager.PERMISSION_DENIED if it is not.

    Description copied from class: Context
    
    If the calling process of an IPC you are handling has not been granted a particular permission, throw a SecurityException. This is basically the same as calling Context.enforcePermission(String, int, int, String) with the pid and uid returned by Binder.getCallingPid() and Binder.getCallingUid(). One important difference is that if you are not currently processing an IPC, this function will always throw the SecurityException. This is done to protect against accidentally leaking permissions; you can use Context.enforceCallingOrSelfPermission(java.lang.String, java.lang.String) to avoid this protection.
    
    Specified by:
    
    enforceCallingPermission in class Context
    
    Parameters:

  - grantUriPermission
```
public void grantUriPermission(String toPackage,
                      Uri uri,
                      int modeFlags)
```
    Description copied from class: Context
    
    Grant permission to access a specific Uri to another package, regardless of whether that package has general permission to access the Uri's content provider. This can be used to grant specific, temporary permissions, typically in response to user interaction (such as the user opening an attachment that you would like someone else to display).
    Normally you should use Intent.FLAG_GRANT_READ_URI_PERMISSION or Intent.FLAG_GRANT_WRITE_URI_PERMISSION with the Intent being used to start an activity instead of this function directly. If you use this function directly, you should be sure to call Context.revokeUriPermission(android.net.Uri, int) when the target should no longer be allowed to access it.
    To succeed, the content provider owning the Uri must have set the grantUriPermissions attribute in its manifest or included the <grant-uri-permissions> tag.
    
    Specified by:
    
    grantUriPermission in class Context
    
    Parameters:
    toPackage - The package you would like to allow to access the Uri.
    uri - The Uri you would like to grant access to.
    modeFlags - The desired access modes. Any combination of Intent.FLAG_GRANT_READ_URI_PERMISSION or Intent.FLAG_GRANT_WRITE_URI_PERMISSION.
    See Also:
    Context.revokeUriPermission(android.net.Uri, int)
  - revokeUriPermission
```
public void revokeUriPermission(Uri uri,
                       int modeFlags)
```
    Description copied from class: Context
    
    Remove all permissions to access a particular content provider Uri that were previously added with Context.grantUriPermission(java.lang.String, android.net.Uri, int). The given Uri will match all previously granted Uris that are the same or a sub-path of the given Uri. That is, revoking "content://foo/one" will revoke both "content://foo/target" and "content://foo/target/sub", but not "content://foo".
    
    Specified by:
    
    revokeUriPermission in class Context
    
    Parameters:
    uri - The Uri you would like to revoke access to.
    modeFlags - The desired access modes. Any combination of Intent.FLAG_GRANT_READ_URI_PERMISSION or Intent.FLAG_GRANT_WRITE_URI_PERMISSION.

```
    Description copied from class: Context
    
    Determine whether a particular process and user ID has been granted permission to access a specific URI. This only checks for permissions that have been explicitly granted -- if the given process/uid has more general access to the URI's content provider then this check will always fail.

    Parameters:
    uri - The uri that is being checked.
    pid - The process ID being checked against. Must be > 0.
    uid - The user ID being checked against. A uid of 0 is the root user, which will pass every permission check.

                           int flags)
                             throws PackageManager.NameNotFoundException
```
    Description copied from class: Context
    
    Return a new Context object for the given application name. This Context is the same as what the named application gets when it is launched, containing the same resources and class loader. Each call to this method returns a new instance of a Context object; Context objects are not shared, however they share common state (Resources, ClassLoader, etc) so the Context instance itself is fairly lightweight.
    Throws PackageManager.NameNotFoundException if there is no application with the given package name.
    Throws SecurityException if the Context requested can not be loaded into the caller's process for security reasons (see Context.CONTEXT_INCLUDE_CODE for more information}.
    
    Specified by:
    
    createPackageContext in class Context
    
    Parameters:
    packageName - Name of the application's package.
    flags - Option flags, one of Context.CONTEXT_INCLUDE_CODE or Context.CONTEXT_IGNORE_SECURITY.
    
    Returns:
    A Context for the application.
    
    Throws:
    
    PackageManager.NameNotFoundException - if there is no application with the given package name
  - createPackageContextAsUser
```
public Context createPackageContextAsUser(String packageName,
                                 int flags,
                                 UserHandle user)
                                   throws PackageManager.NameNotFoundException
```
    Description copied from class: Context
    
    Similar to Context.createPackageContext(String, int), but with a different UserHandle. For example, Context.getContentResolver() will open any Uri as the given user.
    
    Specified by:
    
    createPackageContextAsUser in class Context
    
    Throws:
    
    PackageManager.NameNotFoundException
  - createConfigurationContext
```
public Context createConfigurationContext(Configuration overrideConfiguration)
```
    Description copied from class: Context
    
    Return a new Context object for the current Context but whose resources are adjusted to match the given Configuration. Each call to this method returns a new instance of a Context object; Context objects are not shared, however common state (ClassLoader, other Resources for the same configuration) may be so the Context itself can be fairly lightweight.
    
    Specified by:
    
    createConfigurationContext in class Context
    
    Parameters:
    overrideConfiguration - A Configuration specifying what values to modify in the base Configuration of the original Context's resources. If the base configuration changes (such as due to an orientation change), the resources of this context will also change except for those that have been explicitly overridden with a value here.
    
    Returns:
    A Context with the given configuration override.
  - createDisplayContext
```
public Context createDisplayContext(Display display)
```
    Description copied from class: Context
    
    Return a new Context object for the current Context but whose resources are adjusted to match the metrics of the given Display. Each call to this method returns a new instance of a Context object; Context objects are not shared, however common state (ClassLoader, other Resources for the same configuration) may be so the Context itself can be fairly lightweight. The returned display Context provides a WindowManager (see Context.getSystemService(String)) that is configured to show windows on the given display. The WindowManager's WindowManager.getDefaultDisplay() method can be used to retrieve the Display from the returned Context.
    
    Specified by:
    
    createDisplayContext in class Context
    
    Parameters:
    display - A Display object specifying the display for whose metrics the Context's resources should be tailored and upon which new windows should be shown.
    
    Returns:
    A Context for the display.
  - isRestricted
```
public boolean isRestricted()
```
    Description copied from class: Context
    
    Indicates whether this Context is restricted.
    
    Overrides:
    
    isRestricted in class Context
    
    Returns:
    True if this Context is restricted, false otherwise.
    See Also:
    Context.CONTEXT_RESTRICTED
  - getCompatibilityInfo
```
public CompatibilityInfoHolder getCompatibilityInfo(int displayId)
```
    Description copied from class: Context
    
    Gets the compatibility info holder for this context. This information is provided on a per-application basis and is used to simulate lower density display metrics for legacy applications.
    
    Specified by:
    
    getCompatibilityInfo in class Context
    
    Parameters:
    displayId - The display id for which to get compatibility info.
    
    Returns:
    The compatibility info holder, or null if not required by the application.
