Class UserHandle

  • All Implemented Interfaces:

    public final class UserHandle
    extends Object
    implements Parcelable
    Representation of a user on the device.
    • Constructor Detail

      • UserHandle

        public UserHandle(int h)
      • UserHandle

        public UserHandle(Parcel in)
        Instantiate a new UserHandle from the data in a Parcel that was previously written with writeToParcel(Parcel, int). Note that you must not use this with data written by writeToParcel(UserHandle, Parcel) since it is not possible to handle a null UserHandle here.
        in - The Parcel containing the previously written UserHandle, positioned at the location in the buffer where it was written.
    • Method Detail

      • isSameUser

        public static final boolean isSameUser(int uid1,
                         int uid2)
        Checks to see if the user id is the same for the two uids, i.e., they belong to the same user.
      • isSameApp

        public static final boolean isSameApp(int uid1,
                        int uid2)
        Checks to see if both uids are referring to the same app id, ignoring the user id part of the uids.
        uid1 - uid to compare
        uid2 - other uid to compare
        whether the appId is the same for both uids
      • isIsolated

        public static final boolean isIsolated(int uid)
      • isApp

        public static boolean isApp(int uid)
      • getUserId

        public static final int getUserId(int uid)
        Returns the user id for a given uid.
      • getCallingUserId

        public static final int getCallingUserId()
      • getUid

        public static final int getUid(int userId,
                 int appId)
        Returns the uid that is composed from the userId and the appId.
      • getAppId

        public static final int getAppId(int uid)
        Returns the app id (or base uid) for a given uid, stripping out the user id from it.
      • getSharedAppGid

        public static final int getSharedAppGid(int id)
        Returns the shared app gid for a given uid or appId.
      • myUserId

        public static final int myUserId()
        Returns the user id of the current process
        user id of the current process
      • getIdentifier

        public int getIdentifier()
      • toString

        public String toString()
        Description copied from class: Object
        Returns a string containing a concise, human-readable description of this object. Subclasses are encouraged to override this method and provide an implementation that takes into account the object's type and data. The default implementation is equivalent to the following expression:
           getClass().getName() + '@' + Integer.toHexString(hashCode())

        See Writing a useful toString method if you intend implementing your own toString method.

        toString in class Object
        a printable representation of this object.
      • equals

        public boolean equals(Object obj)
        Description copied from class: Object
        Compares this instance with the specified object and indicates if they are equal. In order to be equal, o must represent the same object as this instance using a class-specific comparison. The general contract is that this comparison should be reflexive, symmetric, and transitive. Also, no object reference other than null is equal to null.

        The default implementation returns true only if this == o. See Writing a correct equals method if you intend implementing your own equals method.

        The general contract for the equals and Object.hashCode() methods is that if equals returns true for any two objects, then hashCode() must return the same value for these objects. This means that subclasses of Object usually override either both methods or neither of them.

        equals in class Object
        obj - the object to compare this instance with.
        true if the specified object is equal to this Object; false otherwise.
        See Also:
      • hashCode

        public int hashCode()
        Description copied from class: Object
        Returns an integer hash code for this object. By contract, any two objects for which Object.equals(java.lang.Object) returns true must return the same hash code value. This means that subclasses of Object usually override both methods or neither method.

        Note that hash values must not change over time unless information used in equals comparisons also changes.

        See Writing a correct hashCode method if you intend implementing your own hashCode method.

        hashCode in class Object
        this object's hash code.
        See Also:
      • describeContents

        public int describeContents()
        Description copied from interface: Parcelable
        Describe the kinds of special objects contained in this Parcelable's marshalled representation.
        Specified by:
        describeContents in interface Parcelable
        a bitmask indicating the set of special object types marshalled by the Parcelable.
      • writeToParcel

        public static void writeToParcel(UserHandle h,
                         Parcel out)
        Write a UserHandle to a Parcel, handling null pointers. Must be read with readFromParcel(Parcel).
        h - The UserHandle to be written.
        out - The Parcel in which the UserHandle will be placed.
        See Also:
      • readFromParcel

        public static UserHandle readFromParcel(Parcel in)
        Read a UserHandle from a Parcel that was previously written with writeToParcel(UserHandle, Parcel), returning either a null or new object as appropriate.
        in - The Parcel from which to read the UserHandle
        Returns a new UserHandle matching the previously written object, or null if a null had been written.
        See Also:
        writeToParcel(UserHandle, Parcel)
