    public static StorageVolume fromTemplate(StorageVolume template,

                             UserHandle owner)

  • getPath

    public String getPath()

    Returns the mount path for the volume.

    Returns:

    the mount path

  • getPathFile

    public File getPathFile()

  • getDescription

    public String getDescription(Context context)

    Returns a user visible description of the volume.

    Returns:

    the volume description

  • getDescriptionId

    public int getDescriptionId()

  • isPrimary

    public boolean isPrimary()

  • isRemovable

    public boolean isRemovable()

    Returns true if the volume is removable.

    Returns:

    is removable

  • isEmulated

    public boolean isEmulated()

    Returns true if the volume is emulated.

    Returns:

    is removable

  • getStorageId

    public int getStorageId()

    Returns the MTP storage ID for the volume. this is also used for the storage_id column in the media provider.

    Returns:

    MTP storage ID

  • setStorageId

    public void setStorageId(int index)

    Do not call this unless you are MountService

  • getMtpReserveSpace

    public int getMtpReserveSpace()

    Number of megabytes of space to leave unallocated by MTP. MTP will subtract this value from the free space it reports back to the host via GetStorageInfo, and will not allow new files to be added via MTP if there is less than this amount left free in the storage. If MTP has dedicated storage this value should be zero, but if MTP is sharing storage with the rest of the system, set this to a positive value to ensure that MTP activity does not result in the storage being too close to full.

    Returns:

    MTP reserve space

  • allowMassStorage

    public boolean allowMassStorage()

    Returns true if this volume can be shared via USB mass storage.

    Returns:

    whether mass storage is allowed

  • getMaxFileSize

    public long getMaxFileSize()

    Returns maximum file size for the volume, or zero if it is unbounded.

    Returns:

    maximum file size

  • getOwner

    public UserHandle getOwner()

  • 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.

    Overrides:

    equals in class Object

    Parameters:

    obj - the object to compare this instance with.

    Returns:

    true if the specified object is equal to this Object; false otherwise.

    See Also:

    Object.hashCode()

  • 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.

    Overrides:

    hashCode in class Object

    Returns:

    this object's hash code.

    See Also:

    Object.equals(java.lang.Object)

  • 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.

    Overrides:

    toString in class Object

    Returns:

    a printable representation of this object.

  • 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

    Returns:

    a bitmask indicating the set of special object types marshalled by the Parcelable.

  • writeToParcel

    public void writeToParcel(Parcel parcel,
                     int flags)

    Description copied from interface: Parcelable
    Flatten this object in to a Parcel.

    Specified by:

    writeToParcel in interface Parcelable

    Parameters:

    parcel - The Parcel in which the object should be written.

    flags - Additional flags about how the object should be written. May be 0 or Parcelable.PARCELABLE_WRITE_RETURN_VALUE.
