FileDataSourceDesc

public class FileDataSourceDesc
extends DataSourceDesc

java.lang.Object
↳	android.media.DataSourceDesc
	↳	android.media.FileDataSourceDesc

Structure of data source descriptor for sources using file descriptor. Used by MediaPlayer2#setDataSource, MediaPlayer2#setNextDataSource and MediaPlayer2#setNextDataSources to set data source for playback.

Users should use Builder to create FileDataSourceDesc.

Summary

Nested classes
`class`	`FileDataSourceDesc.Builder` Builder class for `FileDataSourceDesc` objects.

Constants
`long`	`FD_LENGTH_UNKNOWN` Used when the length of file descriptor is unknown.

Inherited constants

From class android.media.DataSourceDesc

`long`	`LONG_MAX_TIME_MS`
`long`	`POSITION_UNKNOWN`

Public methods
`long`	`getLength()` Return the content length associated with the ParcelFileDescriptor of this data source.
`long`	`getOffset()` Return the offset associated with the ParcelFileDescriptor of this data source.
`ParcelFileDescriptor`	`getParcelFileDescriptor()` Return the ParcelFileDescriptor of this data source.

Inherited methods

From class


        
          android.media.DataSourceDesc

`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`long`	`getEndPosition()` Return the position in milliseconds at which the playback will end.
`String`	`getMediaId()` Return the media Id of data source.
`long`	`getStartPosition()` Return the position in milliseconds at which the playback will start.
`String`	`toString()` Returns a string representation of the object.

From class


        
          java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeout, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void`	`wait(long timeout)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void`	`wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.

Public methods

getLength

Added in Android Q

public long getLength ()

getParcelFileDescriptor

Added in Android Q

public ParcelFileDescriptor getParcelFileDescriptor ()

Return the ParcelFileDescriptor of this data source.

Returns
`ParcelFileDescriptor`	the ParcelFileDescriptor of this data source
