MediaController

public final class MediaController
extends Object

java.lang.Object
↳	android.media.session.MediaController

Allows an app to interact with an ongoing media session. Media buttons and other commands can be sent to the session. A callback may be registered to receive updates from the session, such as metadata and play state changes.

A MediaController can be created through MediaSessionManager if you hold the "android.permission.MEDIA_CONTENT_CONTROL" permission or are an enabled notification listener or by getting a MediaSession.Token directly from the session owner.

MediaController objects are thread-safe.

Inherited methods

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 millis, 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 millis)` 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.

Parameters
`context`	`Context`: The caller's context.
`token`	`MediaSession.Token`: The token for the session.

Parameters
`direction`	`int`: The direction to adjust the volume in.
`flags`	`int`: Any flags to pass with the command.

Parameters
`callback`	`MediaController.Callback`: The callback object, must not be null.
`handler`	`Handler`: The handler to post updates on. If null the callers thread will be used.

Parameters
`command`	`String`: The command to send
`args`	`Bundle`: Any parameters to include with the command
