Android Studio: не может разрешить Symbol VolumeproviderCompat ⇐ Android

[Anonymous]

В Android Studio не может найти способ импортировать ' android.support.v4.media.volumeprovidercompat '. Правильно.import android.app.Service;
import android.content.Intent;
import android.os.IBinder;
import android.support.v4.media.session.MediaSessionCompat;
import android.support.v4.media.session.PlaybackStateCompat;
import android.support.v4.media.VolumeProviderCompat;
import android.util.Log;

public class InputTest Service{

private MediaSessionCompat mediaSession;

@Override
public void onCreate() {
super.onCreate();
mediaSession = new MediaSessionCompat(this, "PlayerService");
mediaSession.setFlags(MediaSessionCompat.FLAG_HANDLES_MEDIA_BUTTONS |
MediaSessionCompat.FLAG_HANDLES_TRANSPORT_CONTROLS);
mediaSession.setPlaybackState(new PlaybackStateCompat.Builder()
.setState(PlaybackStateCompat.STATE_PLAYING, 0, 0) //you simulate a player which plays something.
.build());

//this will only work on Lollipop and up, see https://code.google.com/p/android/issue ... ?id=224134
VolumeProviderCompat myVolumeProvider =
new VolumeProviderCompat(VolumeProviderCompat.VOLUME_CONTROL_RELATIVE, /*max volume*/100, /*initial volume level*/50) {
@Override
public void onAdjustVolume(int direction) {

/*
-1 -- volume down
1 -- volume up
0 -- volume button released
*/
}
};

mediaSession.setPlaybackToRemote(myVolumeProvider);
mediaSession.setActive(true);
}

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
return Service.START_NOT_STICKY;
}

@Override
public IBinder onBind(Intent intent) {
//TODO for communication return IBinder implementation
return null;
}

@Override
public void onDestroy() {
super.onDestroy();
mediaSession.release();
}

}
