In one screen I have a looping background video (upon which normal UI elements are shown), implemented with VideoView like this:
String resPath = "android.resource://" + getPackageName() + "/" + R.raw.bg_video;
videoView.setVideoURI(Uri.parse(resPath));
// Hide controls:
MediaController controller = new MediaController(getActivity());
controller.setVisibility(View.GONE);
videoView.setMediaController(controller);
// Use looping:
videoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
@Override
public void onPrepared(MediaPlayer mp) {
mp.setLooping(true);
}
});
videoView.start();
The video works great. The only problem is that when this view is shown (or even before if using e.g. ViewPager), music playback from other applications stops.
The video I'm using has no sound itself. Is there a way to set the VideoView, or the MediaPlayer it uses, in a "muted mode"? I.e., tell it not to do audio at all, and especially not to mess with other apps' audio.
Tried mp.setVolume(0, 0);
in onPrepared()
but it has no effect.
Copy paste VideoView
from Android sources and comment out these lines:
AudioManager am = (AudioManager) getContext().getSystemService(Context.AUDIO_SERVICE);
am.requestAudioFocus(null, AudioManager.STREAM_MUSIC, AudioManager.AUDIOFOCUS_GAIN);
You could name the new class MutedVideoView
, for example.

The accepted solution does not guarantee compatibility across all Android versions and is a dirty hack more than a true solution. I've tried all forms of hacks to get this working, yet none have worked to my satisfaction.
I have come up with a much better solution though - switch from a VideoView
to a TextureView
and load it with a MediaPlayer
. There is no difference from the user's perspective, just no more audio stoppage.
Here's my use case for playing an MP4 looping:
private TextureView _introVideoTextureView;
private MediaPlayer _introMediaPlayer;
...
@Override
public void onCreate(...) {
_introVideoTextureView.setSurfaceTextureListener(new TextureView.SurfaceTextureListener() {
@Override
public void onSurfaceTextureAvailable(SurfaceTexture surfaceTexture, int width, int height) {
try {
destoryIntroVideo();
_introMediaPlayer = MediaPlayer.create(SignInActivity.this, R.raw.intro_video);
_introMediaPlayer.setSurface(new Surface(surfaceTexture));
_introMediaPlayer.setLooping(true);
_introMediaPlayer.setVideoScalingMode(MediaPlayer.VIDEO_SCALING_MODE_SCALE_TO_FIT_WITH_CROPPING);
_introMediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
@Override
public void onPrepared(MediaPlayer mediaPlayer) {
mediaPlayer.start();
}
});
} catch (Exception e) {
System.err.println("Error playing intro video: " + e.getMessage());
}
}
@Override
public void onSurfaceTextureSizeChanged(SurfaceTexture surfaceTexture, int i, int i1) {}
@Override
public boolean onSurfaceTextureDestroyed(SurfaceTexture surfaceTexture) {
return false;
}
@Override
public void onSurfaceTextureUpdated(SurfaceTexture surfaceTexture) {}
});
}
@Override
public void onDestroy() {
super.onDestroy();
destoryIntroVideo();
}
private void destoryIntroVideo() {
if (_introMediaPlayer != null) {
_introMediaPlayer.stop();
_introMediaPlayer.release();
_introMediaPlayer = null;
}
}
