Notification with sound although phone is muted

Question

I am creating a notification with Android's NotificationManager.

Is it possible to 'override' the phone's volume (mute) settings in such a way, that the notification's sound is ALWAYS played?

The reason I need this is the following: The notification is so important, that vibration alone may not be enough. The user MUST be alerted. So a sound shall be played, even if the phone is muted or the volume is very low.

Answer 1

yes it is possible,

MediaPlayer mMediaPlayer;
Uri notification = null;
notification = RingtoneManager
                .getDefaultUri(RingtoneManager.TYPE_ALARM);

mMediaPlayer = new MediaPlayer();
        mMediaPlayer.setDataSource(ctx, notification);
        // mMediaPlayer = MediaPlayer.create(ctx, notification);
        final AudioManager audioManager = (AudioManager) ctx
                .getSystemService(Context.AUDIO_SERVICE);

        mMediaPlayer.setAudioStreamType(AudioManager.STREAM_ALARM);

        mMediaPlayer.prepare();
        // mMediaPlayer.start();
        mMediaPlayer.setLooping(true);
        mMediaPlayer.setOnPreparedListener(new OnPreparedListener() {
            public void onPrepared(MediaPlayer arg0) {
                mMediaPlayer.seekTo(0);
                mMediaPlayer.start();

            }

        });
