手机静音时有声音通知 [英] Notification with sound although phone is muted

问题描述

我正在使用Android的NotificationManager创建通知.

I am creating a notification with Android's NotificationManager.

是否可以以始终播放通知的声音的方式覆盖"电话的音量(静音)设置?

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

我需要这个的原因如下: 该通知非常重要，以至于仅靠振动可能还不够.必须提醒用户.因此，即使手机已静音或音量很低，也应播放声音.

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.

推荐答案

是的，

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();

            }

        });
