Android - make phone silent for a limited amounts of time (dyanmically)

问题

I want to put my phone on silent mode for a shorter amount of time.

I am using the following code to put my phone on silent mode and it works. However the next segment doesn't put it back to ringer mode/previous mode.

 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
            // turn off beep sounds
                mAudioManager.setStreamMute(AudioManager.STREAM_NOTIFICATION, true);
                mAudioManager.setStreamMute(AudioManager.STREAM_ALARM, true);
                mAudioManager.setStreamMute(AudioManager.STREAM_MUSIC, true);
                mAudioManager.setStreamMute(AudioManager.STREAM_RING, true);
                mAudioManager.setStreamMute(AudioManager.STREAM_SYSTEM, true);
        }

This to put it back on previous state:

    public void destroy()
{
        mAudioManager.setStreamMute(AudioManager.STREAM_NOTIFICATION, false);
        mAudioManager.setStreamMute(AudioManager.STREAM_ALARM, false);
        mAudioManager.setStreamMute(AudioManager.STREAM_MUSIC, false);
        mAudioManager.setStreamMute(AudioManager.STREAM_RING, false);
        mAudioManager.setStreamMute(AudioManager.STREAM_SYSTEM, false);


    Log.d(TAG, "onDestroy"); }

I tested by exiting the app also by manually calling those codes in onDestory on a seperate methode but got no success,it stays silent.

It will be better if I can put my phone on silent mode for a small amounts of time.

Thanks.

Create an Alarm using AlarmManager when you want to put your phone to Silent Mode make your device silent that time
Assign time in AlarmManager when you want to stop it. Receive the alarm using BroadcastReceiver and stop the silent Mode.
