Android mute/unmute phone

My goal is to support 2 operations:

• mute phone (possibly with vibrations enabled/disabled), so开发者_如何学编程 when a call or sms is received it won't make noise

• unmute phone and restore the volume to the state before muting phone

How can I do this? What permissions are required in AndroidManifest?

This is the permission for vibrate into the manifest file

<uses-permission android:name="android.permission.VIBRATE" />

this is for to put the device in silent mode with vibrate

AudioManager audioManager = (AudioManager)context.getSystemService(Context.AUDIO_SERVICE);
audioManager.setRingerMode(AudioManager.RINGER_MODE_VIBRATE);

this is for to put into the ringing mode

AudioManager audioManager = (AudioManager)context.getSystemService(Context.AUDIO_SERVICE);
int maxVolume = audioManager.getStreamMaxVolume(AudioManager.STREAM_RING);

audioManager.setRingerMode(AudioManager.RINGER_MODE_NORMAL);
audioManager.setStreamVolume(AudioManager.STREAM_RING, maxVolume, AudioManager.FLAG_SHOW_UI + AudioManager.FLAG_PLAY_SOUND);

public void changeRingerMode(Context context){

AudioManager audio = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);

    /**
    * To Enable silent mode.....
    */
    audio.setRingerMode(AudioManager.RINGER_MODE_SILENT);

    /**
    * To Enable Ringer mode.....
    */
    audio.setRingerMode(AudioManager.RINGER_MODE_NORMAL);

}

If what you want is to disable sound and restore the sound setting to previous state, this worked for me.

static int ringstate = 0;
private void soundOn(boolean off){
AudioManager audio = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);
   if(off)
    {   //turn off ringing/sound
     //get the current ringer mode
     ringstate = audio.getRingerMode();
     if(ringstate!=AudioManager.RINGER_MODE_SILENT)
      audio.setRingerMode(AudioManager.RINGER_MODE_SILENT);//turn off
    }
  else
  {
    //restore previous state
    audio.setRingerMode(ringstate);


  }

}

This should do.
