Doing an activity when mobile is silent

Question

I am trying to make an android app which sends a message automatically when you get a miss call but only when the mobile is silent . I know how to send message when there is a miss call but i don't know to check whether the state of mobile is Silent or not .
Is it even possible to check the state of the mobile and if so how ??
Thank you in advance .

You can do that with AudioManager like this:

AudioManager audioManager = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);
switch(audioManager.getRingerMode()){
   case AudioManager.RINGER_MODE_NORMAL:
      // Phone is loud
      break;

   case AudioManager.RINGER_MODE_SILENT:
      // Phone is silent
      break;

   case AudioManager.RINGER_MODE_VIBRATE:
      // Phone is vibrating
      break;
}
