How to turn off an alarm programmatically on Android

Question

I have an Android application. When the app is running, the alarm should be muted or disabled. After closing the application, the alarm should be enabled again. I used this code:

AudioManager AudiMngr = (AudioManager) getSystemService(AUDIO_SERVICE);
AudiMngr.setRingerMode(AudioManager.RINGER_MODE_SILENT);

AudiMngr.setStreamVolume(AudioManager.STREAM_ALARM, 0, AudioManager.FLAG_SHOW_UI + AudioManager.FLAG_PLAY_SOUND);

Toast toast = Toast.makeText(getApplicationContext(), "Sound Muted", Toast.LENGTH_SHORT);
toast.show();

But it works only at the time of application starting. When the alarm meets the alarm time, it is enabled. I wish to mute the alarm until the application closes. How can I do this?

To disable an alarm

AlarmManager aManager = (AlarmManager) getSystemService(ALARM_SERVICE);         
Intent intent = new Intent(getBaseContext(), YourAlarmSetClass.class);      
PendingIntent pIntent = PendingIntent.getBroadcast(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);         
aManager.cancel(pIntent);
