how can I detect whether the android phone in Silent mode programmatically

How to identify whether the phone is in Silent mode or not?

I am using Android 1.5. I tried by using "android.provider.Settings.ACTION_SOUND_SETTINGS". It is not working.

Use the getRingerMode() method in AudioManager.

AudioManager am = (AudioManager)getSystemService(Context.AUDIO_SERVICE);
    
switch (am.getRingerMode()) {
    case AudioManager.RINGER_MODE_SILENT:
        Log.i("MyApp","Silent mode");
        break;
    case AudioManager.RINGER_MODE_VIBRATE:
        Log.i("MyApp","Vibrate mode");
        break;
    case AudioManager.RINGER_MODE_NORMAL:
        Log.i("MyApp","Normal mode");
        break;
}

Following code checks if phone is not in silent mode then plays a beep, written in kotlin:

    val manager = getSystemService(Context.AUDIO_SERVICE) as AudioManager
    manager.setStreamVolume(AudioManager.STREAM_MUSIC, 10, 0)
    val notification = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION)
    val player: MediaPlayer = MediaPlayer.create(applicationContext, notification)
    if(manager.ringerMode != AudioManager.RINGER_MODE_SILENT)
        player.start()
