How can I detect if the volume is set to mute?

When I am developing an Android application, how can I detect if volume is set to mute?

How can my application get notified if the volume changes to mute or gets unmuted?

You can do the following to observe if a specific stream (music in this case) is muted:

val Context.musicMutedFlow
    get() = callbackFlow {
        val receiver = object : BroadcastReceiver() {
            override fun onReceive(context: Context, intent: Intent) {
                when (intent.getIntExtra("android.media.EXTRA_VOLUME_STREAM_TYPE", 0)) {
                    AudioManager.STREAM_MUSIC -> trySend(
                        intent.getBooleanExtra(
                            "android.media.EXTRA_STREAM_VOLUME_MUTED",
                            false
                        )
                    )
                }
            }
        }

        registerReceiver(receiver, IntentFilter("android.media.STREAM_MUTE_CHANGED_ACTION"))
        awaitClose { unregisterReceiver(receiver) }
    }

Then, from a ContextWrapper (e.g., Activity, Service), you can collect the flow as follows:

lifecycleScope.launch {
    musicMutedFlow.collect { Log.d("Some tag", "Music stream muted: $it") }
}

If, like in the accepted answer, you want to specifically know if the Ring and notification volume is muted, you may instead want to do the following:

val Context.ringAndNotificationMutedFlow
    get() = callbackFlow {
        val receiver = object : BroadcastReceiver() {
            override fun onReceive(context: Context, intent: Intent) {
                val ringerMode = intent.getIntExtra(
                    AudioManager.EXTRA_RINGER_MODE,
                    AudioManager.RINGER_MODE_NORMAL
                )

                trySend(ringerMode != AudioManager.RINGER_MODE_NORMAL)
            }
        }

        registerReceiver(receiver, IntentFilter(AudioManager.RINGER_MODE_CHANGED_ACTION))
        awaitClose { unregisterReceiver(receiver) }
    }

The advantage is that the AudioManager constants used are public and Google would have to mark them for deprecation if they were to change them or remove them.

You can use AudioManager to check volume is mute or not mute.

AudioManager audio = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);
switch( audio.getRingerMode() ){
case AudioManager.RINGER_MODE_NORMAL:
   break;
case AudioManager.RINGER_MODE_SILENT:
   break;
case AudioManager.RINGER_MODE_VIBRATE:
   break;
}

and for Volume change there is BroadcastReceiver for that.

public class VolumeKeyReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
       //Implement Logic
    }
}

Register the BroadcastReceiver

VolumeKeyReceiver keyReceiver = new VolumeKeyReceiver();
IntentFilter intentFilter = new IntentFilter();
intentFilter.addAction("android.media.VOLUME_CHANGED_ACTION");
registerReceiver(keyReceiver, intentFilter);
