Alternative to the deprecated AudioManager.isWiredHeadsetOn?

Question

The method AudioManager.isWiredHeadsetOn() is deprecated from api level 14, how do we now detect if a wired headset is connected?

Answer 1

IntentFilter iFilter = new IntentFilter(Intent.ACTION_HEADSET_PLUG);
Intent iStatus = context.registerReceiver(null, iFilter);
boolean isConnected = iStatus.getIntExtra("state", 0) == 1;

I do know this code can be used on which andorid platform version. It does not work for me on Android 8. Result iStatus is null.
