Answer 1

With API 8, I got my broadcast receiver called without creating a service or requesting for extra permissions.

You can define an inner class within your main activity similar to the one I've defined below:

public class HeadSetBroadCastReceiver extends BroadcastReceiver
    {

        @Override
        public void onReceive(Context context, Intent intent) {

            // TODO Auto-generated method stub
            String action = intent.getAction();
            Log.i("Broadcast Receiver", action);
            if( (action.compareTo(Intent.ACTION_HEADSET_PLUG))  == 0)   //if the action match a headset one
            {
                int headSetState = intent.getIntExtra("state", 0);      //get the headset state property
                int hasMicrophone = intent.getIntExtra("microphone", 0);//get the headset microphone property
                if( (headSetState == 0) && (hasMicrophone == 0))        //headset was unplugged & has no microphone
                {
                               //do whatever
                }
            }           

        }

    }

Then, register your broadcast receiver either dynamically or statically. I registered mine dynamically in my Activity's onCreate() method:

this.registerReceiver(headsetReceiver, new IntentFilter(Intent.ACTION_HEADSET_PLUG));

Make sure that you unregister your BroadcastReceiver with the Context's unregisterReceiver. In my case, I did this in the onDestroy() method. That should do it.
