Below code is working for me.

MainActivity.java:

public class MainActivity extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        startService( new Intent(this, Receiver.class) );
}
}

BackgroundService.java

public class Receiver extends Service {
    private static final String BCAST_CONFIGCHANGED = "android.intent.action.CONFIGURATION_CHANGED";
    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }

    @Override
    public void onCreate() {
        IntentFilter filter = new IntentFilter();
        filter.addAction(BCAST_CONFIGCHANGED);
        this.registerReceiver(mBroadcastReceiver, filter);
    }

    @Override
    public void onDestroy() {
    }

    @Override
    public void onStart(Intent intent, int startid) {
    }

    public BroadcastReceiver mBroadcastReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent myIntent) {
            if ( myIntent.getAction().equals( BCAST_CONFIGCHANGED ) ) {
                if(getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE){
                }
                else {
                }
            }
        }
    };
}
