NullPointerException при sendBroadcast () из Сервиса в Активность

У меня есть класс Service и основной класс Acitivity который должен получать трансляции из класса Service с помощью метода sendBroadcast.

Он сбой при запуске метода sendBroadcast из моего класса Service.

вот часть моего класса сервиса (EDITED):

    public static final int STATE_CONNECTING = 1;

    public static final String BT_CONNECTING = "com.android.mypackage.action.BTService.BT_CONNECTING";

    private final IBinder mBinder = new LocalBinder();

    public class LocalBinder extends Binder() {
            BTService getService() {
                    return BTService.this;
            }
    }

    @Override
    public IBinder onBind(Intent intent) {
            return mBinder;
    }

    public synchronized void setState(int state) {
            mState = state;
            if ( state == STATE_CONNECTING ) {
                    Intent myIntent = new Intent(BT_CONNECTING);
                    try {
                            sendBroadcast(myIntent);
                    }
                    catch (NullPointerException e) {}
            }
    }

И вот часть моего класса Activity, которая должна получать трансляции (EDITED):

    private BroadcastReceiver receiver = new BroadcastReceiver() {
            @Override
            public void onReceive(Context context, Intent intent) {
                    if(intent.getAction().equals(BTService.BT_CONNECTING))
                            mState = STATE_CONNECTING;
                    }
            };

    private ServiceConnection mConnection = new ServiceConnection() {
            public void onServiceConnected(ComponentName className, IBinder service) {
                    LocalBinder binder = (LocalBinder) service;
                    myService = binder.getService();
                    mBound = true;
            }

            public void onServiceDisconnected(ComponentName arg0) {
                    mBound = false;
            }
    };

    @Override
    public void onCreate(Bundle savedInstanceState) {
            Intent intent = new Intent(this, BTService.class);
            myService.bindService(intent, mConnection, Context.BIND_AUTO_CREATE);

            IntentFilter filter = new IntentFilter(BTService.BTConnecting);
            registerReceiver(receiver, filter);
    }

Я получаю NullPointerException при вызове метода sendBroadcast (намерения). Любые советы по его решению очень приветствуются.
