广播接收器“接收”方法没有被调用吗？

我
在活动A上有三个活动，我注册了广播接收者，然后从那里进入活动B，然后进入活动C。
最后onBackPressed是活动c，我发送了广播，但未onReceive调用

我的第一个活动

    private MyBroadCastReceiver myRecevier = new MyBroadCastReceiver();
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Submit.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub

                Intent frag=new Intent(MainActivity.this,Activity2.class);
                //frag.putExtra("Limit", foo);
                startActivity(frag);
                //  }
            }
        });
    }

    @Override
    protected void onResume() {
        super.onResume();
        //Register the activity to the broadcast receiver
        registerReceiver(myRecevier, new IntentFilter(MyBroadCastReceiver.ACTION));
    }

    @Override
    protected void onPause() {
        super.onPause();
        //Unregister the activity from the broadcast receiver. Good practice ;)
        unregisterReceiver(myRecevier);
    }

    public class MyBroadCastReceiver extends BroadcastReceiver{

        public static final String ACTION = "com.uberrueco.mybroadcastreceiver.receivers";
        @Override
        public void onReceive(Context context, Intent intent) {
            Log.d("MyBroadCastReceiver", "received");
            Toast.makeText(context,"Received "+intent.getStringExtra("editText"), Toast.LENGTH_LONG).show();

        }
    }
}

第二项活动只不过是一项活动3

第三次活动

    public class Activity3 extends Activity  {
    EditText etReceivedBroadcast;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity3);
        etReceivedBroadcast = (EditText) findViewById(R.id.etReceivedBroadcast);
    }
    @Override
    public void onBackPressed() {
        // TODO Auto-generated method stub
        super.onBackPressed();
        Intent intent = new Intent(this, MyIntentService.class);
        intent.putExtra("editText", etReceivedBroadcast.getText().toString());
        startService(intent);
    }
}

最后是我的IntentService课

    public class MyIntentService extends IntentService{

    public MyIntentService(){
        super("MyIntentService");
    }

    public MyIntentService(String name) {
        super(name);
    }

    @Override
    protected void onHandleIntent(Intent intent) {

        Log.d("MyIntentService", "handling intent...");

        //Intent created for broadcasting
        Intent intentBroadCast = new Intent();

        //Filter the broadcast to the action desired
        intentBroadCast.setAction(MyBroadCastReceiver.ACTION); 
        intentBroadCast.putExtra("editText", intent.getStringExtra("editText"));
        //Send the broadcast :D
        sendBroadcast(intentBroadCast);
    }
}
