Question

This code isn’t work. What happen?

public class Main extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        registerReceiver(br, new IntentFilter("a.b.c.d"));
        Intent it = new Intent("a.b.c.d");
        startActivity(it);
    }
    BroadcastReceiver br = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        Toast.makeText(context, "test", Toast.LENGTH_SHORT);
    }
    };
}

If you are simply trying to test the receiver, replace startActivity(it) with sendBroadcast(it).
