Question

I am using broadcast receiver in my app to detect incomming call and it works fine. But problem is I can not send action to activity. I mean.. I want do something in activity not in receiver. I read many tutorial but they all are performing action in receiver. Any idea ?

You can declare a BroadcastReceiver as inner class of the Activity. In this case you can directly call activity’s methods:

public class MyActivity extends Activity {
    private final BroadcastReceiver receiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            activityMethod();
        }
    };

    private final IntentFilter filter = new IntentFilter("android.intent.action.PHONE_STATE");

    @Override
    protected void onStart() {
        super.onResume();
        registerReceiver(receiver, filter);
    }

    @Override
    protected void onStop() {
        super.onPause();
        unregisterReceiver(receiver);
    }

    private void activityMethod() {
    }
}
