Final code:

App 1 :

        Intent intent = new Intent();
        intent.setClassName("com.appstore", "com.appstore.MyBroadcastReceiver");
        intent.setAction("com.appstore.MyBroadcastReceiver");
        intent.putExtra("KeyName","code1id");
        sendBroadcast(intent);

App 2:

Reciver:
public class MyBroadcastReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        Toast.makeText(context, "Data Received from External App", Toast.LENGTH_SHORT).show();

    }
}

Manifest :

MainActivity :

  MyBroadcastReceiver mReceiver = new MyBroadcastReceiver();
        registerReceiver(mReceiver,
                new IntentFilter("first_app_packagename"));
