Call A Method In Activity When Certain Data Recived

I'm trying to build an app that call a method in activity when a certain data is received from server, I use socket for my conection to server and when a certain message recived it

Solution 1:

One way to achieve this is by using BroadcastReceivers. In your class that received the message from the server you can raise an intent like

StringserverResponse= ...;
Stringaction="MESSAGE_RECEIVED_FROM_SERVER";
Intentintent=newIntent();
intent.setAction(action);
intent.putExtra("msg", serverResponse );

context.sendBroadcast(intent);

And now in your activity you need to create an Broadcast Receiver that will register for the MESSAGE_RECEIVED_FROM_SERVERintent. And when receiving the intent you can call the desired method from the activity.

You can use an example from tutorialspoint or vogella.

Hope it helps.
