Question

I have a class that extends BroadcastReceiver that reads new sms

public class SmsReceiver extends BroadcastReceiver
{
   // reading sms
   // I want to send the sms text to my main activity
}

And have another class in the same app that is my main Activity.
So when I receive new sms, I want to send its content to my main Activity that is already running and display it.
How can I do that?
I would be thankful for some code samples 🙂

Answer 1

i can suggest you two possibilities

1. send new broadcasts from this receiver to a new receiver which is registered inside your activity
2. register this receiver inside your activity and reduce the hassle

i guess option two is more suitable

this is how you may register a broadcast receiver inside your activity class:

IntentFilter filter = new IntentFilter();

public void onResume(){
    filter.addAction("action_string_1");
    filter.addAction("action_string_2");

    registerReceiver(receiver, filter);
}

public void onPause(){
    unregisterReceiver(receiver);
}

BroadcastReceiver receiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            String action = intent.getAction();

            if(action.equals("action_string_1")){
                //do something here
            }
            else if(action.equals("action_string_2")){
                //do somethign here
            }
        }
    };
