    One easy way is by using static variables.

    On the MainActivity add the following:

    public class MainActivity extends AppCompatActivity{
    public static SmsMessage result;
    //...
}

    Then, add the following line MainActivity.result = smsMessage to the code you provided just after you get the message.

    Then you can use the variable result in any part of the MainActivity (also by calling MainActivity.result you have the value of the variable in any part of your code).

    Just be careful, static variables are defined as null before any assignment.

    The abstract keyword is a non-access modifier, used for classes and methods:

    Abstract class: is a restricted class that cannot be used to create objects (to access it, it must be inherited from another class).

    Abstract method: can only be used in an abstract class, and it does not have a body. The body is provided by the subclass (inherited from).

    In your activity:

    public class MyActivity extends Activity {

    private smsReceiver SmsBroadcastReceiver;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.map_one_position);
        smsReceiver = new SmsBroadcastReceiver() {

            // this code is call asyncrously from the receiver
            @Override
            protected void onSmsReceived() {
                 // Add your activty logic here
            }

        };

    }

     @Override
        protected void onPause() {
            super.onPause();
            this.unregisterReceiver(this.smsReceiver);
        }

}
