Pass the greater of two entered numbers from one app and have a receiver broadcast it in another

Question

So I'm having trouble trying to pass the greater of two entered numbers from one app and then have the receiver broadcast it in another. Here's code from the sending app:

public class MainActivity extends AppCompatActivity {

    private EditText etFirst;
    private EditText etSecond;
    private Button btSend;
    private int num;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        etFirst = (EditText) findViewById(R.id.etFirst);
        etSecond =(EditText) findViewById(R.id.etSecond);
        btSend = (Button) findViewById(R.id.btSend);

        btSend.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

                int a = Integer.parseInt(etFirst.getText().toString());
                int b = Integer.parseInt(etSecond.getText().toString());

                if (a > b) {
                    num = a;
                }
                else {
                    num = b;
                }

                Intent intent = new Intent("com.numb.sending.intent");
                intent.putExtra("com.numb.sending.intent.params", num);
                sendBroadcast(intent);
            }
        });

    }


}

Code from the receiving app:

public class MainActivity extends AppCompatActivity {

    private Button btReceive;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        btReceive = (Button) findViewById(R.id.btReceive);

        btReceive.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Intent intent = new Intent(MyReceiver.INTENT);
                intent.putExtra(MyReceiver.PARAM);
                sendBroadcast(intent);
            }
        });
    }
}

My receiver:

public class MyReceiver extends BroadcastReceiver {
    public static final String PARAM = "com.numb.sending.intent.params";
    public static final String INTENT = "com.numb.sending.intent";


    public MyReceiver() {
    }


    @Override
    public void onReceive(Context context, Intent intent) {

        if (intent.hasExtra(PARAM)) {
            String value = intent.getStringExtra(PARAM);
            Toast.makeText(context, value, Toast.LENGTH_SHORT).show();
        }
    }
}

Any help?
