Cant get my Android extension work [NOT solved]

[DigitalRealms]

GMS 1.4999
I tried to create a simple Android extension, but the result im getting is 'undefined'. What am i doing wrong?
To create extension i right click on it and choose - 'Add Android Source', but nothing shows up.
Here is my Java source code

package ${YYAndroidPackageName};

import ${YYAndroidPackageName}.R;
import com.yoyogames.runner.RunnerJNILib;

public class MainClass
{

    public double AddTwoNumbers(double arg0, double arg1) {
        double value = arg0 + arg1;
        return value;
    }

}

I haven't used GMS 1.4 w/ android for a very long time so I'm not sure if the following is still accurate.

Last time I made an android extension (w/ Java) I had to actually export the project to the device and run it for the extension to properly compile. Simply 'running' through the editor would not work and would give me errors.

Give it a go and see if it works.
