Question

I have this simple java code:

package com.androiddesktoptest.testtest;

public class AndroidDesktopTestMain
{
    public static void main(String[] args)
    {
        callFromAndroid();
    }

    public static void callFromAndroid()
    {
        System.out.println("DESKTOP CODE CALLED FROM ANDROID");
    }
}

And I want to call it from Android like this:

import com.androiddesktoptest.testtest.AndroidDesktopTestMain;

public void onCreate(Bundle savedInstanceState)
{
    //...
    AndroidDesktopTestMain.callFromAndroid();
}

and I get java.lang.NoClassDefFoundError

I am using Eclipse and my project AndroidDesktopTest has checked to export AndroidDesktopTest/src. Also, eclipse autocomplete my code in Android, so it see correcly my code in desktop project.

What I am doing wrong? I did something like this in my previous-previous-previous project, from this time, maybe ADT has chaged or something…

* UPDATE *

Sounds like you don’t get the class over to the phone when u run your android.

Make sure that:

right click project – properties – java build path – Order and Export (is it checked here?)
