Cannot find class when refrencing from another project

Question

I have looked at the following which I thought would work but it did not.

Could not find class XXX referenced from method XXX.

Hello world, libgdx crashes on phone

Android Libgx Frogger game crashing: Could not find class 'com.rengelbert.froggergdx.FroggerGame'

My main diffrence between all the other questions is that I did not create the android project when I created the desktop project which I create with the Gdx-setup.jar. I decided to make an android project quite a bit after I created the desktop version.

I am getting the error:

As you can see the error is that

Could not find class 'com.cvgstudios.pokemonchrome.ChromeGame', referenced from method com.cvgstudios.pokemonchrome.RunAndroidChrome.onCreate

While looking around to find the answer to my dilema a possible solution was to make sure it was exporting the main project properly. I fixed that:

Android Project exporting the main project

However the problem still persists.

I've checked everything all of the order and export boxes, in desktop, main and android project's buildpaths.

This is my class

import android.os.Bundle;

import com.badlogic.gdx.Gdx;
import com.badlogic.gdx.backends.android.AndroidApplication;
import com.badlogic.gdx.backends.android.AndroidApplicationConfiguration;

public class RunAndroidChrome extends AndroidApplication {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        AndroidApplicationConfiguration cfg = new AndroidApplicationConfiguration();
        cfg.useGL20 = true;

        Gdx.app.log(ChromeGame.LOG,
                "Attempting to make Android Chrome Work");
        initialize(new com.cvgstudios.pokemonchrome.ChromeGame(), cfg);
    }
}

Post your RunAndroidChrome class... – Hariharan Aug 23 '13 at 10:09 — Hariharan, Aug 23 '13 at 10:09

There is an import missing in your Class RunAndroidChrome

import com.cvgstudios.pokemonchrome.ChromeGame;

Usually the IDE automatically import the depended Class.

If that is not a class defined by you, then the you must have forgot to Add Build Path.. Look here for how to add Build Path.

One another possibility is that you might have tested that in a wrong machine.

Also in cfg.useGL20 = true; we tell Android to use OpenGL ES 2. This means we will be able to test it only on a device as the emulator does not support OpenGL ES 2. In case there is a problem with it, switch this to false.
