Android Emulator does not launch LibGDX project?

Question

Whenever i try to execute the application on the emulator, the emulator displays an error saying "Unfortunately, My libGDX Game has stopped." The application runs fine in the desktop version though.

I have the latest nightly version, ADT version 18, latest GWT, and latest version of eclipse. My Android SDK tools is version 19, while my android SDK platform-tools is version 11.

Any ideas on how to fix this?

I was following along this tutorial: LibGDX tutorial

Here is a screenshot of what i see:

If this is an ARM based emulator, you forgot to add the armeabi and armeabi-v7a folders to your Android project's libs/ folder. Please follow the setup guide here: http://code.google.com/p/libgdx/wiki/ProjectSetupNew

Edit.- x86 is now supported

Answer 2

I had the same problem... Try Android Studio -> Run -> Run 'android'. In my case it worked. If still fails I recommend to re-install libG

Answer 3

If it doesn't work on the device either, try this: android-project -> properties -> java Build Path -> Order and Export. Then, click the project you've linked to (your plain java-project or desktop-project) and click the "Up"-button until it is at the very top. Make sure it's ticked [V]. I did that with the jars too, just in case, and now it runs on my device. I still get that same error on my x86 VM, because libgdx does not support x86 Android devices
