使用libGDX的Android应用崩溃

Question

I don't know what to do. I let libGDX setup an Eclipse project for Desktop and for Android and then tried to launch it on my Android tablet(I don't use an avd because it's awfully slow). Immediately after it installed the apk it tries to launch it and then the app crashes. I haven't modified any code of the project. It seems that when I launch the app on my Android device it can't find a class. Maybe someone can tell me what I have to do from the LogCat output.

If anyone here knows what's going wrong, I would be glad if they could help.

Answer 1

Have you copied all the native files like files with .so extension or other. Without this, your project will not run. Some classes must be dependent on that native files.

Answer 2

Are you using external Jars? These need to be in a libs (exactly written) folder or there classes will not be "dexed". If you are not using gradle to import the jar in your project you need to add it manually to include it in the build.
