更新LibGDX后Android崩溃

Question

I'm trying to update to the latest LibGDX version 1.9.2 (I've been using an old version for quite a while) but after creating a new LibGDX project and running the default badlogic logo application it crashes on Android. I've created new LibGDX projects plenty of times with no problems, so something must be different now because it's not working this time. There are no errors in my project and the desktop project works fine, it just simply crashes when I try to run the Android project.

I created a new LibGDX project using the setup application and then went through the Eclipse setup process that I normally go through which has always worked before:

• Setup desktop run configuration to point the assets folder to the Android assets folder
• Configure Android build path, I've tried using both Android 4.4 (API 20) and Android 6.0 (API 23)
• Setup Android run configuration to use my Android project and launch on active devices

I've also tried using the SDK Manager to update the Android SDK's I have installed, re-downloading the LibGDX setup just in case it had gotten corrupted somehow, and deleting/re-creating the project several times but it still doesn't work.

I've also tried googling the error message but most of what I found seems unrelated to LibGDX. Some of the fixes I found were settings issues that are already set correctly in my project. So I'm kind of at a loss here and not sure what the problem is.

Here is the error message:

Answer 1

I ended up biting the bullet and installing Android Studio and the new version of LibGDX works fine with that. So I guess it's time to retire the outdated Eclipse + ADT plugin.
