Libgdx throws an exception to the helloworld application when run in the emulator

Question

I followed the tutorial at http://www.youtube.com/watch?v=vLx_72qxK_0&feature=player_embedded and created a simple libgdx library application that makes the application with a red background.

This works fine when I run it as a standalone desktop application, but when I launch the -android version, an exception is thrown and the application does not start.

Does anyone have any experience with this library?

Answer 1

fixed the problem by making sure that the armeabi and armeabi-v7a files are in the / libs of the Android project.

Answer 2

I found that the problem was caused by an attempt to run on an Android Android with an Intel Atom x86 image. I believe you need to use an ARM image.

Answer 3

Source: How to import x86 folders for Android (July 2013)

The developers told us that they skipped the missing x86 folder on the last night, so you should not use the ARM emulator.

So, download the last night below and copy the x86 folder to the libs/ folder of the project / library project (where you will also find the armeabi and armeabi-v7a )

Last night for libgdx containing the x86 folder to host in libs /

This solved the problem for me.
