For quite some time now, folks have asked if we could provide Android x86 builds of our native libraries. Today we granted that wish. The nightlies now come packaged with x86 Android binaries of our native libraries. This includes libgdx.so, as well as the natives of gdx-bullet, gdx-freetype and gdx-image. gdx-audio is currently only available for ARM, due to it using ARM assembly to speed up decoding.
To use the x86 natives, simply copy the x86/ folder from the nightlies to your Android project’s libs/ folder (next to the armeabi and armeabi-v7a folder). The setup-ui will not add those libraries for you automatically. I opted to do it this way for the time being as x86 Android devices are super rare, and you’d just blow up the size of your APK unnecessarily.
I also removed libandroidgl20.so. That contained our custom Android OpenGL ES 2.0 bindings. They are now directly compiled into the libgdx.so file.
