RenderScript Support Library crashes on x86 devices

Question

I'm getting FATAL EXCEPTION running android.support.v8.renderscript.* on Razor i, a x86 device. The problem goes away if I use android.renderscript.* Also there is not problem with ARM devices. Here is the exception:

Answer 1

I meet the same issue when I using Build Tools 21.1.1 and proguard, you may need to use the following proguard settings:

-keepclasseswithmembernames class * {
    native <methods>;
}
-keep class android.support.v8.renderscript.** { *; }

Answer 2

With Build Tools 21.1.1 this issue disappear.

Answer 3

I think you should also include the native libraries from \build-tools\19.0.2\renderscript\lib\packaged
