Answer 1

Have you tried to use Build-Tools 23.0.3?

Also, try replace

ScriptC_color color = new ScriptC_color (mRS, getResources (), R.raw.color);

with

ScriptC_color color = new ScriptC_color (mRS);

Answer 2

you just have to add this line in proguard-rules.pro -

-keep class android.support.v8.renderscript.** {*;}

and remove this line- compile files('libs/renderscript-v8.jar')
