android.support.v8.renderscript error on ProGuard

In any modern app that uses Renderscript, you should add the following to your proguard-rules.pro file.

# Render Script
-keep class android.support.v8.renderscript.** { *; }
-keep class androidx.renderscript.** { *; }

This will take care of apps that use the Android support library, as well as Android X.

Add to your proguard-rules.pro file line below:

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