Using the Blurkit library, I'm getting a crash in onCreate. I'm using Android version 24, not sure if that matters. Partial stack trace below. What am I missing? Thanks in advance!

build.gradle

android {

    compileSdkVersion 24

    buildToolsVersion "24.0.3"



    defaultConfig {

        ...



        renderscriptTargetApi 24

        renderscriptSupportModeEnabled true

    }

}



dependencies {

    ...



    compile 'com.wonderkiln:blurkit:1.0.0'

}

And the crash:

I figured it out, it's a Proguard issue. Simply add the following to your proguard rules:

-dontwarn android.support.v8.renderscript.*

-keepclassmembers class android.support.v8.renderscript.RenderScript {

  native *** rsn*(...);

  native *** n*(...);

}

If you run into this issue after migrating to AndroidX, you need to adjust the ProGuard rules like this:

-dontwarn androidx.renderscript.*

-keepclassmembers class androidx.renderscript.RenderScript {

  native *** rsn*(...);

  native *** n*(...);

}
