I use it in my projects but when the renderscriptTargetApi was 19 had some error like

Error:(3) Error retrieving parent for item: No resource found that matches the given name 'android:TextAppearance.Material.Widget.Button.Inverse'.
Error:(18) Error retrieving parent for item: No resource found that matches the given name 'android:Widget.Material.Button.Colored'.
Error:Execution failed for task ':app:processDebugResources'.
> com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command '/Users/PPTing/Library/Android/sdk/build-tools/23.0.1/aapt'' finished with non-zero exit value 1

when i change renderscriptTargetApi to 21 it warn me
Warning:Renderscript support mode is not currently supported with renderscript target 21+
