Exception happens when using RenderScript to create a blur image

Question

I want to create a blur image by using RenderScript but it crashes when the RenderScript rs = RenderScript.create(context); is called.

Here is the error log:

android.renderscript.RSRuntimeException: RenderScript code cache directory uninitialized

我建议您使用android support v8 renderscipt库来避免某些系统问题。
