java.lang.IllegalStateException: Unable to create layer for X — when using hardware layers

问题

I'm using hardware layers on a custom view for better performance when animating its alpha. Seeing this crash on my crash reporter:

Fatal Exception: java.lang.IllegalStateException: Unable to create layer for X
   at android.os.MessageQueue.nativePollOnce(MessageQueue.java)
   at android.os.MessageQueue.next(MessageQueue.java:323)
   at android.os.Looper.loop(Looper.java:135)
   at android.app.ActivityThread.main(ActivityThread.java:5585)
   at java.lang.reflect.Method.invoke(Method.java)
   at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:730)
   at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:620)

My current workaround is waiting for this to happen, then storing a boolean for "device doesn't support hardware layers", and continuing with the crash that one time... then next time falling back to a simpler animation instead.

Given that this happens asynchronously, I can't really try-catch. Does anyone know of a way to check beforehand whether the operation would succeed, in order to use the fallback directly and not having to crash on the user even once?

Thanks!

Looks similar to https://issuetracker.google.com/issues/118714995. See if this helps.

Setting your parent view with View#forceHasOverlappingRendering(false).
