Workers on Android - permissions?

I can successfully utilize Workers in Flash CS6 when publishing for desktop 3.4

worker = WorkerDomain.current.createWorker(Workers.BackWorker);

The same code however when published for Android 3.4 or 3.5  or  Desktop 3.5   does Not work.

The worker is null.

I have heard others having issues with 3.5 so will let that go for now.

But how about Desktop 3.4  vs  Android 3.4 ?  Is there any permissions specific to workers that need to be included?

I have included the worker swf in the APK  and also tried Not including it.

Anyone have success at this?
