    Enforce ConstraintTracker#setState is on the main thread.
   
    - setState now asserts that we are on the main thread
    - Moved assert*Thread methods into their own utils
    - Annotated several tests manually calling onBroadcastReceive
      as @UiThreadTest as our broadcast receivers only operate on
      the main thread (they use the default registerReceiver
      method)
    - NetworkCallbacks are invoked on non-main threads by default;
      in this case, we re-post them to the main thread
   
    This is part of the solution to a concurrency exception in
    ConstraintTracker.

Fixed in https://android-review.googlesource.com/c/platform/frameworks/support/+/728180 (not sure why the automated message isn't being shown here).  This should be available in alpha07.

Which Android API version is this?

It's happening 100% on API 24

Do you mind attaching a logcat and a sample of your code?

I'm unable to reproduce this crash in my dev device. It's happening in out prod build. I've attached the crash log here - Not really sure how helpful that can be
https://gist.github.com/supreethprakash/01bc952ab80eba2d9f2478070cba627f

Our code is not in play here, it could be happening when some scheduled job is about to run

commit 56776a6d2eddef14d8275828f665df1177d52ac6

    Speculative fix for IAE on NVIDIA Shield tablets.
   
    We can't reproduce this on other devices, but Shield Tablets on
    API 24 can return an IllegalArgumentException for some reason.
    Since this isn't something that is fatal to WorkManager, we
    will catch the exception and move on safely.
   
    Bug: 119484416
    Test: Ran existing tests.
