java.lang.VerifyError using SyncAdapter

I'm developing an app using this tutorial: http://udinic.wordpress.com/2013/07/24/write-your-own-android-sync-adapter/ and code from this repository: https://github.com/Udinic/SyncAdapter.

But when I'm trying to trigger the sync process, I get java.lang.VerifyError.

No solution I've found so for worked for me. I will be happy for any advice!

Solution

  • Somewhere, perhaps in onPerformSync(), your code is referencing OperationCanceledException. That class only exists on API Level 16+, and you would appear to be trying to use it on an older Android device.
