使用 SyncAdapter 的 java.lang.VerifyError

Question

我正在使用本教程开发一个应用程序:http://udinic.wordpress.com/2013/07/24/write-your-own-android-sync-adapter/以及此存储库中的代码:https://github.com/Udinic/SyncAdapter .

但是当我尝试触发同步过程时，我收到 java.lang.VerifyError。

我发现没有任何解决方案对我有用。我很乐意提供任何建议!

在某个地方，也许在 onPerformSync() 中，您的代码正在引用 OperationCanceledException。该类仅存在于 API 级别 16+ 上，您似乎正在尝试在较旧的 Android 设备上使用它。
