Qt Thread Issue with Android(?)

[Gourmet]

Hello. I am working on Qt5 app with similar feature - it uses Calendar Content Provider to access events. Please let me know - what was the problem and was it solved?

By the way - in my apps I met "suddenly asynchronous crashes" when I mixed UI Qt5 C++ code with QML views and Android Java functions. It always were not to be localized by simple code analysis. But I solved problem by manual using signal/slot QQueuedConnection-s between methods accessing to QML, C++ UI and C++ methods accessing Java functions. Direct connection forces receiving slot be executed in same thread as sending signal. Receiver cannot always be ready. But queued connection separates these threads and allows receiver process data when it is ready.
