It's going to be over this year, I've been transitioning from WPF to qt/qml this year, and I've been working on Android lately, and from my personal experience, whether it's QML or Android is similar to WPF in terms of framework and design, and the mobile side is designed for many reasons, Far from the desktop is delicate, complex, so if you master the idea of WPF and then engage in QML or Android development is very easy, of course, if the language is C C + + Java is a little different, but I think for a professional programmer to do the project has no threshold, skilled, Mastery will take time.
Here is a summary of my idea of starting the Android development, and will continue to update.
Android Four component activities (activity), service, broadcast receiver (broadcast receiver) content provider (contents Provider).
Activity can be understood as a form in WinForm
Fragment fragments can be understood as UserControl in WinForm.
View Android's control base class can be understood as WinForm
The four components used in the profile project of the Androidmanifest.xml Android project need to be registered here, and you can add permission declarations to the application.
