[Development] [Android] QML Qt.inputMethod.keyboardRectangle.height always equal to 0

[Ben Lau]

I think it is not implemented yet. There are few reported issues about
using virtual keyboard in Android.

*[#QTBUG-33713] Not possible to get boundaries of virtual keyboard on
android in order to align other stuff on it - Qt Bug Tracker*
*[#QTBUG-34089] Android: user input items filling the screen height won't
show well when keyboard is shown - Qt Bug Tracker*
*[#QTBUG-36027] Android: Support configuring software keyboard resizing
behavior - Qt Bug Tracker*
*[#QTBUG-34401] Qt on Android does not seem to respect
android:windowSoftInputMode in manifest - Qt Bug Tracker*
