Download the latest Qt5.6.1 Android for Windows installer and install install android_armv7 binaries.
Compile and run example (it will be deployed to the device):
application window does not open. Instead there is a row with an application icon visible. If I try to open the example from the icon (that is visible on the main Android view) a black view is opened and then closed. So, it is not possible to open the texteditor example at all.
Same test result e.g. with \Examples\Qt-5.6\qtquickcontrols\quickcontrols\controls\basiclayouts example. Qt Creator log from the test run attached.
Note: bug cannot be reproduced on Linux & Mac.
