It is not possible to have multiple windows on Android. When you try to open/show a new window, it is drawn underneath the main one and the user cannot interact with it. The user can only press the Back button to "return" to the main window to be able to interact with that main window.

To reproduce the error, you can try the following example (from the ones installed with Qt 5.3 Beta): quick > window.

The problem exists on 5.2 as well.
