Make an Android app on one machine and edit the package name in the manifest and then commit this to a repository.

Then try checking it out in a different location and open it in Qt Creator.

You will get the message "Android files updated automatically", and if you do a diff on the repository, you'll see that the package name has been broken:

-<manifest android:versionCode="1" package="org.qtproject.example.QtDemo" xmlns:android="http://schemas.android.com/apk/res/android" android:versionName="1.0">
+<manifest android:versionCode="1" android:versionName="1.0" package="org.qtproject.example.QtDemo.QtDemo" xmlns:android="http://schemas.android.com/apk/res/android">
