This makes it possible for Qt applications to look native without Ministro, even though applications wishing to use services provided by Ministro will continue to do so. In other words, Qt Widgets applications will look native regardless of the deployment method; system wide or bundled Qt libraries.

Hi,

I'm using Qt 5.4.0, Qt Creator 3.3.0, and Nexus 5. If I create a "Qt Widgets Application" in Qt Creator, throw in a QPushButton on the form, and run the app, it uses the Android style. I didn't touch the default deployment method which is "Bundle Qt libraries in APK" by default, and I don't actually even have Ministro installed. I don't know what goes wrong with your app (tried uninstalling the app?) but I'd encourage to try such minimal test case first. It takes 10s to create the minimal app and it provides a nice clean plate. If that doesn't work, then we might have a bigger problem. I hope this is just some weirdness related to switching between the deployment methods and/or having old style extraction data around.

PS. The exceptions are unfortunate but harmless noise.
