Important: Please read the Qt Code of Conduct -

Do not run the application on a real device.

  • The application is written with Qt Quik 2.

    If you run an application on a real device using a creator, it works.
    If you move .APK to the device, and start from there, does not work.
    When you start a black screen appears, and then the application is closed.

    What could be the problem?

  • Moderators

    Are you sure you copy the right APK file?

  • I copy name-debug.apk.

    The program that creates a QtCreator on the device separately, too, does not start

  • Moderators

    OK, that sounds good.

    And which deployment method do you use (Ministro, bundling Qt libraries, storing Qt libs in temp location)? Any additional, external dependencies?

  • I use "bundling Qt libraries".

    also to the project added "google-play-services_lib" with help file "" which is located in the dir "android". It comes from the old versions so nobody touches

  • Now In the log is the content:

    W/System.err(25453): java.lang.ClassNotFoundException:

  • Moderators

    Hm, sorry, I don't know what is wrong here.

  • The problem was in the outdated files in directory android
