My app says “invalid Qt version” on my Android device (Qt 5.9.1, Android 5.0.2)

Linuxx

When I'm trying to create a basic application using Qt with dynamic linking through ministro,
I getting error invalid qt version https://i.stack.imgur.com/JQniW.png
I use:

qt-opensource-linux-x64-5.9.1.run
android-ndk-r15b-linux-x86_64 android-
sdk https://i.stack.imgur.com/GZ1zs.png
fully updated debian.
phone zte blade with android 5.0.2

I searched for solutions unsuccessfully on google.pl.

Building applications with Qt libraries appended to apk was successful, but I want to release an Android application based on the GPLV3 license with no hassle of installation.

@Linuxx Ministo doesn't work for Android 5+
see http://doc.qt.io/qtcreator/creator-deploying-android.html
Android 5 devices only support Creating Distributable APK Packages

So there is no option to create and publish an android application without buying a license for qt? Even making it available as an open source?

Just choose option of bundle at libraries with apk.
You can get this option in project settings-deployment. Don't depend on ministro tool. Users generally don't prefer downloading after installing apk

you should read this about Open Source and Android and Licensing:

of course easiest way is to buy a commercial license. There's a special price for start ups and independent devs:

from my POV it's worth the price - Qt is the best for x-platform mobile APP development - esp. since QtQuickControls2 provide all the Material styled Controls and easy navigation
