Qt based android application is crashing during startup on one specific device. "dlopen failed: libqtforandroid"

Question

My application is crashing during startup only on one specific device: Huawei Tablet AGS2-W09. Qt 5.12.3.

I have a logcat dump from device:

07-01 10:53:09.327  6135  6156 E AndroidRuntime: java.lang.UnsatisfiedLinkError: dlopen failed: file offset for the library "/data/data/pl.domain.appname/qt-reserved-files/plugins/platforms/android/libqtforandroid.so" >= file size: 0 >= 0

What could I do next to find the problem?

Answer 1

Problem solved. If you are running into similar problem, it's because you are trying to run 32bit application on 64 bit device. Qt is not yet supporting AAB, so you need to compile 32 bit (armeabi v7a), and 64 bit (armeabi v8a) separately.
