When distributing qt on android you can simply write an guide on how to decompile the apk, replace the qt .so and compile it again. I haven't done it yet so I'm not 100% sure about this. Also you could simply install ministro for this. https://doc.qt.io/qtcreator/creator-deploying-android.html
I had so many linking issues because of the Qt so on Android that I finally had to statically compile the run some tests at all, and in consequence to replace Qt with something else to avoid royalties. The problem of "DLL hell" (i.e. symbol conflicts between library versions) is well known on Android.
