Android app crashing at startup

Creaperdown

I am trying to bring my desktop application to Android. I managed to get it to build and run, but it crashes on startup. I get the following Application Output:

I am not able to see what causes the crash here, does someone have an idea?

@Creaperdown Debugger could provide more hints

@Creaperdown we can't help you with that remotely.

I once had an issue where moving from gcc to clang exposed a bug (in printf usage!) which clang aborted on.
As such it crashed on android and not on desktop.

So, keep an open mind and figure out what is going on the hard way :)

@TomZ I think this might be more precise: https://forum.qt.io/topic/152468/1-warning-warning-qml-import-could-not-be-resolved-in-any-of-the-import-paths-x

@Creaperdown you're trying to do network stuff, is your manifest file correctly setup and do you do runtime permission requests before accessing any related functionality ?
