Unable to debug Android App (Windows + Qt Creator 12 + LLDB)

woaaah.... on one occasion we caught a single breakpoint.... with all the sigfaults flying by... same as on Windows

Now, it's on latest Ubuntu

So we are now running both Linux and Windows 11.
We are having mobile devices from multiple brands targeting API 31.
The problem is reproducible with QT sample apps.
anyone? QT?
- Qt 5.15.16
- QT Creator 12 (the online installer does NOT give us access to older builds)
- evaluated both GDB and LLDB both local and remote
- attempting to debug Qt official Clock sample app
- we've tried targeting 32 and 64bit ABIs
These are all brand new fresh installations of Windows 11 and Ubuntu.

By the way, can anyone tell me why API 31 ABI Clang compilers are missing?

All segmentation faults appear on 4 distinct Android 13-14 devices I've tried.
On android 10 there are no segmentation faults. BUT debugging either does not work at all in most cases OR why by chance when it kick-in at all then this happens after a delay lasting minutes after the app has long launched and been executing code. ONCE today it happened that a breakpoint hit fist line in main FIRST time in a week and that happened on Android 10.

Having read through this thread, I must say: Sorry! I understand your frustration and feel your pain.
This issue is a bug, and not related to a local configuration problem. Thanks a lot for your patience and effort in trying alternatives and troubleshooting.I have been observing and reproducing Qt Creator landing in the disassembler since November 2023. Rremote debugging on Android is complex - I haven't been able to pin it to a specific reason. This needs more attention, I fully agree. I'll channel it internally and keep you posted.
I trust you understand that this is not a trivial matter. It may take a little while, until it's nailed down and solved.

Plain and simple - on which configuration would 5.15.16 debugging work with an Android device.
We would buy and invest into the VERY EXACT configuration.
Exact mobile device/ OS, PC setup, QT Version.
We would also pay for the hint to anyone who provides an effective solution. Payment today.

Axel, thank you yet still - we've got a client base which expects us to have the development rolling.
Kindly please advise on what configuration we would be able to use 5.15.16 with an Android setup, we would just like to be able to debug.
If we wouldn't be able to have 5.15.16 working then kindly PLEASE advise which QT version in the 5.X branch to use.
I'm having one developer rolling back to QTC 11 without avail through QTC 10,. he's now o QTC8
We would like to use Qt 5.15.16 with all the bug fixes, the very reason why we bought into QT commercial license to begin with, is that possible?
Please. Thank you so much -

Are you / is Qt able to provide us with a working VM/ docker image on which debugging with Qt 5.15.16 would work. Or is that asking too much?We can pay. Money is NOT an issue.

when considering debugging from Apple M2? -
so since Android SDK with API 31 EMPLOYS Java class version 61 objects for its components this IMPLIES a requirements for JDK version 17.
QT ... kindly update your docs?

Please note that Qt has an actual jira bugtracker. https://bugreports.qt.io/ I expect that direct actionable issues you find are better traceable there.

you might want to contact kdab.com with such questions. I think they have the most expertise in such matters. And they are simply a commercial company so it should be a relatively simple question to get such a service.
