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

AFTER disabling

wait for debugger in Android Developer Settings (on mobile)
AND
after REMOVING the debugged application from the list of debugged applications ON ANDROID DEVICE

we are able to get have breakpoints working WAY SOONER (!!!)
now that i strange on the grounds of its own, is it not.....

but STILL unable to have breakpoints at main() stage working at all.

Yet again we are talking about QT Creator 12 + GDB + Qt 5.15.16 (LTS)

so the pressing issues are

get to know how to break as soon as in main() - normal thing to be expected
what the heck are sig-faults in Qt related code?

so seems like nobody (as usually) can assist around here even in questions regarding basic debugging.... this community is such a shame...

@CodesInChaoss Maybe try to do it on Linux and it could be easier. The executable is same.

A lot of lazy devs here ;-)

I'm especially interested in Qt because of its cross-platform ability. I do 90% of my android development in a native compile, with a window on my desktop. Have had maybe once or twice the wish to have a debugger for my remote Android device, but never found it important enough to install the tools for that. Qt Android tools are too freaking huge.

So, I'm lazy and debug on the native app on my desktop. Then do testing on the device, which rarely gives me issues I could not see on the desktop.

Not saying that what you want is wrong or anything like that. If QtCreator tells you that breakpoints should work, then they should work. And a paying customer should be able to demand attention from the Qt company.

I'm not a paying customer, no support for me.
Plenty of problems with the new Qt company of the last years, gerrit sucks. Jira even more so. As an open source programmer I have zero incentive to report bugs for the LTS releases since I'd wait at minimum a full year for a bugfix. And the quality is just really quite sad for Android. But it still is better than most alternatives I've tried. So here we are :-)

^------ what a F***** joke.... talked with a QT lady over phone today they ask for 3800 EURO a year (per seat) for a license with Technical Support

CodesInChaoss

the funniest thing of all is we've got an immense code base already so if we do not solve the issues above (LLDB - unable to debug at all) and GDB crashing all the time with all the other crazy shit going on - we would be FORCED to pay the above in HOPES they manage to give us some helpful hand.

Go figure.

CodesInChaoss

we're just too afraid they gonna say hey see - IT WORKS WITH A HELLO WORLD

CodesInChaoss

it all feels like there are some race condition issues or whatever...

it some times (on 3% of occasions) works PERFECTLY.

AFTER WE"VE INTRODUCE CUSTOM OVERRIDED TO SIG_FAULTS THROWN UPON US from QT.

as of now , as it is on current setup.

while on 97% of occasions it's UNUSABLE.

And that's a thing to worry about.

Creator dying every now and then... same for GDB... LLDB unusable.. breakpoints working on some occasions.. skipped other times...debugger kicking in late.....

it doesn't take a genius to notice that it's that's the case on QT Creator 12 with QT 5.15.16 on default settings and NDK/SDK installed by Creator itself, something is not right

CodesInChaoss

Go ahead and try setup QT Creator 12 and Android SDK on fresh Windows 11

Kits won't get created (..) openssl won't get downloaded. it's all messed up

CodesInChaoss

@CodesInChaoss

one of many examples on fresh windows install through online installer Commercial edition

JoeCFD

@CodesInChaoss did you click apply button after resetting.

CodesInChaoss

@JoeCFD yes as of now, we've deployed like 3 VMs already , we're diving into crazy things such as updating maveen, gradle, checking any binary dependancies, diving deep into the internals of GDB..... it does NOT work.

take a look at what official Android site says about debugging with GDB

CodesInChaoss

Let me emphasize - all was fine with QT 5.15.12 and OLD Creator 10 community edition over GDB.

CodesInChaoss

@CodesInChaoss

All the time while playing around with settings, while editing and saving QT Creator 12 would deploy new kits..... forgetting some settings... like the yellow triangle next to each is about missing compiler settings.. and of course.. it was set

Now we became paranoid to get things running

so we keep going through points available at https://wiki.qt.io/Qt_5.15_Tools_and_Versions

line by line... so we uninstall JAVA SE 17 compatible stuff in favor of JAVA SE 11 (even though in variety of places it says newer versions of JAVA are all good)

but guess what?

After the JDK is unistalled.... new versions of JDK chosen.... QT CReator 12... it would never recover - look above........
NEVER.

after one attempts to select NDK's loation by hand (..) wonderful huh?
