Unable to debug Android App (Windows + Qt Creator 12 + LLDB)
-
I've triple checked that 'wait for debugger' is checked on my Android device.
- the app launches
- it shows a white bar that it's waiting for debugger to attach>
at this point in console it would say
I System.out: Debugger has connected I System.out: waiting for debugger to settle... I System.out: waiting for debugger to settle... I System.out: debugger detached?- the app KEEPS RUNNING for (5-10 seconds) after which it freezes.
- during that period NO BREAKPOINTS would ever be hit
- during that time Creator keeps showing that it's connecting.
- Creator would connect after 2-3 minutes.
At which point in console it would say
CONNECT: success adb://pbx4mn555hi7ojyx:5039 platform: remote-android TrueW AudioTrack: restartIfDisabled(304): releaseBuffer() track 0x7e628ce800 disabled due to previous underrun, restartingRunning latest Creator (commercial license). 5.15.16

It keep 'breaking' in some random looking ASM code. (but I know these are from lldb "android.os.perfdebug.PerfDebugMonitorImpl" for the most of it).
Now it doesn't even show the source file location.
It doesn't output any info, what kind of a signal caused this, nothing.How to proceed?
My breakpoints are hit as well.

I'll also give you one: no, I've enabled debugging on my TV and Fridge instead. -

What kind of conclusions do you have on mind the situation is depicted in detail already.

wrote on 20 Feb 2024, 09:56 last edited by@CodesInChaoss maybe you are using LLDB the wrong way with qt.
Also, have you checked if it is the right version for your Qt version?
How have you first of all added lldb in qt? which versiion of lldb are using? -

There are tickets in Bug-Reports saying that they've 'transitioned'.
I've always worked with GDB on WIndows with QT Creator, but to all my surprise, after installation of QT Creator 12 (we've transitioned to Commercial License) LLDB was selected and enabled BY DEFAULT on all kits.
So I said to myself, ok - let's go. I knew LLDB was for mac since that's what we've been using for iOS deployment.

Now, on windows , all kits deployed by QT Creator , by default have this:

The effect with GDB is that the app waits for debugger, the app runs (the breakpoints I set are not hit - in main())
yes yes, it works I'm not a noob, the app has been tested by thousands already.

These things do not come as part of the Online Installer.
