Qt6.5 Android What Problem.. Debug Mode
-
QT : 6.5
Crator : 9.0.2Qt Kits
Android SDK, NDK JDK Version
Emulator Warning
Error
Make Source Code
I am using Qt 6.5 version and Creator 9.0.2 version. How can I resolve Emulator warnings and errors? I have been searching for solutions on Google for three days without success. Can you please help me? Thank you so much in advance.

Thank you for your response.
Since this is my first time using Qt for Android, should I download the adb.exe file again from the SDK Manager? If not, I apologize, but is it possible to receive C++ implementation example files?I want Study and Setting Qt android!..

OK, do I understand correctly: Android simulator and the kits mentioned in the screenshots have been installed on the system. Getting the Android emulator up and running hasn't succeeded at all - so far.I assume, the instructions here and here have been followed.
What may be a bit misleading in the documentation pages linked above: The list of supported devices mentions, that they are supported with the architectures armv7 and arm64_v8a. If you are working with an emulator, this list can make you believe, that you have to install an emulator with one of those architectures and let it emulate one of the devices from the list. The screenshots indicate, that this is what has happened on your system. It's actually wrong. Always install an emulator matching the host system's architecture: x86_64 in your case. Any other emulator will work with full hardware abstraction, which makes it extremely slow.
So let's return to the error message.
=> Issue number 1: Lack of speed.
Solution: Remove the am64_v8a emulator and install one for x86_64. That gets you rid of the "seriousperformance" problems.=> Issue number 2:
adb.exe
The error message says it's obsolete, which I would interpret as "Neither necessary, nor used, but existing anyway".
That sounds like a misleading error message to me.
A possible explanation is: It timed out without having finished, whatever it was supposed to do.IMHO it's not worth investigating number 2 any further. Solving number 1 will uninstall this emulator with its
adb.exeanyway, to replace it with the x86_64 version. Let's hope that number 2 disappears by itself.Let us know, if it worked out.

The available compile kits look like the host system is x86_64.
The emulator reporting "seriousperformance" problems, emulates arm64 on x86_64. That's likely to be the reason for the slowness. I wonder how adb.exe can be obsolete. Maybe that's just a fixed part of the error message.That said, please try if using the Android 6.5.0 Clang x86_64 kit delivers better performance. I use arm architectures only on physical devices. Last time I tried armeabi-v7a (4 weeks ago), the latest emulator version was broken

After changing the architecture to x86_64, it worked.
ADB.exe Error ignored.
Thank you for answer!But there is another problem.. Please see the image below..
When I debug like the image above, the problem occurred.
How can I solve this? -
