Hi,
I can't deploy any app to Android.
Compile log:

Skipping createRCC
adb server version (39) doesn't match this client (41); killing...
* daemon started successfully
Installing Android package to device.
Running command "C:/AndroidSDK/platform-tools/adb.exe -s ce12182c5a102118037e  install -r C:/temptrier/build-WriteableLocationQuickTest-Android_Qt_5_15_2_Clang_Multi_Abi-Debug/android-build//build/outputs/apk/debug/android-build-debug.apk"

11:31:07: The process "C:\Qt\5.15.2\android\bin\androiddeployqt.exe" exited with code 16.

Interesting could be the double slash in the apk path. I've read about that in a few posts - but never seen a solution. Windows Explorer wouldn't take that as a valid path. I don't know where I can influence the path's building.

Here my Android settings:

Creator 5.02
Qt 5.15.2 (complete reinstall didn't help)
Win10-64
targeting API 30

Thanks for any ideas!

Hey, can nobody give me a hint on this one? It doesn´t even work with a new QML project. I cannot develop on my laptop. That's a problem right now, as I am going on family vacation and have to finish a few things from abroad...

Solved. I have found a Splashtop Wired XDisplay Agent using a different adb version. Had to deactivate it, because it restarted adb quicker than Qt could handle the problem.
