@mzimmers perhaps you run into this: https://forum.qt.io/post/785169
This definitely helps. Combined with regenerating the android files, and deleting the build directory, I'm past that error. (I'm onto another error, but I think this is my doing. I'm posting the relevant output here.)

So:
- delete the build directory
- clear your Qt Creator cache
- use Creator to generate but NOT modify AndroidManifest.xml
appears to be a successful procedure, if my above assumption about my project restructuring is true. I'll do some more experimentation and report back.
Oh, I tried 12.0.2...no improvement. Thanks for the link, though.

@ekkescorner @JoeCFD thanks for the suggestions.
After fixing the problem in my project structure, I am now able to load the program through Creator, sometimes. Sometimes I get the original error. I am also able to load the .apk from the command line (outside of Creator), so I'm reasonably confident the problem isn't in how my .apk is built.
I'm trying to ascertain why I'm still having only intermittent success with Creator. When I can determine a reliable procedure, I'll post it here.

Hi all - I need to return my attention to this -- I've got to get this working.
All my build setup items seem in place, and the project builds for Android just fine. But when I try to deploy and run, I get this same old error message:
Activity Manager threw the error: Error type 3 Error: Activity class {org.qtproject.example/org.qtproject.qt.android.bindings.QtActivity} does not exist.Can anyone give me an idea what's going wrong here? Thanks...

what's your actual environment ?
Qt version, QtCreator Version
JDK, NDK, Java API
QMake or CMake -
- Qt 6.5.3
- Qt Creator 14.0.1
- SDK Version: 12.0
- NDK Version: 25.1.8937393
- JDK 17
- Using CMake
- Windows 11
Not sure what you mean by Java API, but maybe this will help:

@ekkescorner I've created the templates, but I haven't modified them. I can't find documentation that tells me how to populate the fields.
Note that the pulldowns for setting the SDK are disabled. -

Google has changed this long time ago. Now Min and Target are managed by Gradle and not the Manifest.
here's some info from my blogs HowTo do this with CMake:

As a quick sanity check, create a new "Hello World" project. Does that build and run correctly?

@JKSH OK, built a new project. I configured it for Android, but there's nothing in the CMakeLists.txt file about Android. (I didn't add any of the stuff that @ekkescorner mentions on his web page.) When I build, I get an error:
:-1: error: aapt2.exe E 08-18 19:22:13 16988 23404 ApkAssets.cpp:149] Failed to load resources table in APK 'C:\Users\michael.zimmers\AppData\Local\Android\Sdk\platforms\android-35\android.jar'. error: failed to load include path C:\Users\michael.zimmers\AppData\Local\Android\Sdk\platforms\android-35\android.jar. * Try: > Run with --stacktrace option to get the stack trace. > Run with --info or --debug option to get more log output. > Run with --scan to get full insights. * Get more help at https://help.gradle.orgSo, I'm not sure where to go from here. It's hard to tell whether the problem is in my Android setup, or my specific project settings.

@mzimmers running Qt Examples without changes this should work without creating and modifying templates.
If examples don't run there seems to be something wrong with your Android / QtC installation
BTW: you can verify the settings for min and target. go to your build dir and take a look atbuild android-build gradle.properties -
@ekkescorner just to be clear, this error didn't come from one of the presupplied Qt examples. I created it using the project wizard.
Here are the version settings in my gradle.properties file:
androidBuildToolsVersion=33.0.0 androidCompileSdkVersion=android-35 androidNdkVersion=25.1.8937393 qtMinSdkVersion=23 qtTargetAbiList=arm64-v8a qtTargetSdkVersion=31They don't seem to match what you indicated would be correct.
BTW: Is there a typo in this section of your page?
Qt supports these API Level: Qt 6.6: Min API 26 (Android 8) Qt 6.8 MIn API 28 (Android 9) see QTBUG-124890 Qt 6.6: Target API 33 (Android 13) Qt 6.7: Target API 34 (Android 14) -
this is from one of my 6.7.1 apps:
android.useAndroidX=true androidBuildToolsVersion=34.0.0 androidCompileSdkVersion=android-34 androidNdkVersion=26.1.10909125 qtMinSdkVersion=26 qtTargetAbiList=arm64-v8a qtTargetSdkVersion=34QMake or CMake - always the same for my projects
BTW: some examples from create (update) Templates I did:
https://ekkesapps.wordpress.com/qt-6-cmake/qtcreator-android-templates-2/ -
OK, but...given that this file is built for me, clearly I don't want to just make changes to it. Where are the settings that populate the contents of this file when it's built? Is there something wrong with my Preferences -> Devices -> Android settings?

don't know what's wrong
seems you have built with android-35
dont know if this works with 6.5
have no experiences with 6.5 - started my Qt 6 development with 6.6
you can try to change this to 33, what's supported by 6.5 -
@ekkescorner I changed to 33; no success. I then deleted all my Qt project cache and rebuilt. It now works...sort of. I'm going to have a bunch more questions, but it's time to close out this thread and start a new one. Thank you for all the help.

this is always the first thing if something wrong with build or if templates created or QtC changed: delete the build dir physically - not only build-clean in QtC
sorry - forgot to ask you about ;-)

good that it's working@ekkescorner just to be clear, for me it was not sufficient to delete the build directory. I had to go into home\AppData\Roaming\QtProject and delete all the files in there.
-
this is the folder where QtC stores Settings on windows ?
I never use the default settings location for QtC to avoid problems if different QtC versions are installed. I always start QtC with a specific settings folder for each installation.
