    @mzimmers probably, you also have deleted your build dir ?
    and uninstalled old app and rebooted android device ?

      @ekkescorner I did delete my build directory, and uninstalled the old version of the app. I didn't reboot my device, but I can do that. I'm not sure that will help, though, as I believe this error is occurring before Creator attempts to communicate with my tablet.

      EDIT:

      I restarted my tablet, and get the same error.
      Doesn't this appear that it has something to do with the entry in the manifest file? Or...should that get regenerated automatically?

        @mzimmers have no idea. you're using the default QtActivity.
        the packageName must be unique for your app and will be used as applicationId
        should be all ok with your app
        curious
        BTW: have only did such things (renaming) with QMake yet

          @mzimmers Can you check your java code path if it starts with your project name under android/src?

                @JoeCFD there's no Java code in my project source, if that's what you mean.

                  @mzimmers OK, you do not have any java class in your project. Look through the whole project for your old project name.

                    @JoeCFD can't find a thing.

                    I regenerated the templates, and now am getting a build error:

                    > Failed to apply plugin 'com.android.internal.version-check'.
                       > Minimum supported Gradle version is 7.5. Current version is 7.4.2.
                    

                    Didn't Gradle get installed for me when I chose the Android option in the Qt installer? I'm wondering how I should go about updating it.

                    EDIT: apparently changing this line:

                    distributionUrl=https\://services.gradle.org/distributions/gradle-7.5-all.zip
                    

                    in the gradle-wrapper.properties resolved that issue. I copied back my manifest file, and am back to the original issue:

                    Activity Manager threw the error: Error type 3
                    Error: Activity class {nga.demo/org.qtproject.qt.android.bindings.QtActivity} does not exist.
                    

                    So, I'm back to my original question: what should I change this line to?

                    <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="nga.demo" android:installLocation="auto" android:versionCode="1" android:versionName="1.0.2">

                      @mzimmers No, Qt installer does not do it as I remember. There is a place you can change gradle version number in the installed Qt.
                      You are using Java 18? from here:
                      https://docs.gradle.org/current/userguide/compatibility.html

                      Even the latest Android 14(API 34) requires only Java 17. Scroll down from here:
                      https://developer.android.com/build/jdks

                      You can try to set
                      package="org.nga.appyyy"
                      if nga is your company name and appyy your project name.
                      That is the format I use. I saw someone wrote org seems needed. We need to document this in the forum somewhere. We waste so much time for this kind of issues.

                        @JoeCFD well, as it turns out, it doesn't appear to be related to my changing the project name -- I had an old copy of the project, and that fails in the same way. (It had been awhile since I bothered trying to load to the tablet.)

                        I'm going to re-title this topic, as the current title is incorrect.

                          and Android target API ?

                              @mzimmers arm64-v8a is the architecture - in this case arm 64bit
                              in QMake:
                              under Build Android APK Android Build Platform SDK is set to android-33 (Android 13), Android Build Tools are 33.0.2
                              and in .pro I have set Min SDK and target SDK:
                              ANDROID_MIN_SDK_VERSION = "23"
                              ANDROID_TARGET_SDK_VERSION = "33"
                              For me - working on macOS - I never have to install Gradle or so. it's working.
                              I always do 'Create Templates' as you have done. Sometimes I had problems creating templates and 'Replace all' - have done 'replace' for each file extra.
                              I'm using Qt 6.6 and QtC 11.0.2
                              Have no idea how this will be with CMake. Just fighting with my last 5.15 App-port to 6.6 (QMake), so soon will enter CMake ;-)

                              BTW: as @JoeCFD said: as packageName you should use your domain in reverse order together with a short app name, per ex. org.yourname.yourAppName and this must be unique. the packageName is independent from project name, per ex for a customer I'm building APKs with different packageNames like: de.theCustomer.theApp.test and de.theCustomer.theApp.prod while the project has a different name: theCustomer_theApp

                                  Hi all -

                                  I need to bump this, because I really need to get this app running on Android. I created a new, minimal project, and I'm still getting the error:

                                  Error: Activity class {org.qtproject.example.minimal_map/org.qtproject.qt.android.bindings.QtActivity} does not exist.
                                  

                                  I'm guessing it has something to do with my manifest file, and here's where I need help. I really don't understand most of the fields in this display:
                                  Screenshot 2023-12-26 141909.png
                                  So, a few questions:

                                  1. the fields that look like: -- %%INSERT_APP_NAME%% --; am I supposed to replaceeverything with my own values, or do I keep the dashes and "%"?
                                  2. do I need to replace all of those fields?
                                  3. what exactly is an "activity name?" My searches haven't revealed much.

                                  Thanks for any assistance...

                                    if you don't replace the values, then QtCreator will fill this value. After building the project, you can go to the build dir, find the manifest and open to see what vaklues QtC inserted.
                                    In my apps I always put my own value in, per ex. QtWS for the QtWorldSummit App.
                                    if you change the value, switch editor to xml source to see that Application label (https://developer.android.com/guide/topics/manifest/application-element#label) and Activity label (https://developer.android.com/guide/topics/manifest/activity-element#label) changed.

                                    what exactly is an "activity name?" My searches haven't revealed much.
                                    see above. simply search for "android manifest doc"

                                      Quick sanity check: Do you get the error if create a new, minimal project and run it on Android without doing anything at all to the manifest file? In other words, just create the project and build + run it.

                                        also have noticed that opening with Manifest Editor sometimes changes the content. But in my cases it was only a reformatting / reordering and nothing destroyed. (QtC 12.0.1)

                                        BTW: I'm getting best experiences this way:

                                        • Update Templates
                                        • check changes (using git)
                                        • add / replace with my settings
