 I find it easiest to do final builds from the command line.

 If you get errors like "Your build is currently configured to use incompatible Java 21.0.4 and Gradle 7.3.3. Cannot sync the project." you'll need to update things.

 To fix, edit your build.gradle file and change the part that says:
+<code>
 id 'com.android.application' version '7.2.1' apply false
 id 'com.android.library' version '7.2.1' apply false
+</code>
 to:
+<code>
 id 'com.android.application' version '8.8.0' apply false
 id 'com.android.library' version '8.0.2' apply false

 Ok, that didn't fix the namespace error, to fix that, I had to add "namespace 'com.rtsoft.RTAndroidApp'" in the "android {" area, I just put it under the NDK version.  I know, this is all confusing and weird, you could look at RTBareBones's build.gradle file if need be.  For me it now build and played on the Android device fine.

+==== JAVA_HOME missing when running .bat files like BuildAndInstallDebug.bat ====
+To fix this you'll need to know where your java install is and set JAVA_HOME to it.
+Easiest thing is to use Android Studio’s bundled JDK, it’s usually located in a directory similar to:
+C:\Apps\androidstudio\jbr
+(Your path might be different; check your Android Studio settings under File > Project Structure > SDK Location or File > Settings > Build, Execution, Deployment > Build Tools > Gradle.)
+Open a Command Prompt and run:
+<code>
+set JAVA_HOME=C:\Apps\androidstudio\jbr
+</code>
+Then you can run the batch files in the same session and it should work.
+Or, to set it permenently:
+Right-click on This PC (or My Computer) and select Properties.
+Click on Advanced system settings.
+In the System Properties window, click on the Advanced tab, then click Environment Variables....
+Under System variables, click New... (or find JAVA_HOME if it already exists and click Edit...).
+Set the Variable name to JAVA_HOME and the Variable value to your JDK path (e.g., C:\Apps\androidstudio\jbr).
+Click OK to save the changes.
+Optionally, add %JAVA_HOME%\bin to your PATH variable if it isn’t already there.
+Verify the Setup:
+Open a new Command Prompt (to ensure the new environment variables are loaded).
+<code>
+echo %JAVA_HOME%
+</code>

   * If you get a weird "clang++: error: no such file or directory" linker error, it's possible your paths are just too long.  Even with the max path Win 11 fix I had this issue with one particularly huge fmod library path, so something to keep in mind.
