Correct detection of latest Android build-tools versions

^{Originally posted by marchbold July 21, 2021} When specifying an Android SDK via the -platformsdk option we are seeing the message

NOTE: Multiple Android build-tools folders exist, choosing the latest version (29.0.0 rc4) for packaging

Just wondering what process you are using for deciding the latest version, as it seems to change for different builds on my machine and is not the latest version I have installed?

eg I have all these installed in $ANDROID_HOME/build-tools, as you can see 29.0.0 is not the latest.

22.0.0
24.0.0
24.0.3
25.0.0
25.0.2
25.0.3
26.0.0
26.0.1
26.0.2
27.0.0
27.0.2
27.0.3
28.0.0
28.0.0-rc2
28.0.1
28.0.3
29.0.0
29.0.2
29.0.3
31.0.0

I keep getting the following error when I have build tools 31 installed. If I uninstall it everything works as should with 30, however this is not an option for me.

Is there a way to select manually which build tools to use?

This one again :-( > Installed Build Tools revision 31.0.0 is corrupted. Remove and install again using the SDK Manager.

This is related to the fact that the gradle plug-in - and gradle version - that we're using here is unable to cope with the build-tools that don't contain a "dx.jar" tool.

To avoid AIR looking at particular build tool folders, you can make them "hidden" (on Windows). Ideally we'd update everything so we would require people to have the latest Gradle/plugins versions installed (generally by keeping Android Studio up-to-date...)
