I have lots of libraries written in B4A. Each time I select "compile to library" in the menu, the compiled .jar file shows up again in the list of libraries that have to be jetified. Wouldn't it be an idea to automatically jetify the library whenever "compile to library" is chosen?
Not sure that it is worth the efforts... You almost never need to run the jetifier tool. Run it once when you install B4A v9.3 and then run it again only if you encounter a compilation issue related to android support classes (it will be very rare).
