Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Android Play Billing Needs updating
This was resolved in this issue: https://github.com/codenameone/CodenameOne/issues/3706

Backward Compatibility, Go 1.21, and Go 2
Naturally depends on the use case, yet they work good enough to be in business for 20 years.

Android 5 & 6 (only changed back into JIT/AOT due to long compile times), https://www.infoq.com/news/2014/07/art-runtime/
Unfortunely the best well known, Excelsior JET, is no longer in business, most likely due to GraalVM and OpenJ9 being available as free beer, while PTC, Aicas Codename One are safe in their domains.
There is also RoboVM (https://github.com/MobiVM/robovm) as free beer, however it actually started as a commercial product, and the acquisition from Xamarin kind of stagnated it (naturally).

Can't Reproduce a Bug?
At Codename One, we were using App Engine when our daily billing suddenly skyrocketed from a few dollars to hundreds. The potential cost was so high it threatened to bankrupt us within a month. Despite our best efforts, including educated guesses and fixing everything we could, we were never able to pinpoint the specific bug. Instead, we had to solve the problem through brute force.

Mobile Apps with Java
We don't use GraalVM since our project was developed prior to its existence and we aimed for deeper native integration than it can offer: https://github.com/codenameone/CodenameOne

Play Billing Library Version Deprecation
Thanks. It's always good to get another reminder. Yes, it was reported. u/shannah78 is working on this but we have time until November.

Problems compilint to android side

The Holy Grail of Java Performance
We use ParparVM which we wrote. It compiles a subset of Java 8 (sort of) to native by translating the bytecode to C and passing that through XCode. The reason we took this path and not the path of "direct to native", is that it allows for future compatibility.

Options for targeting ios with Java
I think libGDX still uses RoboVM, but I’m not sure if it’s being actively developed anymore.
-
Specific libraries java-flutter
For iOS the RoboVM project intends to be an AOT compiler for Java bytecode.
- Jetpack Compose announced for Web Development

Kotlin from zero with no previous programming experience
Kotlin is not ideal for iOS development afaik (maybe with RoboVM). With regards to Android development, it is perfect. For desktop applications it's good, there are always tradeoffs here. With regards to payment, I believe it is generally the case that you're paid more the harder the language is to learn (so C > C# > Python). This also affects how much people are looking for a certain kind of developer - there are more JS jobs than jobs requiring a C++ developer. Kotlin is a good choice to start though. It's not too complicated, it's not so simple that it's limiting you somehow, it's not too slow for most applications (+ it supports native somewhat) and it has a good environment with stable libraries you can rely on.
