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.

Any library you would like to recommend to others as it helps you a lot? For me, mapstruct is one of them. Hopefully I would hear some other nice libraries I never try.
JavaCPP and presets for working with JNI
-
JDK 19 released
In the meantime you might want to check out JavaCPP: https://github.com/bytedeco/javacpp
-
How can I use K/N with C++?
Maybe you can use JavaCPP?
-
Does Java 18 finally have a better alternative to JNI?
Here is the code for JNI, which uses the prebuilt JavaCPP library to call the getpid function. We don't have to write all the manual C binding code and rituals as the JavaCPP library already does it.

Javacpp is the best ffi library of all https://github.com/bytedeco/javacpp

If it gets better w age, will java become compatible for machine learning and data science?
As for our approach, we maintain a library called javacpp: https://github.com/bytedeco/javacpp which proves a python wheel like experience where we distribute natively optimized c/c++ code (and even cuda accelerated code) as jar files on maven central. We also are able to develop with a python like experience by passing pointers around and other low level constructs directly allowing optimizations that you typically only get in c/c++.

CXX - Safe interop between Rust and C++
https://github.com/bytedeco/javacpp
* it maps naturally and efficiently many common features afforded by the C++ language and often considered problematic, including overloaded operators, class and function templates, callbacks through function pointers, function objects (aka functors), virtual functions and member function pointers, nested struct definitions, variable length arguments, nested namespaces, large data structures containing arbitrary cycles, virtual and multiple inheritance, passing/returning by value/reference/string/vector, anonymous unions, bit fields, exceptions, destructors and shared or unique pointers (via either try-with-resources or garbage collection), and documentation comments*

An article on how to use C++ for cross-platform development
I did not try myself, but for JNI maybe this could make lives easier? https://github.com/bytedeco/javacpp

Resources for learning Android NDK?
Best you can do is refer to the official samples and learn by taking one of the samples and modifying it to your use case. The comments in the samples should be quite adequate.
-
Can C++ be used to develop android apps? If not what is it's best alternative?
You can compile c++ for android using the NDK.
-
CPP Mobile development
Mobile has a lot of C++ as libraries but in https://developer.android.com/ndk for android.
- But guys, if you had to choose?.....
-
Does anyone else think Android should allow C++ natively and not just through NDK and JNI?
Then please provide references that say how to do this. Here https://developer.android.com/ndk it says:
-
How can I use K/N with C++?
cinterop is only for Kotlin/Native, where the whole application gets compiled to native code. If the target is Android, you want to use Native Development Kit (https://developer.android.com/ndk) instead.

Build Android apps without an Android SDK using PicoLisp
It's a little convoluted since the app does still fork from the zygote with ART in there, but they added an entire layer of APIs so you can jump right in from C++. Here's a sample https://github.com/android/ndk-samples/blob/master/native-ac...
What are some alternatives?
