Migrate Android Module to Standalone Library I built an Android app and spent a lot of time creating an api/network layer. Having invested quite a lot of time on this, I wanted to make this module its own library. I have found some solutions to import and export modules between android projects and making them into AAR's however what I am most interested in is using this in our java/kotlin based microservices. Hundreds of endpoints later I went to build a microservice and realized i needed to re-create this entire layer instead of...

Cannot find any explanations on how to write custom MongoDB queries in Kotlin with Spring Data except using this method.

Function don't exit with return kotlin I wrote this function with recursion in Kotlin, it's just for academic purposes. But I have a problem, when the condition is true, the execution is not interrupted. It's as if it ignores the return command and keeps iterating. I have seen it in debug, that when the condition is true it goes through there and then continues. Anyone knows how to solve this? In this capture, see the debugger in the return true statement, but the function don't exit. <a href=""...

Also I wouldn't like to hide the pointer completely on the OS but rather only when the app is running. I couldn't...

I have a function that assembles a URL with GET parameters, and it takes a parameter name of type String and currently a parameter value of type Any? on which it calls toString() if not null. I want it to work only for types which can be meaningfully put into a URL (numbers, strings and booleans), and prevent people from calling it with any other object type. Is this possible in Kotlin? The usecase is that I tend to forget converting units to numbers when calling this function, and end up...
