Sounds like you are at the beginning, skipping Java isn't a shortcut. Converting to Kotlin because you do not know Java could result it more QA in the process and longer development time. There are over 2000 Kotlin projects on Github, with everything from frameworks to build systems to libraries. Can you suggest me some video series/book/articles for learning amd understanding Java because now it seems like very complicated and unlogical language for me and other components of Android development seem much more logical to me.
