Someone once sorted out the Top100 Java/Android projects on Github. As more and more Android projects began to switch to Kotlin, I would also like to sort out the excellent Kotlin/Android open source projects for better learning and reference.
The project selection process is simple:
- Search
android kotlinkeywords,Most starspress the star traffic ranking - Manual secondary screening, sifting out some face-to-face and e-book items
Best matchCorrection to avoid missing some low-star popular itemsTrendingUpdate the list from time to time and add popular items based on the author’s experience
The final results are as follows (the list will continue to be updated and maintained):
