Most tutorials and how to's show you the basics of app building, but they don't show you how to use the latest technologies and libraries.
Most projects and jobs require you to know how to use the latest libraries. This is what this course is all about.

  • Dagger2 for dependency injection
  • Jetpack navigation for navigating the user through the app screens
  • Jetpack Data Binding for building UI screens
  • Glide for seamless image loading
  • Jetpack Palette for extracting colors from images
  • Unit tests to test the application and make it stable and robust
  • And we will build everything in Java
If you want to become an expert Android Developer, you need to know how to use these technologies.

This is my 3rd course from Catalin this month. I finished all 3. The first 2 I've given them 4.5 stars simply because there weren't comments in code but they could easily be 5 in any days.. This one I'm giving this 5 stars for being so prompt and kind in addressing the mistake for uploading the wrong video in one of the sections.

I recommend this video and his other videos as well in Android courses. Thank you!

I have enjoyed the course very much. I have been following all the courses but this course was covering all the points. I have applied the live data concept to one of my application based on this course topic and I am glad I am successful in delivering it . Thank you very much Catalin. I am looking forward for more courses . Thank you very much.
