I want to be an "expert"....

Hi everyone! the purpose of this post is because I have a question about kotlin and java, recently I had a interview about deep tech in java and kotlin, as threads, co-routines and almost how java and kotlin works, so, please, someone can recomend me a book, online course or posts or all of that to be a "expert" in those programing languajes in android?, I really love to do apps but if I just know the superficial concepts to do good apps I never know about how to handle deep problems in memory, garbage, threads, synchronized, etc.

I hope someone can recomend me something.
Thanks!

I totally recommend whatever Android books Ray Wenderlich has released, most specifically:

• Kotlin apprentice
• Android apprentice
• Data Structures and Algorithms in Kotlin
• Kotlin Coroutines

and a bonus would be:

• Advanced Android App Architecture (Kotlin)
• Android Test-Driven Development

Hope this helps... I went through the same equivalent books on iOS development which is my strongest now and they helped me a lot! I got the same books for android and I'm planning on learning it using that specific order
