Could you recommend any book and topic to me?

Question

Do you know any book to learn how to programme as an expert in Android? I've read A. programming to begginers, but I want more.
Despite the fact that I know the basic, I'd want to learn sql and how it works with android.
Thanks you.

Answer 1

I would recommend to inhance your java skills and it will help to build much more difficult applications. Plus it would be great if you read more about open - source libraries like butterknife, dagger, Rx java, retrofit, glide/picasa and much more. Knowing them will help you in building Android App. Try to follow the updates because what's good today may be depreciated tommorow.
