I saw a lot of questions about how to start learning about Android programming and become a successful developer. Here I tried to cover most of the important aspects in Android Development.

Learning android development is a process that should go step by step. And this manual is no exception. No one can become a full-fledged Android developer in 30 days. This article will also present the best tutorials and articles on the development of Android.

Below are the topics that, in my opinion, are the most important for developing applications for Android:
