You have also the opportunity to send a direct download link to your uploaded application file.

But that is often a huge pain, especially if you have no…

Live Templates can really make the life of us developers easier. These templates are a built-in tool within Android Studio that allows you to write pre-defined code snippets that let you add parameters while typing and are compatible with the IDEs auto-complete function (IntelliSense).

Therefore in this article, I want to share five of my favorite books about programming topics that in my opinion, every serious programmer should have read at least once.
