You might wonder what is the difference between package name we have in AndroidManifest.xml file and ApplicationId we see in build.gradle. They seem to be the same thing, but actually they are 2 different things. So if you didn’t know what is the difference between these 2 properties, you can find out now. ApplicationId represents
In this tutorial we will talk about Build Types and Flavors, for what are they used, what is the difference between them and what they have in common.

I needed an expandable list that would let us move item from a group to another. So I wrote this simple tutorial. It’s nothing difficult to achieve on your own, but I wanted to add this code here in case someone will need it. So, we will create an ExpandableList with items that can be moved
