In this app you would get familiar with some more advanced terms and features in android development its a small group of apps that are built within one big app and each of these apps contains some information on what we used to develop it and a link to check the source code to get more familiarized with the terms used.

Note: This app is not used to teach you programming but instead it helps you to see terms and code of simple apps. This is the advanced-kit there is a lower version you could search for them and there is a professional kit if you are already familiar with the high level stuff.

Hope you enjoy the app!
