Learning Android Application Development
By :

So far you have seen how to create dynamic lists with a static data source (a Java array in our previous examples). In this chapter, you will learn how to request and retrieve data from Internet origins. There is a huge market for hyperconnected and hypersocial applications, so we can imagine how critical it is to rely on a good implementation of the networking part of the application. If it is done wrong, it might cause serious performance issues, never-ending activity indicators, or even application crashes.
We will initially focus on how to request permissions and on background tasks and later move on to how networking works internally and how to add widely used third-party libraries to simplify all the connection needs our application might have.
