The following is the first few sections of a chapter from Exploring Android, plus headings for the remaining major sections, to give you an idea about the content of the chapter.


Changing Our Icon

Our ToDo project has some initial resources, such as our app’s display name and its launcher icon. However, the defaults are not what we want for the long term. So, in addition to adding new resources in future tutorials, we will change the launcher icon in this tutorial.

This is a continuation of the work we did in the previous tutorial. The book’s GitHub repository contains the results of the previous tutorial as well as the results of completing the work in this tutorial.

Read Me!

This tutorial assumes that you have learned the basics of working with drawable resources elsewhere. Ideally, that would be from the official documentation, but the documentation in this area is quite disorganized.

Another possibility would be learning it from The Busy Coder’s Guide to Android Development and its “Some Words About Resources” chapter and its “Icons” chapter.
