Android Data Persistence

Course Summary

Being able to save or persist data within our apps is an important fundamental skill. It enables our users to save their work, remember their preferences, store all types of files for reuse, and more. These features are evident to some degree in almost every application. In this course, we will be learning about the different ways in which we can persist data in our apps. We will be creating an app which can make memes in order to learn about these different concepts. By the end, we will know what types of considerations come into play when developing an app with data persistence features.
