Prerequisites and Requirements
To get the most from this course, you should have experience developing apps in Java on Android devices, understand the basics of the Android life cycle, and know how to perform basic operations in a terminal.
You also need access to an Android device, and working knowledge of Github, in order to follow along with the exercises.
If you’ve never developed a working Android app, check out our Developing Android Apps course before taking this one.
If you're unfamiliar with Github, check out our course on How to Use Git and Github.

Why Take This Course
Users want apps that download and run fast and efficiently. If your app performs well on low-end devices and slower internet connections, your user base, and thus your impact and potential for monetization, can increase dramatically. The ability to make conscious coding decisions that focus on the user experience is a trait that separates mediocre Android programmers from the leaders of the industry.
You may have the most exciting Android app in the world, but if it is slow and drains the battery, users will uninstall it, and leave you bad ratings because of it. Performance matters to users, so it must matter to you.
By the end of this course, you will understand how common performance problems arise from your hardware, OS, and application code. Using profiling tools to gather data, you will be able to identify and fix performance bottlenecks, so users can have that smooth 60 FPS experience that will keep them coming back for more.
