Optimizing Apps for Speed and UsabilityStart Free Course
If you’ve ever hit performance issues that affect your app’s usability, this course will teach you how to identify and diagnose your performance problems. By the end of this course, you’ll be able to perform exploratory tests, run profiling tools, use outputs to navigate to problematic code, and design a plan of attack to mitigate poor performance. You’ll also gain a higher level of understanding about how program code and the Android platform interact, which will help you optimize for performance in the future.
This free course is your first step towards a new career with the Android Developer Nanodegree Program.
Enhance your skill set and boost your hirability through innovative, independent learning.
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.

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.
