Any users want an app that is easily downloadable and runs fast. The [course_title] course focuses on the factors that affect the Android Performance.

If your app runs well in on low-end devices and slower internet connections, it will reach to the users dramatically. Throughout the course, you will learn how to identify and diagnose your performance problems.

No matter how good your app is, if your app is slow and drains the battery, users will leave bad ratings and uninstall it immediately. The purpose of the course is to teach you the techniques of improving the performance of your app.
