Provide quick feedback: If you've opted into sharing usage statistics to help improve Android Studio, you'll see two new icons in the status bar at the bottom of the IDE window--a smiling face and a frowning face. Simply click the icon that best represents your current experience with the IDE. When you do so, the IDE sends usage statistics that allow the Android Studio team to better understand your sentiment. In some cases, such as when you indicate a negative experience with the IDE, you'll have an opportunity to provide additional feedback.
If you haven't already done so, you can enable sharing usage statistics by opening the Settings dialog (Preferences on a Mac), navigating to Appearance & Behavior > System Settings > Data Sharing, and checking Send usage statistics to Google.
