| + | **Tip**: When testing on a virtual device, it is a good practice to start it up once, at the very beginning of your session. You should not close it until you are done testing your app, so that your app doesn't have to go through the device startup process again. To close the virtual device, click the **X** button at the top of the emulator, choose **Quit** from the menu, or press **Control-Q** in Windows or **Command-Q** in macOS. | ||
| + | |||
| + | ===Bonus=== | ||
| + | - Make the app display your name instead of the Hello World message | ||
| + | - Run the app on a physical device instead of the emulator | ||
