My mobile phone is Mi 9 CC, and I found a lot of bloggers' articles, but they didn't talk about the problem of "Run "app"" not being displayed.
solution
- Install the Android studio configuration environment
- Open Android studio -- File -- Settings... , select Android SDK, select the version number for debugging on your mobile phone to download, then switch to SDK Tools, and download Google USB Driver
- Open Device Manager, find your phone, browse your computer for 㐑program software, and find the file location where Google USB Driver is installed. Click Next to install the driver.
- At this time, if the Run "app" is not displayed in Android studio, go back to the device manager, find the right button of the phone, disable it, and then enable it. Finally, go back to Android studio and you will see Run "app".
- Another problem is that clicking Run "app" prompts an error message, as shown in the figure
- Click on the app and select Edit Configurations.. Change Launch to Nothing, then Apply, and click ok to get it done.

Summarize
The Run "app" has not been displayed. It may be because the program has not been refreshed after installation. This is just my guess. Well, I can finally check the project problem with peace of mind.
