Launch error: failed to connect to remote VM

Alas, there are a lot of problems today, but as long as you constantly modify and record them, I believe the gains are still very huge ^-^.

The problem above will not be explained. I read some solutions written by some people on the Internet, but I want to modify them. So I went to stackoverflow and found a simple and easy-to-use method. The original post was in English, however, the steps are very simple: Close eclipse --> unplug USB --> open the task manager and delete all eclipse.exeand adb.exe --> re-open eclipse --> re-connect to USB.

Okay, the problem is solved, and no other settings are needed. This is just a small method. If you encounter the same problem but cannot solve it using this method, you should honestly check the settings of those tutorials on the Internet.
