Preface
The problem encountered with the emulator that comes with IntelliJ IDEA has never been solved. This error has been reported for a few days, and I have tried various methods of Google + Baidu (I always feel that the details are not solved). Originally wanted to hold on for a long time (but to solve the urgent need), I had to give up the simulator and go directly to the real machine to test!
adb devices
List of devices attached
emulator-5554 device
Real machine test steps
Create a New Project ——> select Empty Activity ——> Click Next to
see the prompt selection.
First let the phone enter the developer mode
To enter the developer mode, click below:

Note: Remember to turn on USB debugging
As shown in the figure: This has been connected to my phone (the phone model appears)
Open cmd, enter the code, as shown in the figure below, you can also test whether the phone can be connected
adb devices

When I clicked to run in IDEA, (that is, the button in the picture below), the 
phone responded accordingly.
This is how the first app is
completely downloaded.
Actual mobile test
If it’s an app written by myself, it’s better. Just run it and you can test it. I’ll update it later (I haven’t started learning yet). I owe it first (If I didn’t update it, please comment on Liu Ya)
Temporarily use other people's apk hahahaha. Go to the pea pod on the computer (you can download the apk on this website) to search for a simple app and download it.
For example, if I download a baby's riddle, I
don’t need to choose this
Open cdm, install
>adb install 路径/名称.apk
E.g
adb install F:\INSTALL/110_89c01f23201e1bc7566d77594a3f104c.apk
Note: If the above does not work, use the following two methods
Send the apk file directly to the phone for download and installation
Or you can download and install it directly in the mobile software store
After downloading, you can directly test the function and perform the black box test .
