Reason:The adb version of the Night God emulator is inconsistent with the adb version of the Android sdk
Solution:
1. Find the android sdk
（1）File--->Project Structure
(2)SDK Location: note the location of the sdk
2. Find the adb file in the sdk
SDK-->platform-tools-->adb.exe
3. Copy adb.exe in the sdk to the bin of the Yeshen simulator, and replace abd.exe in the bin.
The problem is solved! !
If the original Locat has a problemNo connected devices, it is also the reason. After replacement, Locat can be used normally
