0. I use the night god emulator, other emulators also the same
adb server version (36) doesn't match this client(41); killing...
* daemon started successfully
List of devices attached

The solution is as follows.
1. Check the adb version

adb version

2. Enter the nocturnal simulator directory to view the version

nox_adb version

3. It is found that the two versions are inconsistent

You need to go to the platform Tools Directory of SDK and copy adb.exe

Rename adb.exe copied from the previous step to NOx_Adb.exe to replace NOx under nocturnal simulator_adb.exe

4. Restart the night God simulator

adb devices
