(1) New sdk_home system variable, add the installation directory of the SDK;
(2) Add the directory of two folders tools and Platform-tools to the environment variable path:
";%sdk_home%\tools;%sdk_home%\platform-tools;"

Test environment variable is successful:
In the Windows Terminal Input command "adb shell", if prompted error:more than one device and emulator, enter the command "ADB devices" to see if there are multiple devices or virtual machines.
If multiple devices are found, you need to specify the serial number of the device for the ADB command, plus the parameter-S.
For example:
C:\USERS\ADMINISTRATOR>ADB Shell
Error:more than one device and emulator

C:\USERS\ADMINISTRATOR>ADB devices
List of devices attached
015D483BB053FA18_RNDISADB Device
emulator-5554 Device

C:\users\administrator>adb-s emulator-5554 Shell
