Error while Installing APK

The problem is that the ADB has been killed. Just restart it

There are three ways:

1、 You can find Plattform tools in the SDK file, and you can find ADB, in this folder

double click the ADB to restart

2. You can also perform two-step command operations in CMD: 2

1、adb kill-server

2、adb start-server

3、 Restart the computer
