输入“adb logcat”命令出现“waiting for device” 信息被挂起

Question

当我在终端输入adb devices命令时，显示设备已连接

List of devices attached
0123456789ABCDEF device

但是当我输入adb logcat命令，系统显示以下信息，被挂起

waiting for device

这是什么原因呢？我是在 cts上测试的。

你可以试试下面的步骤，但是不能保证能否帮的上你:

# Kill and restart      
$ adb kill-server      
$ adb start-server     
 daemon not running. starting it now *      
 daemon started successfully *         

# Device appears, but is listed as offline

$ adb devices      
$ adb logcat
