官网下载地址:http://adbdownload.com/
根据自己的操作系统选择下载对应的安装包,本文以Windows为例
将设备(如手机/平板)的USB调试打开, 不同设备和不同版本的开启方式不同,根据实际情况处理.
USB调试打开之后, 将设备(如手机/平板)等通过数据线连接到电脑上, 然后打开cmd工具,执行以下命令
PS D:\Software\AndroidKiller_v1.3.1\bin\adb> .\adb.exe devices
List of devices attached
稍等几秒钟, 安卓设备将弹出提示:"是否允许USB调试", 点击允许即可
再次执行devices
命令, 就可以从列表中看到设备了
PS D:\Software\AndroidKiller_v1.3.1\bin\adb> .\adb.exe devices
List of devices attached
88Y5T19A17001949 device
通过adb -s [device] logcat
命令, 可以看到设备的系统日志信息
PS D:\Software\AndroidKiller_v1.3.1\bin\adb> .\adb.exe -s 88Y5T19A17001949 logcat
--------- beginning of crash
05-27 20:48:46.431 434 434 F libc : Fatal signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 0x14 in tid 434 (init), pid 434 (init)

05-27 20:48:46.432 434 434 F libc : crash_dump helper failed to exec, or was killed
可以直接进入设备, 再执行logcat
命令.
PS D:\Software\AndroidKiller_v1.3.1\bin\adb> .\adb.exe -s 88Y5T19A17001949 shell
HWTAS:/ $ logcat | grep conn
logcat | grep conn

直接进入设备shell后再使用logcat
的好处是, windows不支持的常见linux命令, 在shell里面可以执行, 例如grep
