adb

一、adb是什么？

ADB（android debug brige） 用来操作（调试）android设备（比如android手机）的一套指令集

二、adb指令集

1.安装完成后查看adb

adb version

2.开启关闭server

adb start-sever
adb kill-server
一般使用
adb kill-server
adb devices会自动启动adb server

3.安装apk

普通安装 adb install <apk路径>
覆盖安装 adb -r install <apk路径>

4.卸载apk

adb uninstall <包名>
adb uninstall -k <包名> 保留配置文件的卸载

5.进入android内部执行linux命令

adb shell

6.退出android

exit

7.查看应用列表

adb shell pm list packages 显示所有应用
adb shell pm list packages -s 显示系统应用
adb shell pm list packages -3 显示第三方应用

8. 获取前台包名和activity名

adb shell dumpsys activity | grep mFocusedActivity
adb shell dumpsys activity | findstr mFocusedActivity

adb logcat|grep -i displayed
打开应用
或者：adb shell dumpsys activity | findstr -i run

就可以获取包名和activity名

9.启动应用

adb shell am start -n <包名><Activity名>

10.清除应用数据和缓存

adb shell pm clear <包名>

再次打开会要求重现选择权限等等操作

11.强制停止应用

adb shell am froce-stop<包名>

12.设备和电脑传输文件

从电脑上传文件到设备 adb push <电脑路径><设备路径>
从设备复制文件到电脑adb pull <设备路径><电脑路径>

已经push成功了

Administrator@MS-20161203XRNU MINGW64 /e
$ adb pull ./sdcard/Untitled-1.json .
./sdcard/Untitled-1.json: 1 file pulled, 0 skipped. 0.2 MB/s (9737 bytes in 0.042s)

pull成功了

13.设备截图

将模拟器当前显示截图 adb shell screencap <截图路径>
截图文件下载到电脑上adb pull <截图路径><电脑路径>

Administrator@MS-20161203XRNU MINGW64 /e
$ adb shell screencap ./sdcard/qiyeweixinjietu.png


查看android,已经保存在了sdcard中
Administrator@MS-20161203XRNU MINGW64 /e
$ adb shell
root@x86:/ # cd sdcard
cd sdcard
root@x86:/sdcard # ls
ls
$MuMu共享文件夹
qiyeweixinjietu.png

pull到电脑上查看

Administrator@MS-20161203XRNU MINGW64 /e
$ adb pull ./sdcard/qiyeweixinjietu.png .
./sdcard/qiyeweixinjietu.png: 1 file pulled, 0 skipped. 3.8 MB/s (101123 bytes in 0.025s)

adb logcat -c 清除旧日志
adb logcat -v time >./logact.log

Administrator@MS-20161203XRNU MINGW64 /e
$ adb logcat -v time > ./logcat.log
操作出现问题的步骤，会记录到logcat.log中

15.查看性能参数

查看系统资源 adb shell top| grep 包名
查看cpu信息 adb shell dumpsys cpuinfo
查看内存信息 adb shell dumpsys meminfo

Administrator@MS-20161203XRNU MINGW64 /e
$ adb shell top| grep  com.tencent.wework
