本文介绍一种安卓卸载系统应用的方法，如果你和我一样喜欢瞎折腾，有那么一点强迫症，希望对你有用。作为一名安卓开发者，大学以前总喜欢刷不同刷机包（ROM）、爱装不同的Launcher桌面体验，不过工作了没以前爱折腾了。安卓提供的adb工具不用多介绍，网上都有很多教程。

一. 实验条件

• LG V30 （Android 9.0）
• 较新adb驱动
• 对应的USB调试线一根

二. 安装adb驱动

下载360手机助手，安装USB连接手机，360手机助手对手机adb驱动支持很好，直接连接就好了。确定adb驱动安装好后，任务管理器将360Mobile相关的进程干掉。重新连接adb，最后使用cmd或者AS自带的Terminal进入命令行，熟悉我们的adb命令就行了。

三. adb卸载预装应用步骤

1、查看adb版本

确认adb版本较新，我自己亲自试了在自己笔记本电脑adb工具执行命令用不了，总是提示如下打印：

F:\mypc>adb devices
adb server is out of date. killing…
daemon started successfully *
List of devices attached
810e909e offline

尝试了网上的方法，还是没有解决，但想到公司电脑好像没有问题的。于是对比了两台电脑adb的版本，还是存在差异，或许是adb安装路径有问题！

F:\mypc>adb version
Android Debug Bridge version 1.0.29

E:\other>adb version
Android Debug Bridge version 1.0.41
Version 29.0.1-5644136
Installed as C:\Windows\system32\adb.exe

2、查看系统中所有包

执行下面命令，将打印复制到记事本中，方便后面查找。

adb shell pm list packages

3、确认不知名的应用包名（较低安卓版本可直接查看应用包名）

有的应用我们可以通过包名就可以判断哪一个应用，但有的应用我们是确定不了的。那么就需要确认当前运行的应用的包名，记住安卓Activity和Application packagename是有关系的！好几种方法，一种不行尝试另外一种哦。
法一：

1、在手机上打开app
2、执行：adb shell dumpsys window w |findstr / |findstr name=

1、在手机上打开app
2、执行：adb shell dumpsys activity activities
3、分析打印

执行：adb shell dumpsys activity activities 后，我拿到的打印如下，具体分析我们就知道包名和应用名是哪一个了。这条命令会将activity堆栈信息和活动信息告诉我们。

1、手机打开应用
2、执行：adb shell dumpsys activity top
linux: adb shell dumpsys activity | grep “mFocusedActivity”
windows: adb shell dumpsys activity | findstr “mFocusedActivity”

这种方法和法二类似，但仔细看一下下面的打印太恐怖了。我打印了安卓Launcher桌面活动信息，居然什么都暴露了，我擦谷歌爸爸太强大了！

4、卸载你想卸载的应用

上一步中我们拿到了你想要的卸载应用的包名了，这一步就小儿科了！
提供下面命令：

卸载： adb shell pm uninstall --user 0 应用包名
停用： adb shell pm disable-user 应用包名
启用： adb shell pm enable 应用包名

参考：
【1】、adb命令查看当前运行activity
【2】、android 开发中Adb命令的使用查看所有的Apk包
