Android开发-使用pm命令进行package的管理，包括apk的安装和卸载（pm install && pm uninstall）
pm命令简介：
pm全称是package manager，是一个可执行程序。顾名思义，pm命令用来进行package的管理，例如安装apk，卸载apk，列出所有的应用的包名，列出权限等。
pm在Android系统中的源码位置：
frameworks\base\cmds\am\src\com\android\commands\pm
pm help:
在adb shell命令行，输入pm或者pm help，可以列出pm的使用帮助信息，部分信息如下：

pm list packages: prints all packages, optionally only
those whose package name contains the text in FILTER. Options:
-f: see their associated file.
-d: filter to only show disbled packages.
-e: filter to only show enabled packages.
-s: filter to only show system packages.
-3: filter to only show third party packages.
-i: see the installer for the packages.
-u: also include uninstalled packages.
pm list permission-groups: prints all known permission groups.
pm list permissions: prints all known permissions, optionally only
those in GROUP. Options:
-g: organize by group.
-f: print all information.
-s: short summary.
-d: only list dangerous permissions.
-u: list only the permissions users will see.
pm list instrumentation: use to list all test packages; optionally
supply to list the test packages for a particular
application. Options:
-f: list the .apk file for the test package.
pm list features: prints all features of the system.
pm list users: prints all users on the system.
pm path: print the path to the .apk of the given PACKAGE.
pm dump: print system state associated with the given PACKAGE.
pm install: install a single legacy package
pm install-create: create an install session
-l: forward lock application
-r: replace existing application
-t: allow test packages
-i: specify the installer package name
-s: install application on sdcard
-f: install application on internal flash
-d: allow version code downgrade
-p: partial application install
-g: grant all runtime permissions
-S: size in bytes of entire session
pm install-write: write a package into existing session; path may
be '-' to read from stdin
-S: size in bytes of package, required for stdin
pm install-commit: perform install of fully staged session
pm install-abandon: abandon session
pm set-installer: set installer package name
pm uninstall: removes a package from the system. Options:
-k: keep the data and cache directories around after package removal.
pm clear: deletes all data associated with a package.
pm enable, disable, disable-user, disable-until-used: these commands
change the enabled state of a given package or component (written
as "package/class").
pm grant, revoke: these commands either grant or revoke permissions
to apps. The permissions must be declared as used in the app's
manifest, be runtime permissions (protection level dangerous),
and the app targeting SDK greater than Lollipop MR1.
pm reset-permissions: revert all runtime permissions to their default state.
pm get-install-location: returns the current install location.
0 [auto]: Let system decide the best location
1 [internal]: Install on internal device storage
2 [external]: Install on external media
pm set-install-location: changes the default install location.
NOTE: this is only intended for debugging; using this can cause
applications to break and other undersireable behavior.
0 [auto]: Let system decide the best location
1 [internal]: Install on internal device storage
2 [external]: Install on external media
pm trim-caches: trim cache files to reach the given free space.
pm create-user: create a new user with the given USER_NAME,
printing the new user identifier of the user.

例如：
adb shell pm list instrumentationadb shell pm list instrumentation TARGET_PACKAGEpm命令常用参数：
（2）安装：

通过指定路径安装apk到手机中(与adb install不同的是adb install安装的.apk是在你的电脑上，而pm install安装的apk是存储在你的手机中)
参数
说明
-l 锁定应用程序 -r 重新安装应用，且保留应用数据 -t 允许测试apk被安装 -i 指定安装包的包名 -s 安装到sd卡 -f 安装到系统内置存储中（默认安装位置） -d 允许降级安装（同一应用低级换高级） -g 授予应用程序清单中列出的所有权限（只有6.0系统可用）
(3) 卸载：
pm uninstall [options]
#卸载应用
参数
说明
-k 卸载应用且保留数据与缓存（如果不加-k则全部删除）
（4）其它命令：
1. pm dump PACKAGE 打印给定的包的系统状态
2. list feature 打印系统的所有功能
列出所有硬件相关信息
3. list libraries 打印当前设备所支持的所有库4. pm clear 清除应用数据
