Android pm命令用法

Sam综观有关PackageManager时，无意中发现Android 下提供一个pm命令，通常放在/system/bin/下。

这个命令与Package有关。且很有用。所以研究之。


0. Usage：

usage: pm [list|path|install|uninstall]

       pm list packages [-f]

       pm list permission-groups

       pm list permissions [-g] [-f] [-d] [-u] [GROUP]

       pm list instrumentation [-f] [TARGET-PACKAGE]

       pm list features

       pm path PACKAGE

       pm install [-l] [-r] [-t] [-i INSTALLER_PACKAGE_NAME] [-s] [-f] PATH

       pm uninstall [-k] PACKAGE

       pm enable PACKAGE_OR_COMPONENT

       pm disable PACKAGE_OR_COMPONENT

       pm setInstallLocation [0/auto] [1/internal] [2/external]

The list packages command prints all packages.  Options:

  -f: see their associated file.

The list permission-groups command prints all known

permission groups.

The list permissions command 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.

The list instrumentation command prints all instrumentations,

or only those that target a specified package.  Options:

  -f: see their associated file.

The list features command prints all features of the system.

The path command prints the path to the .apk of a package.

The install command installs a package to the system.  Options:

  -l: install the package with FORWARD_LOCK.

  -r: reinstall an exisiting app, keeping its data.

  -t: allow test .apks to be installed.

  -i: specify the installer package name.

  -s: install package on sdcard.

  -f: install package on internal flash.

The uninstall command removes a package from the system. Options:

  -k: keep the data and cache directories around.

after the package removal.

The enable and disable commands change the enabled state of

a given package or component (written as "package/class").

The getInstallLocation command gets 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

The setInstallLocation command changes the default install location

  0 [auto]: Let system decide the best location

  1 [internal]: Install on internal device storage

  2 [external]: Install on external media

1. 详细用法：
1.1：察看已安装的包：
pm list package
此时则显示全部已经安装的包名。

pm list package -f
也显示associated文件所在文件夹(即保存的APK文件)

1.2：察看已知的权限组：
pm list permission-groups

1.3：察看全部已知的权限：
pm list permissions

1.4：列出全部硬件相关信息：
pm list features

结果通常类似：

feature:reqGlEsVersion=0x20000

feature:android.hardware.bluetooth

feature:android.hardware.camera

feature:android.hardware.location

feature:android.hardware.location.network

feature:android.hardware.microphone

feature:android.hardware.sensor.accelerometer

feature:android.hardware.sensor.compass

feature:android.hardware.touchscreen

feature:android.hardware.wifi

1.5：列出指定包名的  associated 文件 (APK存档文件) 所在：
比如：
pm path com.TDiJoy.fane
package:/mnt/asec/com.TDiJoy.fane-1/pkg.apk


1.6: 安装APK：
pm install [-l] [-r] [-t] [-i INSTALLER_PACKAGE_NAME] [-s] [-f] PATH

PATH 指 APK文件绝对路径和文件名称。

比如：
pm install /data/3dijoy_fane.apk

这几个參数非常实用：
-r: 安装一个已经安装的APK。保持其数据不变。

-i：指定安装的包名。(没试出来)
-s: 安装到SDCard上。
-f: 安装到内部Flash上。

1.6：卸载APK：
pm uninstall 包名。
比如：
pm uninstall com.TDiJoy.fane


1.7: 得到和设置缺省安装位置：

The getInstallLocation command gets 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

The setInstallLocation command changes the default install location

  0 [auto]: Let system decide the best location

  1 [internal]: Install on internal device storage

  2 [external]: Install on external media

pm getInstallLocation
得到缺省的安装位置。

设置：
pm setInstallLocation <0|1|2>

0: 自己主动。

1：内部Flash。

2：扩展存储设备。






实例：怎样在海信2.2 STB上将APK安装到U盘中：
Sam首先尝试使用：
pm setInstallLocation 2
之后安装之，没实用。

后来做例如以下尝试：

   在其他设置->存储设备->制定默认存储设备中选择U盘为默认存储设备。

    # pm install   -s xxxx.apk

就能够成功。
