Android下pm 命令詳解 - 安裝APK

Sam在看相關PackageManager代碼時，無心中發現Android 下提供一個pm命令，一般放在/system/bin/下。這個命令與Package有關，且很是實用。因此研究之。


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. 具體使用方法：
1.1：察看已安裝的包：
pm list package
此時則顯示全部已經安裝的包名。

pm list package -f
也顯示associated文件所在目錄(即保存的APK文件)

1.2：察看已知的權限組：
pm list permission-groups

1.3：察看全部已知的權限：
pm list permissions

1.4：列出全部硬件相關信息：
pm list features

結果一般相似：

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存檔文件) 所在：
例如：
pm path com.TDiJoy.fane
package:/mnt/asec/com.TDiJoy.fane-1/pkg.apk


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

PATH 指 APK文件絕對路徑和文件名。

例如：
pm install /data/3dijoy_fane.apk

這幾個參數頗有用：
-r: 安裝一個已經安裝的APK，保持其數據不變。
-i：指定安裝的包名。(沒試出來)
-s: 安裝到SDCard上。
-f: 安裝到內部Flash上。



1.6：卸載APK：
pm uninstall 包名。
例如：
pm uninstall com.TDiJoy.fane


1.7: 獲得和設置缺省安裝位置：

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
獲得缺省的安裝位置。

設置：
pm setInstallLocation <0|1|2>

0: 自動。
1：內部Flash。
2：擴展存儲設備。






實例：如何在海信2.2 STB上將APK安裝到U盤中：
Sam首先嚐試使用：
pm setInstallLocation 2
以後安裝之，沒有用。

後來作以下嘗試：

   在其它設置->存儲設備->制定默認存儲設備中選擇U盤爲默認存儲設備。

    # pm install   -s xxxx.apk

就能夠成功。
