Android pm命令詳解

在看相關PackageManager代碼時，無意中發現Android 下提供一個pm命令，通常放在/system/bin/下。這個命令與Package有關，且非常實用。所以研究之。

The setInstallLocation command changes the default install location
0 [auto]: Let system decide the best location

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
此時則顯示所有已經安裝的包名。

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：察看所有已知的權限：
pm list permissions

1.4：列出所有硬件相關信息：
pm list features

結果通常類似：
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

這幾個參數很有用：
-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。

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

1.8: 得到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
得到缺省的安裝位置。

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首先嘗試使用：
pm setInstallLocation 2
之後安裝之，沒有用。

後來做如下嘗試：
*在其它設置->存儲設備->制定默認存儲設備中選擇U盤為默認存儲設備。
# pm install -s xxxx.apk*

就可以成功。
