Sam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
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

- -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.

- 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
複製代碼
1.具體使用方法:
1.1:察看已安裝的包:
pm list package
顯示所有已經安裝的包名。pm
pm list package -f
也顯示相關文件所在目錄(即保存的APK文件)
1.2:察看已包知的權限組:
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 相關 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指示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。
1.6:卸載APK:
pm uninstall 包名。
例如:
pm uninstall com.TDiJoy.fane
1.7: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
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- > 儲存設備- > 制定默認存儲設備中選擇ü 盤為默認存儲設備。
#pm install -s xxxx.apk
就可以成功。
