Android 靜默方式實現批量安裝卸載應用程序的深入分析

前段時間做了一個批量安裝卸載應用程序的小應用，由於安裝卸載應用程序的部分API是隱藏的，所以必須在ubuntu下下載Android系統源碼，並編譯之後使用MM命令編譯生成APK文件，其實也難。

思路是這樣的，在XX/packages/apps目錄下有一個PackageInstaller的應用程序，Android機器中安裝卸載都是由這個應用程序完成的。但是它沒有批量安裝和卸載的功能，如果要在自己的應用程序中添加批量安裝和卸載的功能，其實很簡單，只需要參考PakcageInstaller裡面的安裝卸載代碼加個循環就可以了。但值得注意的是在編譯的過程中必須復制PackageInstaller裡面的Android.mk文件，修改文件為工程目錄名。
好了，廢話不再多說，下面是關鍵代碼
1、 Android.mk文件
復制代碼 代碼如下:
LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)

LOCAL_MODULE_TAGS := optional

LOCAL_SRC_FILES := $(call all-subdir-java-files)

LOCAL_PACKAGE_NAME := PackageInstaller
LOCAL_CERTIFICATE := platform

include $(BUILD_PACKAGE)

復制代碼 代碼如下:
    LOCAL_PATH:= $(call my-dir) 
    include $(CLEAR_VARS) 

    LOCAL_MODULE_TAGS := optional 

    LOCAL_SRC_FILES := $(call all-subdir-java-files) 

    LOCAL_PACKAGE_NAME := PackageInstaller 
    LOCAL_CERTIFICATE := platform 

    include $(BUILD_PACKAGE) 

2、PakcageInstaller.java文件（關鍵代碼）
復制代碼 代碼如下:

3、別忘記添加權限
復制代碼 代碼如下:
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
        <uses-permission android:name="android.permission.INSTALL_PACKAGES" />
        <uses-permission android:name="android.permission.DELETE_PACKAGES" />
        <uses-permission android:name="android.permission.CLEAR_APP_CACHE" />
        <uses-permission android:name="android.permission.READ_PHONE_STATE" />
        <uses-permission android:name="android.permission.CLEAR_APP_USER_DATA" /> 

復制代碼 代碼如下:
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/> 
        <uses-permission android:name="android.permission.INSTALL_PACKAGES" /> 
        <uses-permission android:name="android.permission.DELETE_PACKAGES" /> 
        <uses-permission android:name="android.permission.CLEAR_APP_CACHE" /> 
        <uses-permission android:name="android.permission.READ_PHONE_STATE" /> 
        <uses-permission android:name="android.permission.CLEAR_APP_USER_DATA" /> 

以上代碼在Android2.1的SDK中編譯通過，並正確批量安裝卸載應用程序
