Android 静默方式实现批量安装卸载应用程序的深入分析

前段时间做了一个批量安装卸载应用程序的小应用，由于安装卸载应用程序的部分api是隐藏的，所以必须在ubuntu下下载android系统源码，并编译之后使用mm命令编译生成apk文件，其实也难。

思路是这样的，在xx/packages/apps目录下有一个packageinstaller的应用程序，android机器中安装卸载都是由这个应用程序完成的。但是它没有批量安装和卸载的功能，如果要在自己的应用程序中添加批量安装和卸载的功能，其实很简单，只需要参考pakcageinstaller里面的安装卸载代码加个循环就可以了。但值得注意的是在编译的过程中必须复制packageinstaller里面的android.mk文件，修改文件为工程目录名。
好了，废话不再多说，下面是关键代码
1、 android.mk文件

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)

    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（关键代码）

    <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" /> 

    <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" /> 

以上代码在android2.1的sdk中编译通过，并正确批量安装卸载应用程序
