这里有新鲜出炉的精品教程，程序狗速度看过来！

Android移动端操作系统

Android是一种基于Linux的自由及开放源代码的操作系统，主要使用于移动设备，如智能手机和平板电脑，由Google公司和开放手机联盟领导及开发。尚未有统一中文名称，中国大陆地区较多人使用“安卓”或“安致”。

本篇文章是对Android 静默方式实现批量安装卸载应用程序进行了详细的分析介绍，需要的朋友参考下
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）

3、别忘记添加权限

    <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
