Android静默方式实现批量安装卸载应用程序

2012-05-09 19:28 796 查看
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

view plaincopyprint?

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)

3、别忘记添加权限

[html]
view plaincopyprint?

android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

<uses-permission
android:name="android.permission.INSTALL_PACKAGES"

<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
