android批量安装APK

    在android机上安装APK时一般都是借助PC端的91手机助手或者豌豆荚之类的工具；或者直接将APK下载到android机子上手动点击安装，手动安装时系统会弹出“是否要安装该应用程序？”的对话框让你选择是否安装，如果一次只安装一两个APK还可以在每次弹出对话框时选择“安装“，如果一次需要安装数十个时这是相当费力而且容易漏掉APK没有安装的。

    能不能自己写个应用来实现一次批量安装所有APK呢？答案是肯定的，但是对于一个只熟悉android应用开发的人员是办不到的。因为google为了防止出于一些特殊目的的开发人员编写应用程序偷偷的在你的android机子上安装一些有特殊目的的APK，已经将静默安装APK的API屏蔽了，在官方发布的SDK中是没有这样的API给你调用的。但是对于系统开发人员还是很容易开发出这样的应用的，因为我们可以在编译系统时去编译我们调用了google隐藏了的API的应用。

    先上个我写的批量安装APK应用的界面和批量安装APK时的效果图，该应用实现的功能是先扫描外置SD、TF卡下的所有APK，点击”安装APK“按钮后即开始一次批量安装完扫描到的APK，不需要用户去干预。

    该应用主要用到的是android.content.pm.PackageManager类下的installPackage方法来实现静默安装所有APK的。
