关于安卓root过手机静默安装与卸载

    用到一个工具类AndroidCommon  详细了解地址：http://www.open-open.com/lib/view/open1385174381198.html   ,其中为我们提供了root后静默安装的工具类PackageUtils，其中包含安装与卸载。

   走下思路，首先静默安装要用到adb命令，所以手机必须root（至于360手机助手静默安装，无需root也可以静默安装，具体我也不清楚，哪位大牛清楚希望可以探讨下），在adb命令中执行pm install -r即可，具体可以参考AndroidCommon提供的类。工具类PackageUtil.sinstallSilent(context, path)静默安装与PackageUtil.uninstallSilent(this, path)静默卸载，都有返回值，返回值为1说明是成功的，具体返回值PackageUtil中有就不多说了 如果返回值不是1的话，可以执行普通的安装方法，接下来看代码

demo中只将AndroidCommon的工具类打包成Lib，可直接看源码
