本文实例讲述了android实现静默安装与卸载的方法。分享给大家供大家参考。具体如下：
方法1：【使用调用接口方法，由于安装卸载应用程序的部分API是隐藏的，所以必须下载Android系统源码，在源码下开发并编译之后使用MM命令编译生成APK文件】

安装、卸载相关权限：

<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" />

方法2：【需要获取root权限或者和rom拥有一样的签名，即让该apk以System的身份在系统中运行】

其他方法：一些第三方jar包等方式。
