Android 静默安装卸载

首先开头感谢这两篇文章，参考他们两个的改出来的（刚接触formwork）：

Android 7.1.1 Framework 修改记录(一) 静默安装/卸载 (pm命令抛异常的过来看看) - 知乎

 java - 使用 Runtime.getRuntime 在 Android 上运行 shell 命令 - IT工具网

改formwork成的两个文件：

路径：frameworks\base\services\core\java\com\android\server\pm

文件名：

PackageInstallerSession.java

PackageInstallerService.java

代码如下：
