android如何静默方式来安装apk(3)

来源：互联网发布：ikbc mac 设置键位编辑：程序博客网时间：2024/04/29 18:17

通常情况下，android是没有提供静默方式的上层接口，我们需要在android源代码下来调用这个隐藏的接口来完成静默安装。
最重要的就是参考android系统目录下的packages/apps/PackageInstaller，
当中有两个文件 PackageInstallerActivity.java,InstallAppProgress.java ,前者就是我们通常看到的带有提示对话框的安装应用程序，后者是点确定安装后调用的intent。
现提供一个静默安装的关键类，该类在android2.2下成功编译, 其中通过循环调用接口instatllBatch则可实现批量安装
当然最后的应用程序别忘记添加权限
