Android P实现静默安装的方法示例(官方Demo)

2023-07-31 13:42:06 73

Android9.0无法通过以下两种方式实现静默安装：

1.runtime执行shellcmd
2.PackageInstall反射机制

但是Google已经给我们推荐了相关的APIDemos，所以建议大家多看看源码~

在frameworks/base/core/java/android/content/pm/PackageInstaller.java有段关于该类的介绍：

翻阅源码，InstallApk*.java相关的一共两个demo
InstallApkSessionApi.java//静默安装
InstallApk.java//普通安装，调用系统installintent进行安装

下面是InstallApkSessionApi.java的具体demo

packagecom.example.android.apis.content;

另外，权限要求：

需要系统签名
permission
