这个修改是客制化的需求 没啥可说 需要的可以参考思路。
这个 修改主要在 Android 系统中添加了两个开关，一个用于控制 APK 的安装，另一个用于控制 APK 的下载。
修改的文件:
frameworks/base/services/core/java/com/android/server/pm/PackageManagerService.javapackages/providers/DownloadProvider/src/com/android/providers/downloads/DownloadProvider.java
文件修改说明:
PackageManagerService.java: 在createDataDirsLI方法中，添加了一个开关APK_install_finish_switch。当此开关为 true 时，如果系统 APK 安装完成 (APK_install_finish为 true)，则禁止安装任何 APK。DownloadProvider.java: 在insert方法中，添加了一个开关DISABLE_DOWNLOAD_SWITCH。当此开关为 true 时，禁止下载任何 APK 文件。
