我有一个在inpeage os ver上运行的moto x4。 16我想禁用APK的安装，所以在线搜索后，我发现删除或禁用packageInstaller（通过debloater或adb pm命令）将禁用安装apk的选项，问题是，如果禁用packageInstaller似乎禁用手机无法启动（可能系统需要ParketInstaller），它会告诉我进行数据擦除和出厂设置，因此我的问题如下，可以禁用它不应允许安装新应用程序但不应允许安装新应用的问题但是仍然已启用，以便手机启动？，或者是否有另一种方式阻止新应用的安装？
提前感谢
i have a moto x4 running on lineage OS ver. 16 that i wanna disable installation of APK'S, so after searching online i found that deleting or disabling the packageinstaller (via debloater or adb pm commands) will disable the option of installing APK'S, the issue is that it seems that if the packageinstaller is disabled then the phone cannot boot (probably the system needs the packageinstaller) and it will tell me to make a data wipe and a factory reset, so my question is as follows is it possible to disable the packageinstaller that it should not allow installation of new apps but still be enabled so the phone can boot?, or is there another way of blocking the installation of new apps?
thanks in advance
这个问题提供了各种方法，因为您似乎依靠用户缺乏DevVy的未知程度。
a）最简单：如果您的用户不是Android技术，并且您没有安装在设备上的App Store，为什么假设他们知道APK是什么以及在哪里获取一个？
b）但是，如果您认为这太简单，则可以禁用未知源并隐藏用户的设置（这应该在Reg手机上工作，但不确定Lineage OS。） adb shell pm uninstall -k --user 0 com.android.settings.<settingName> 要禁用一个特定的设置，已知在某些设备上工作，您也可以在包管理器上尝试，因为它不会从手机中删除APK只是寄存器，但是恢复出厂设置将返回设置，并且您必须调查阻止用户执行工厂重置。
有许多方法可以提供类似的保护水平。
c）因此，（如果您认为一个非DEV用户将弄清楚，则似乎父母控制应用程序和/或应用程序管理员将是最完整的基本级别保护。
d）您可以通过操作系统获得超级深度并播放 - 可能重新编译包管理器应用程序。
总结：在一天结束时，Android需要PM才能正常运行。使用固件预加载的PackageInstaller应用程序只是在您的设备上安装APKS的许多方法之一，因为它只是用于卸除包安装程序应用程序时不会消失的原始Android功能的UI。以完全和不可逆转地禁用此功能，以一种非常经验的DEV不能规避是一个非常复杂的工作。然而，App Manager或父母控制解决方案通常可以从普通用户提供附近的完整安全性。
This question offers itself to a variety of approaches, because it seems that you are relying to an unknown extent on your user's lack of dev savvy.
A) Simplest: if your user is not an android tech, and you have no app store installed on the device, why assume that they know what an apk is and where to obtain one?
B) however, if you think that thats too simple , you can disable unknown sources and hide the setting from the user, (that should work on a reg phone, though not sure about lineage OS.) adb shell pm uninstall -k --user 0 com.android.settings.<settingName> to disable a particular setting has been known to work on some devices, you can try it on the package manager as well, as it does not remove the apk from the phone just de-registers, though a factory reset will return the setting, and you'd have to look into preventing the user from performing factory resets.
there are many approaches that would offer a similiar level of protection.
C) Therefore, (if you think a non-dev user will figure that out,) it seems that parental control apps and/or app managers would be the most complete basic level protection.
D) you can get super deep and play around with the OS - possibly recompile the package manager app.
in summary: at the end of the day android requires pm in order to function properly. the packageinstaller app that comes preloaded with your firmware is only one of the many ways to install apks on your device because it is only a UI for a native android functionality which doesnt disappear when the package installer app is removed. to fully and irreversably disable this functionality in a way that only very experienced dev cannot circumvent is a very complicated job. However an app manager or parental control solution can usually offer near complete security from an average user.
