推荐答案
的 INSTALL_PACKAGES 许可被标记为系统/签名作为你的可以看到这里。这意味着，除非你是一个系统的应用程序或已经使用相同的证书持有的许可，在这种情况下是系统应用程序签名。与OEM使用签名的Android分布的关键签字是不是一件很容易在我所知道的任何情况下获得的。
The INSTALL_PACKAGES permission is marked as system/signature as you can see here. This means unless you are a system app or have been signed with the same certificate as the app that holds the permission, which in this case is the system. Being signed with the key the OEM uses to sign the distribution of Android is not something that is easily obtained in any case I know of.
编辑：有多个的的运行到哪里他们的系统正常应用程式不再工作在4.4的情况下，因为把你的应用程序中的 /系统/应用程序不再自动助学金制度的人的实例-level权限。你必须把你的应用程序中的 /系统/私法应用为被授予适当的权限。
There are multiple instances of people running into instances where their system apps no longer function properly in 4.4, because putting your app in /system/app no longer automatically grants system-level permissions. You have to place your app in/system/priv-app for the proper permissions to be granted.
