Hello, I need to create an application where I control the installation flow myself. For example I would like to have fully automatic upgrades, without notifying the user, or uninstall apps that I don't allow on the system. I also need to see all applications installed on the system. The application is meant to be used in a fully controlled environment. Does anyone know how to do that? Or where I can find some documentation on how I install an apk on low level.
