We started to work on special-purpose android project
Question 1: Please assume that we have our android rom, we deliver devices with this rom so we have app which names as "ApplicationManager" on this rom as bundled/pre-installed application and also ApplicationManager have all permissions
is it possible that this ApplicationManager app can install other application without installation confirm or uninstall any our installed applications? (our application are signed with same certificate, so developer is seen same)
Question 2: Is is possible when ApplicationManager is not pre-installed [we could not succeed this scenario]
Question 3: What is known source for Android and how can we be a known source on Android?
Thanks.
