Typically, each manager is backed by a corresponding system service; for example, the BluetoothManager is a facade for the BluetoothManagerService. Applications On the highest level of the stack are applications (or apps), which are the programs that users directly interact with. While all apps have the same structure and are built on top of the Android framework, we distinguish between system apps and user-installed apps. System Apps System apps are included in the OS image, which is read-only on production devices (typically mounted as /system), and cannot be uninstalled or changed by users.
