There exists a lot of contrariety on the web when it comes to the description of an Android System application. I will therefore explain the correct methodology here, which will hopefully enlighten you on whether you should place your Android application as a System application or not.
A System application is NOT an application which is signed by the OS’s platform signatures. This is a common mistake believed by many and we shall come to this later on. A System application is merely an application which is placed under /system/app folder in an Android device. An application can only be installed in that folder if we have access to the OS’s ROM (system.img). The application is placed under /app folder after the ROM has been extracted. A device which loads the custom ROM will have the new System application added. The benefit of a System application is that the application cannot be removed from the device (cannot be uninstalled by the user). This is only because /system/app is a read-only folder.
What Is "Rooting" Android?
On a basic level, rooting an Android phone means giving yourself superuser access.
What does that mean? If you use a desktop computer that allows multiple user accounts, some of those user accounts have more power than others, right? Administrative accounts allow you to do more, and they're also a little more dangerous - because they allow you to do more. A superuser account on Android is sort of like that administrator account. It allows more access to the operating system. That means more power, but it also means more potential for damage.
