Source code of a specific Device

[Ruhi Sharma]

Hello,

I have made small changes in the source code of the Android and now it is working fine with the emulator. I also developed a app which requires read log permission. Since I was working with the emulator, I provided the permission using the shell of the emulator.

Suppose I am a developer in a Android device company. Since each device customize the source code. So can I assume that the changes which I did in the emulator, I can also do to the device by customize the Android source initially. If I want the app to initially present in the device, for this do I need to make this app a system app? Can we provide any permission to the system app?

Thanks in Advance

Yes to both questions. If you want the app to be installed by default in your ROM then you should make it a system app and provide it with appropriate permissions. 

look at selinux for permissions definition.
