Adjust VS permissions

Question

First of all, I am not involved in the development of any Android application. I am curious.

The question arises: does the application need to get root privileges in order to declare its necessary permissions in the manifest?

I mean, if my application does not state that it needs to get camera input, can it call some APIs or executable files and acquire the camera after it becomes root?

I know this may sound silly, but I repeat, I'm just curious to know about the Android features.

Answer 1

On your regular Android root device (which will use the Superuser application and its corresponding su binary) applications that request root access can only execute commands with root privileges through the su binary code.

So, yes , since the application itself still works as an undirected user process, so all it needs to do using the “normal” APIs is still need the correct permissions. Therefore, if you want (as in your example) to access the camera using the regular Java API, you will not be able to do this if you did not declare this permission.

But no , if the application requests and receives root privileges through the su binary, you can do anything inside this command. Therefore, if you wrote a special binary or script that can access the camera outside the usual API methods, this might work. (I suspect this will be more trouble than it's worth).
