Checking for root about libsu HOT 6 CLOSED

Shell.isRootAvailable()

from libsu.

Understand though, that the only way to check for root is to try to get su access, it's not a proper runtime permission

from libsu.

I see a Shell.rootAccess(), is this what you're referring to? Also, just for clarification, does this check whether the device has root or whether the app has root privileges?

from libsu.

Shell.rootAccess() is the instance method, Shell.isRootAvailable() is static

from libsu.

@gurupras when you use Shell.rootAccess(), it will actually request a root shell (execute su), and cache the result in the container. Unfortunately, there is no way to know whether root is available until you actually request for it.
You can check the availability of the su command, but there is no way to know whether it actually works or not (e.g. user denies root access by default)

You can check the availability of the su command

As I understand it, the way to do this would be to open a new non-root shell and then run command -v su or similar? Would you consider adding a utility function to avoid this boilerplate? Something like boolean deviceIsLikelyRooted().

The main use case is communicating to users of non-rooted devices that certain functionality will not work, without throwing up an unnecessary permission request on rooted devices (it irritates me when apps do this; I don't want to grant permissions until they're needed for something). No fancy tricks — I am not looking to detect root functionality if the user wants to hide it from me :)
