Type of network interface (mobile or wifi)

[JurasicSTR]

Hi all!

Is there a way to detect type (cellular or wifi) of network interface on C, without using of jni.

In java it could be done by using "ConnectivityManager".

In android I found that network interfaces could have different names on different devices. On some devices wifi has "wlan0", but on other "eth0", moreover, on chines devices it could have any name.

For cellular network interfaces name starts with "rmnet".

So detection of type based on network interface name is not a solution.

Thanks in advance!

No reason to be scared of JNI for something like this. (If you are scared of Java, perhaps you are developing apps for the wrong platform.)

I`m not scared, I just want to make clean solution! I think there is definitively exist way to do that on C and not to make complicated implementations!

No there isn't. Anything you would cook in C would be very device-dependent. The only stable APIs you can rely for this are provided by the framework implementation running inside the VM, so JNI is the way to go to get something that works everywhere.
