Set custom DNS servers on Android (requires root!).
Also works for mobile connection (3G, 4G, ...), only tested on KitKat (CyanogenMod 11).
The app currently use the setprop method. It might not work for you depending on your device/Android version.
I am aware of the four ndc resolver ... commands that seems to work for some people,
but setprop was working for me so I didn't bother with those ones. Please tell
me if you need it.
Warning: this is currently alpha software, use at your own risk!
Please verify yourself that the app is working for you (using tcpdump, etc.).
That is not because the net.dns[0-1] properties are successfully set that
Android will really use them as DNS servers! It really depends on the Android
version.
