I run Android Studio 1.5.1 under Ubuntu 14.04. I want to check the network usage of my application and hence tried the network monitoring tool from Android studio. However, for every emulator/emulated android I tried, I only get the message
Network monitoring is not available on your device
@AnyssaK was right. The Network Monitor doesn't work on emulators. Please read their comment.
Besides make sure that you selected the correct device in Android Monitor.
