I am trying to implement mobile app Analytics through Mobile Services SDK by provided sample app , It has only worked for me once where I was able to see some hits in Blood hound post which nothing is working out and I am not able to see image request at all .
I have tried to put up a logger to see whats happening and this is what I am always seeing :
It looks like your device/emulator isn't able to communicate with your Bloodhound instance. I would double-check your ADBMobileConfig.json file to verify it's pointing at the IP Address of your Bloodhound proxy. Hope this helps.
