For those who can get it to work there is the ip indicator on google play. Its what I use on the wolf launcher. If it doesnt work its usually because you need to do a little adb magic…I believe Troy has a video or tut on it. Some boxes it works without much, others are more locked down. Works great on my shield and mecool boxes.
When you try and install if it tells you you need permissions or adb you follow the onscreen directions. It will require a pc to help with setup at that point. Make sure you go into settings and allow ip widget all access as well as wolf launcher. In the mean time I will do a quick search and see if I can find instructions.
