I made an app for android wear watches to control the HERO4 cameras. It's not a traditional android wear app that you can access from your wear launcher or from Start
It creates two notifications, that you swipe left to reveal controls (like the gmail app has to reply email) one of the notifications changes the mode and the other starts/stop recording or hi light tag a moment.
Tested on a lg g watch, nexus 6 (phone needs to be on and connected to the GoPro via WiFi and smartwatch via bt) and a GoPro HERO4 Black.
Why I didn't make a traditional app?
I made the app, when skiing with it but discovered that it was a pain everytime I wanted to take a picture or record a new video I had to open the app, wait until it reconnects and because the watch sleeps the app closed. A notification with controls is way better, just wake your watch, swipe down, swipe left. No "waiting for connection" or "connection lost"
The app needs to be simple and easy to control. I tried to add the basic commands to the app. No more commands other wise the app will be a mess.
Download the app, connect your GoPro via WiFi to your phone and check that you can see the live preview using the official GoPro app, then open the weargopro app, swipe right the notification to keep it and check your watch for the two notifications. Swipe left to reveal controls.
