I'm using Cloudpebble to develop a watchface for myself. Everything compiles well and I've not had troubles sending the face to my watch until now.
After compiling the watchface and linking to the phone, it returns an error of "Installation failed. Check your phone for details." However, the phone does not shed any light on what these details might be.
I've checked the usual suspects such as full watch slots and inability to connect to phone, but those were not issues in my case and I'm rather stumped as to what the problem might be. Any help would be greatly appreciated.
Pebble App Version:
2.1.0-beta9 2.1 (Android)
Watch Firmware: 2.7 2.8
Watchface Source: GitHub
UPDATE 11/20:
I didn't mention before that the phone app would crash often when attempting to load my watchface on the watch because I chalked it up to beta software. Today brought watch firmware 2.8 and phone app 2.1 proper, and while the phone app no longer crashes, the mysterious error continues without additional information on the phone.
The answer to my particular issue, as it turns out, was that I had unused fonts. It's not a very obvious problem, so I hope this helps others out.
The main issue really was poor error reporting from cloudpebble due to the lack of error clarification returned from the pebble app to cloudpebble.
I have opened an issue on the cloudpebble github (that's where I found the answer) so if any further developments happen, they'll more than likely be there.
