I notice the Garmin stock watch faces have access to altitude (perhaps latest stored?). I have tried to gain similar access by attempting to invoke various methods and changing permissions in the Manifest (I get "Permission required" errors). Is there a specific method that provides this last stored information?
No special permission needed, and be sure to null check it
Thank you, Jim! I see my error. I had previously created an app where I invoked Sensor,getInfo().altitude, which is what I tried for the watch face. It makes sense that sensor info would not be available for a watch face to preserve battery life (I'm assuming). Your comment worked. Thanks, again!
Activity.Info can be useful in watchfaces for other things too. For example, that's how you can get the lat/lon for things like sunrise/sunset calculations.
