A "material design"-style activity indicator for Pebble.
pebble package install pebble-activity-indicator-layer
You must be using a new-style project; install the latest pebble tool and SDK
and run pebble convert-project on your app if you aren't.
Here is a basic example of how to use the ActivityIndicatorLayer in your app. For a more detailed example, check out the demo app.
static ActivityIndicatorLayer *s_activity_indicator_layer;
...
s_activity_indicator_layer = activity_indicator_layer_create(frame);
activity_indicator_layer_set_animating(s_activity_indicator_layer, true);
layer_add_child(window_layer, (Layer *)s_activity_indicator_layer);
