Watch face: how to get activities from the last seven days

ViceCaycedo 1 month ago

Hey all,

I'm trying to get activities from the last 7 days. Is there an efficient way to do this?

Right now, in the onUpdate method, I'm doing the following:

var userActivityIterator = UserProfile.getUserActivityHistory();

var nextActivity = userActivityIterator.next();

while (nextActivity != null) {

var startTime = nextActivity.startTime;

// check if start time is in last 7 days

nextActivity = userActivityIterator.next();

}

My concern is that this loops through all the user's activities, which seems like a lot of processing for an onUpdate function.

I have it all working, but I'm worried it will kill the battery life. Wondering if there is a better way to do this.

For context, I'm creating a watch face that will show the running mileage for your last 7 days (as opposed to this week like the complication offered by Garmin).

Appreciate any help! Thanks!

There is no better way to do it. Just do it less often if you are concerned about battery consumption,

I could do it less often (e.g. every hour) but it would be a bad user experience to see bad data for up to an hour.

Is there a way to trigger this when a new activity is completed?

The activity history iterator doesn't make any guarantees around the order of the activities so I can't keep a reference to the last event and check if there are any new events onUpdate without iterating through the entire history.

Do you have any suggestions?

When you start an activity or an app then your watchface is stopped. When you exit the activity, then the watchface is started. So you only need to run the code that checks for new activities when it starts IMHO.
