Errors using geolocation

Galaxy Watch for Tizen Tizen Web APIs
1

Hello, I’m a developer working on some fitness apps for the Samsung watches, and I’ve hit a roadblock with using the geolocation API. I’ve copied the source code from the Tizen docs on geolocation, and it’s still giving me errors. I’m testing on a Gear S3 Frontier and my location setting is on.

This is the code:

class GPS {
    constructor() {
        this.currentPosition = { latitude: 0, longitude: 0, distanceToStart: 0 };
        this.startPosition = { found: false, latitude: 0, longitude: 0 };
        this.tracker = 0;
        this.startTracking();
    }
    found(lat, lon) {
        if (!this.startPosition.found) {
            this.startPosition.latitude = lat;
            this.startPosition.longitude = lon;
        }
        this.currentPosition.latitude = lat;
        this.currentPosition.longitude = lon;
        this.currentPosition.distanceToStart = calcDistance(this.startPosition, this.currentPosition);
    }
    startTracking() {
        if (navigator.geolocation) {
            let settings = {enableHighAccuracy: true, timeout: 10000, maximumAge: 1000000};
            navigator.geolocation.getCurrentPosition(location_success, location_fail, settings);
            // this.tracker = navigator.geolocation.watchPosition(location_success, location_fail, settings);
        } else {
            output.innerHTML = ‘Geolocation is not supported.’;
        }
    }
    stopTracking() {
        if (navigator.geolocation) {
            navigator.geolocation.clearWatch(this.tracker);
        } else {
            output.innerHTML = ‘Geolocation is not supported.’;
        }
    }
}

function location_success(position) {
    gps.found(position.coords.latitude, position.coords.longitude);
    output.innerHTML = "Position found: ", gps.currentPosition;
}

function location_fail(error) {
    switch (error.code) {
        case error.PERMISSION_DENIED:
            output.innerHTML = ‘User denied the request for Geolocation.’;
            break;
        case error.POSITION_UNAVAILABLE:
            output.innerHTML = ‘Location information is unavailable.’;
            break;
        case error.TIMEOUT:
            output.innerHTML = ‘The request to get user location timed out.’;
            break;
        case error.UNKNOWN_ERROR:
            output.innerHTML = ‘An unknown error occurred.’;
            break;
    }
    gps.startTracking();
}

I keep getting the error “location information is unavailable.” If anyone has successfully figured out how to implement this into a web app, please let me know. Any help will be appreciated. Thanks!

This error is often thrown when missing location privilege or GPS is not enabled (watch settings/connectivities/location).

You need to enable GPS on the watch and on the connected phone also. Your phone must be connected with GEAR app to your watch to share location. Also try not to use high accuracy and increase timeout to 30 seconds.
