Library Feature1:

Description:

It fetches weather details based on the location of the user.

Code Snippet:

    fecthWeather: function () {
        let locData;
        geolocation.getLocation({
            success: function (data) {
                locData = data;
                console.log("The location fetched:" + JSON.stringify(data));
            },
            fail: function (data, code) {
                console.log('fail to get location. code:' + code + ', data:' + data);
            },
            complete: function () {
                console.log('in Complete');
            }
        })
        console.log('Location Data: ' + JSON.stringify(locData) + " lat: " + locData.latitude + " long: " + locData.longitude);

        this.lat = locData.latitude;
        this.long = locData.longitude;

        console.log("Lat : " + this.lat + " Long : " + this.long);

        let data;
        fetch.fetch({
            url: 'https://api.openweathermap.org/data/2.5/weather?lat=' + this.lat + '&lon=' + this.long + '&appid=9ca3abfc02f621a4fe7696f670f04a57',
            responseType: "JSON",
            method: 'GET',
            success: function (resp) {
                data = JSON.parse(resp.data);
                console.log("Data :" + data + " " + resp + " ");
            },
            fail: (data, code) => {
                console.log("fail data: " + JSON.stringify(data) + " fail code: " + code);
            },
            complete: () => {
                this.weather = data.weather[0].main;
                console.log("Weather :" + this.weather + " " + this.weather[0].main);
            }
        })
    }

Screenshot:

Note: Since latitude: 121.61934 and longitude: 31.257907 does not exists it throwing an error.

Flow chart description:

In fecthWeather function it will first fetches the locations details of the user i.e latitude and longitude, using openweather api fetches the weather details based on the latitude and longitude.

Library Feature2:

Description:

Fetches BPM, Calories burned and notification using an API created by me.

Code Snippet:

    fecthData: function () {
        let data;
        fetch.fetch({
            url: 'https://mocki.io/v1/cb0cd987-0c49-4e7c-9475-fb533723e2fd',
            responseType: "json",
            method: 'GET',

            success: function (res) {
                data = JSON.parse(res.data);
                console.log("Data :" + data + " " + JSON.stringify(res) + " ");
            },

            fail: (data, code) => {
                console.log("Fail Data: noti " + JSON.stringify(data) + " fail code: " + code);
            },
            complete: () => {
                this.bpm = data.bpm;
                this.kcal = data.cal;
                this.noti = data.noti;
                console.log(this.bpm + " " + this.kcal + " " + this.noti);
            }
        })
    }

Library Feature3:

Description:

Calculates number of steps walked.

Code Snippet:

function subscribePedometerSensor(context) {
    sensor.subscribeStepCounter({
        success: function (ret) {
            context.step = ret.steps.toString()
        },
        fail: function (data, code) {
            console.log('Subscription failed. Code: ' + code + '; Data: ' + data)
        }
    })
}

function verifyPermissions() {
    var context = ability_featureAbility.getContext()
    let permission = "ohos.permission.ACTIVITY_MOTION"
    var result = new Promise((resolve, reject) => {
        context.verifyPermission(permission)
            .then((data) => {
                resolve(true)
            }).catch((error) => {
            reject(false)
        })
    })
    return result
}

Advanced feature that could be implemented in Future in this library:

Calculating Blood Pressure and Calories Burned using respective API’s.

Conclusion:

smart watch four calculates Number of steps walked, BPM, Calories burned, fetches date and time and weather details based on location and notifications.
