Fetch Google Fit Data Continuously

There are many health care applications in the market which are showing data related to physical activities like Steps, Distance, Calories, etc.

Yes, We can easily develop this kind of application using Google Fit APIs. Google Fit is providing sensor data like Steps, Distances and Calories.

There are many types of APIs available to get Fitness data. Like

• Sensor API
• Recording API
• History API
• Sessions API

Today we will discuss History APIs. Using this API you can get all the history data from that day when you had registered your account. And also you can get today’s data continuously.

First of all you need to add a library for Google fitness before using google fit apis in your project. Here I have mentions the gradle for fitness:

implementation 'com.google.android.gms:play-services-fitness:19.0.0'

implementation ‘com.google.android.gms:play-services-auth:18.1.0’

Also you need to add an auth library. Because before requesting data from google fit you need to identify the google user then using that user you can create a request for the google fit data.

Fetch History Data Till Now

private void requestForHistory(GoogleSignInAccount account) {
Calendar cal = Calendar.getInstance();
cal.setTime(new Date());
long endTime = cal.getTimeInMillis();
cal.set(2014, 9, 28);
cal.set(Calendar.HOUR_OF_DAY, 0); //so it get all day and not the current hour
cal.set(Calendar.MINUTE, 0); //so it get all day and not the current minute
cal.set(Calendar.SECOND, 0); //so it get all day and not the current second
long startTime = cal.getTimeInMillis();
DateFormat dateFormat = new SimpleDateFormat("dd MMM yyyy HH:mm:ss", Locale.getDefault());
Log.i(TAG, "Range Start: " + dateFormat.format(startTime));
Log.i(TAG, "Range End: " + dateFormat.format(endTime));
DataReadRequest readRequest = new DataReadRequest.Builder()
.aggregate(DataType.TYPE_STEP_COUNT_DELTA)
.bucketByTime(1, TimeUnit.DAYS)
.setTimeRange(startTime, endTime, TimeUnit.MILLISECONDS)
.build();
readHistoryData(readRequest, account);
}
private void readHistoryData(DataReadRequest readRequest, GoogleSignInAccount account) {
Fitness.getHistoryClient(DashBoardActivity.this, account)
.readData(readRequest)
.addOnSuccessListener(response -> {
if (response.getBuckets() != null && !response.getBuckets().isEmpty()) {
List bucketList = response.getBuckets();
if (bucketList != null && !bucketList.isEmpty()) {
for (Bucket bucket : bucketList) {
DataSet stepsDataSet = bucket.getDataSet(DataType.TYPE_STEP_COUNT_DELTA);
if (stepsDataSet != null) {
for (DataPoint dataPoint : stepsDataSet.getDataPoints()) {
String googleFitValue =dataPoint.getValue(Field.FIELD_STEPS).toString();
Log.i(TAG, "Value Steps : " +googleFitValue);
}
}
}
}
}
})
.addOnFailureListener(e -> {
Log.d(TAG, "onFailure : " + e.getLocalizedMessage());
CommonUtil.closeProgressDialog();
});
}

In the code above I have mentioned the static data for the start date. Let me explain to you why I have mentioned the static date for the start time. Google Fit launched the first version on 24 October 2014. So you can get the data from this date so I have mentioned the static date.

Now We Will Discuss How Can You Get Today’s Data

You can get today’s data that means from day starting 12 Am to now.

private void getTodaySData() {
Fitness.getHistoryClient(DashBoardActivity.this, getGoogleAccount())
.readDailyTotal(DataType.TYPE_STEP_COUNT_DELTA)
.addOnSuccessListener(new OnSuccessListener() {
@Override
public void onSuccess(DataSet dataSet) {
if (dataSet != null) {
List dataPoints = dataSet.getDataPoints();
for (DataPoint dataPoint : dataPoints) {
String googleFitValue =dataPoint.getValue(Field.FIELD_STEPS).toString();
Log.i(TAG, "Value Steps : " +googleFitValue);
}
}
}
});
}

If you are implementing google fit for live data as Google fit application is providing. Then you should call the above method in some time interval. Because there is no listener to get any callback which can notify you that data got updated on the server. So you have to call the above method to get the updated data.

Here I have mentioned code snippets only for the STEPS. There are many DataType available in google fit Using all these data types you can get the data like distance, calories, etc.
