10. How Google Fit Works
reference: https://developers.google.com/fit/overview

11. Components
• The Fitness Store
• The Sensor Framework
• Permissions and User Controls
• Google Fit APIs
Main Components of Google Fit

12. Points of Today
Focus on Fitness APIs
reference: https://developers.google.com/fit/android/
• Sensor API
• Record API
• History API
• Session API
• Others(BLE, Config APIs)

13. Before Discussing APIs
There are 3 Fitness Data Types
• Public Data Types
• Private Custom Data Types
• Shareable Data Types

14. Fitness APIs
Sensor API
reference: https://developers.google.com/fit/android/
• read Raw Sensor in Real Time
• list Data Sources
• use Listeners

15. Fitness APIs
reference: https://developers.google.com/fit/android/
• store Data of Sensor by Subscriptions.
• use Multiple Subscriptions at the same time
• the Data Stored will be Here Used from History API
Record API

16. Fitness APIs
reference: https://developers.google.com/fit/android/
• can Use Reading, Inserting and Deleting Data
• can Use Synchronously and Asynchronously
• arrange Period Freely
History API

17. Fitness APIs
Session API
reference: https://developers.google.com/fit/android/
• create Session with Record API
• read Fitness Data Using Session
• show Sessions in Other Apps
• use Session Broadcast Intents

18. Preparation
reference: https://developers.google.com/fit/android/
• Install Google Play Services
• Get a Google Account
• Create an OAuth Client ID
• Register the Public Certificate
• Add Google Play Service in Build Gradle
• Enjoy Fit APIs !!

22. Steps
Step2 Use Location API
Step1 Create Google API Client
• add API Types
• add Scopes(Permission)
• add Callbacks

23. Step1 Create Google API Client
private void buildFitnessClient() {
mClient = new GoogleApiClient.Builder(this)
// can add multiple api types
.addApi(Fitness.SENSORS_API)
.addApi(Fitness.RECORDING_API)
.addApi(Fitness.HISTORY_API)
// can add multiple scopes
.addScope(new Scope(Scopes.FITNESS_ACTIVITY_READ_WRITE))
.addScope(new Scope(Scopes.FITNESS_LOCATION_READ))
.addScope(new Scope(Scopes.FITNESS_ACTIVITY_READ_WRITE))
.addScope(new Scope(Scopes.FITNESS_BODY_READ_WRITE))
//
.addConnectionCallbacks(
new GoogleApiClient.ConnectionCallbacks() {
@Override
public void onConnected(Bundle bundle) {
Log.i(TAG, "Connected!!!");
// use fitness apis freely!!
}
@Override
public void onConnectionSuspended(int i) {
}
}
)
.addOnConnectionFailedListener(
new GoogleApiClient.OnConnectionFailedListener() {
// Called whenever the API client fails to connect.
@Override
public void onConnectionFailed(ConnectionResult result) {
}
}
)
.build();
}

24. Step2 Use Location API
Fitness.SensorsApi.findDataSources(mClient, new DataSourcesRequest.Builder()
// at least one datatype must be specified.
.setDataTypes(DataType.TYPE_LOCATION_SAMPLE)
.setDataSourceTypes(DataSource.TYPE_RAW)
.build())
.setResultCallback(new ResultCallback<DataSourcesResult>() {
@Override
public void onResult(DataSourcesResult dataSourcesResult) {
for (DataSource dataSource : dataSourcesResult.getDataSources()) {
Log.i(TAG, "Data source found: " + dataSource.toString());
Log.i(TAG, "Data Source type: " + dataSource.getDataType().getName());
if (dataSource.getDataType().equals(DataType.TYPE_LOCATION_SAMPLE)
&& mListener == null) {
Log.i(TAG, "Data source for LOCATION_SAMPLE found! Registering.");
registerFitnessDataListener(dataSource, DataType.TYPE_LOCATION_SAMPLE);
}
}
}
});

25. Step2 Use Location API
private OnDataPointListener mListener;
private float latitude, longitude, altitude, accuracy;
private void registerFitnessDataListener(DataSource dataSource, DataType dataType) {
mListener = new OnDataPointListener() {
@Override
public void onDataPoint(DataPoint dataPoint) {
for (Field field : dataPoint.getDataType().getFields()) {
final Value val = dataPoint.getValue(field);
Log.i(TAG, "Detected DataPoint field: " + field.getName());
Log.i(TAG, "Detected DataPoint value: " + val);
switch (field.getName()) {
case "latitude":
latitude = val.asFloat();
break;
case "longitude":
longitude = val.asFloat();
break;
case "altitude":
altitude = val.asFloat();
break;
case "accuracy":
accuracy = val.asFloat();
break;
}
}
runOnUiThread(new Runnable() {
@Override
public void run() {
latitudeView.setText(String.valueOf(latitude));
longitudeView.setText(String.valueOf(longitude));
altitudeView.setText(String.valueOf(altitude));
accuracyView.setText(String.valueOf(accuracy));
}
});
}
};
//register listener
