How Google Fit Works

reference: https://developers.google.com/fit/overview

Components

• The Fitness Store

• The Sensor Framework

• Permissions and User Controls

• Google Fit APIs

Main Components of Google Fit

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)

Before Discussing APIs

There are 3 Fitness Data Types

• Public Data Types

• Private Custom Data Types

• Shareable Data Types

Fitness APIs

Sensor API

reference: https://developers.google.com/fit/android/

• read Raw Sensor in Real Time

• list Data Sources

• use Listeners

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

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

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

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 !!

Steps

Step2 Use Location API

Step1 Create Google API Client

• add API Types • add Scopes(Permission) • add Callbacks

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(); }

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); } } } });

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
