I am currently trying to work with Google Fit API.This is my first App using the API, and I have been mainly by following Google's documentation.
Below is the code that I have which seems to have a problem
The problem I have is that it doesn't seem to be updating the step counter.
public class MainActivity extends Activity
implements GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener {
private static final String TAG = "FitActivity";
//[START Auth_Variable_References]
private static final int REQUEST_OAUTH = 1;
// [END auth_variable_references]
private GoogleApiClient mClient = null;
int mInitialNumberOfSteps = 0;
private TextView mStepsTextView;
private boolean mFirstCount = true;
// Create Builder View
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mStepsTextView = (TextView) findViewById(R.id.textview_number_of_steps);
}
private void connectFitness() {
Log.i(TAG, "Connecting...");
// Create the Google API Client
mClient = new GoogleApiClient.Builder(this)
// select the Fitness API
.addApi(Fitness.API)
// specify the scopes of access
.addScope(new Scope(Scopes.FITNESS_ACTIVITY_READ))
.addScope(new Scope(Scopes.FITNESS_LOCATION_READ))
.addScope(new Scope(Scopes.FITNESS_BODY_READ_WRITE))
// provide callbacks
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.build();
// Connect the Google API client
mClient.connect();
}
// Manage OAuth authentication
@Override
public void onConnectionFailed(ConnectionResult result) {
// Error while connecting. Try to resolve using the pending intent returned.
if (result.getErrorCode() == ConnectionResult.SIGN_IN_REQUIRED ||
result.getErrorCode() == FitnessStatusCodes.NEEDS_OAUTH_PERMISSIONS) {
try {
// Request authentication
result.startResolutionForResult(this, REQUEST_OAUTH);
} catch (IntentSender.SendIntentException e) {
Log.e(TAG, "Exception connecting to the fitness service", e);
}
} else {
Log.e(TAG, "Unknown connection issue. Code = " + result.getErrorCode());
}
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_OAUTH) {
if (resultCode == RESULT_OK) {
// If the user authenticated, try to connect again
mClient.connect();
}
}
}
@Override
public void onConnectionSuspended(int i) {
// If your connection gets lost at some point,
// you'll be able to determine the reason and react to it here.
if (i == GoogleApiClient.ConnectionCallbacks.CAUSE_NETWORK_LOST) {
Log.i(TAG, "Connection lost. Cause: Network Lost.");
} else if (i == GoogleApiClient.ConnectionCallbacks.CAUSE_SERVICE_DISCONNECTED) {
Log.i(TAG, "Connection lost. Reason: Service Disconnected");
}
}
@Override
public void onConnected(Bundle bundle) {
Log.i(TAG, "Connected!");
// Now you can make calls to the Fitness APIs.
invokeFitnessAPIs();
}
private void invokeFitnessAPIs() {
// Create a listener object to be called when new data is available
OnDataPointListener listener = new OnDataPointListener() {
@Override
public void onDataPoint(DataPoint dataPoint) {
for (Field field : dataPoint.getDataType().getFields()) {
Value val = dataPoint.getValue(field);
updateTextViewWithStepCounter(val.asInt());
}
}
};
//Specify what data sources to return
DataSourcesRequest req = new DataSourcesRequest.Builder()
.setDataSourceTypes(DataSource.TYPE_DERIVED)
.setDataTypes(DataType.TYPE_STEP_COUNT_DELTA)
.build();
// Invoke the Sensors API with:
// - The Google API client object
// - The data sources request object
PendingResult<DataSourcesResult> pendingResult =
Fitness.SensorsApi.findDataSources(mClient, req);
// Build a sensor registration request object

// 4. Check the result asynchronously
regResult.setResultCallback(new ResultCallback<Status>()
{
@Override
public void onResult(Status status) {
if (status.isSuccess()) {
Log.d(TAG, "listener registered");
// listener registered
} else {
Log.d(TAG, "listener not registered");
// listener not registered
}
}
});
}
// Update the Text Viewer with Counter of Steps..
private void updateTextViewWithStepCounter(final int numberOfSteps) {
runOnUiThread(new Runnable() {
@Override
public void run() {
Toast.makeText(getBaseContext(), "On Datapoint!", Toast.LENGTH_SHORT);
if(mFirstCount && (numberOfSteps != 0)) {
mInitialNumberOfSteps = numberOfSteps;
mFirstCount = false;
}
if(mStepsTextView != null){
mStepsTextView.setText(String.valueOf(numberOfSteps - mInitialNumberOfSteps));
}
}
});
}
//Start
@Override
protected void onStart() {
super.onStart();
mFirstCount = true;
mInitialNumberOfSteps = 0;
if (mClient == null || !mClient.isConnected()) {
connectFitness();
}
}
//Stop
@Override

super.onStop();
if(mClient.isConnected() || mClient.isConnecting()) mClient.disconnect();
mInitialNumberOfSteps = 0;

}
First of all, Follow these steps to enable the Fitness API in the Google API Console and get an OAuth 2.0 client ID.
1. Go to the Google API Console.
2. Select a project, or create a new one. Use the same project for the Android and REST versions of your app.
3. Click Continue to enable the Fitness API.
4. Click Go to credentials.
5. Click New credentials, then select OAuth Client ID.
6. Under Application type select Android.
7. In the resulting dialog, enter your app's SHA-1 fingerprint and package name. For example:
BB:0D:AC:74:D3:21:E1:43:67:71:9B:62:91:AF:A1:66:6E:44:5D:75
com.example.android.fit-example
8. Click Create. Your new Android OAuth 2.0 Client ID and secret appear in the list of IDs for your project. An OAuth 2.0 Client ID is a string of characters, something like this:

NOTE : :: Sometimes in some device it doestn't detect Step values so whenever you are developing and workling with this code Always Uninstall app and then re-install app. then this works fine.
