Using google fit api from a backend server

Question

I\'m writing an android application which needs to read user\'s fitness data (steps, calories, etc) from a back end server. this server will read the data and push notifications

Answer 1

In case anyone needs this, there is javadoc available here. And here is a simple example of a batch request for the user's height and weight from the backend server:

GoogleCredential credential = new GoogleCredential().setAccessToken(activeUser.getAccessToken());

Fitness fitness = new Fitness.Builder(new NetHttpTransport(), 
                                      JacksonFactory.getDefaultInstance(), 
                                      credential)
        .setApplicationName("MyApp")
        .build();

BatchRequest batchRequest = new BatchRequest(new NetHttpTransport(), credential);
fitness.users()
        .dataSources()
        .datasets()
        .get("me", "derived:com.google.weight:com.google.android.gms:merge_weight",
                        String.format("0-%d", System.nanoTime()))
        .queue(batchRequest, new WeightRequestCallback(activeUser));

fitness.users()
        .dataSources()
        .datasets()
        .get("me", "derived:com.google.height:com.google.android.gms:merge_height",
                String.format("0-%d", System.nanoTime()))
        .queue(batchRequest, new HeightRequestCallback(activeUser));


batchRequest.execute();

HeightRequestCallback and WeightRequestCallback extend JsonBatchCallback<Dataset>
