在服務中獲取每日步數數據（Google健身歷史記錄API）

Question

我想實現一項服務，該服務每小時獲取一次每日步長數據以執行此操作。

我使用MyGoogleApiClient_Singleton實例和MainActivity將客戶端傳遞給服務。

我的主要活動

public class MainActivity extends AppCompatActivity {
public static final String TAG = "StepCounter";
private GoogleApiClient mClient = null;
TextView tv;
long total;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    // This method sets up our custom logger, which will print all log messages to the device
    // screen, as well as to adb logcat.
    initializeLogging();

    buildFitnessClient();

    tv=(TextView)findViewById(R.id.title_text_view);

    //inicializamos el servicio
    startService(new Intent(this, DatabaseUpload.class));

}

/**
 * Build a {@link GoogleApiClient} to authenticate the user and allow the application
 * to connect to the Fitness APIs. The included scopes should match the scopes needed
 * by your app (see the documentation for details).
 * Use the {@link GoogleApiClient.OnConnectionFailedListener}
 * to resolve authentication failures (for example, the user has not signed in
 * before, or has multiple accounts and must specify which account to use).
 */
private void buildFitnessClient() {
    // Create the Google API Client
    mClient = new GoogleApiClient.Builder(this)
            .addApi(Fitness.RECORDING_API)
            .addApi(Fitness.HISTORY_API)
            .addScope(new Scope(Scopes.FITNESS_ACTIVITY_READ_WRITE))
            .addConnectionCallbacks(
                    new GoogleApiClient.ConnectionCallbacks() {

                        @Override
                        public void onConnected(Bundle bundle) {
                            Log.i(TAG, "Connected!!!");
                            // Now you can make calls to the Fitness APIs.  What to do?
                            // Subscribe to some data sources!
                            subscribe();

                            // you'll be able to determine the reason and react to it here.
                            if (i == ConnectionCallbacks.CAUSE_NETWORK_LOST) {
                                Log.w(TAG, "Connection lost.  Cause: Network Lost.");
                            } else if (i == ConnectionCallbacks.CAUSE_SERVICE_DISCONNECTED) {
                                Log.w(TAG, "Connection lost.  Reason: Service Disconnected");
                            }
                        }
                    }
            )
            .enableAutoManage(this, 0, new GoogleApiClient.OnConnectionFailedListener() {

                            new VerifyDataTask().execute();

                }
            });
}

    startActivity(new Intent(getBaseContext(), Cuenta.class)
            .addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP));
}

}

和我的服務（它什么也沒做）

public class DatabaseUpload extends Service {

GoogleApiClient mClient;
String TAG ="DataUpdate";

@Override
public void onCreate() {
    super.onCreate();

    mClient=MyGoogleApiClient_Singleton.getInstance(null).get_GoogleApiClient();

}

@Nullable
@Override
public IBinder onBind(Intent intent) {
    return null;
}

@Override
public int onStartCommand(Intent intent, int flags, int startId) {



    return super.onStartCommand(intent, flags, startId);
}

}

我不知道如何繼續，謝謝您的幫助

Answer 1

您可以參考以下相關的SO帖子： 如何從Google Fit API檢索日常跑步和步行步驟，以及如何 通過Google Fit Api檢索到的步數與Google Fit Official App中顯示的步數不匹配 。 您可以使用以下代碼獲取每天各種活動的步驟：

DataReadRequest readRequest = new DataReadRequest.Builder()
            .aggregate(ESTIMATED_STEP_DELTAS, DataType.AGGREGATE_STEP_COUNT_DELTA)
            .bucketByActivityType(1, TimeUnit.SECONDS)
            .setTimeRange(startTime, endTime, TimeUnit.MILLISECONDS)
            .build();

您也可以查看此文檔 ，該文檔演示了如何使用Fit Android API和Fit REST API讀取當前的每日步數數據。

您的應用可以通過調用[ HistoryApi.readDailyTotal ]（ https://developers.google.com/android/reference/com/google/android/gms/fitness/HistoryApi.html#readDailyTotal ( com.google .android.gms.common.api.GoogleApiClient ，com.google.android.gms.fitness.data.DataType）），如以下示例所示：

private class VerifyDataTask extends AsyncTask<Void, Void, Void> {
    protected Void doInBackground(Void... params) {

        long total = 0;

        PendingResult<DailyTotalResult> result = Fitness.HistoryApi.readDailyTotal(mClient, DataType.TYPE_STEP_COUNT_DELTA);
        DailyTotalResult totalResult = result.await(30, TimeUnit.SECONDS);
        if (totalResult.getStatus().isSuccess()) {
            DataSet totalSet = totalResult.getTotal();
            total = totalSet.isEmpty()
                    ? 0
                    : totalSet.getDataPoints().get(0).getValue(Field.FIELD_STEPS).asInt();
        } else {
            Log.w(TAG, "There was a problem getting the step count.");
        }

        Log.i(TAG, "Total steps: " + total);

        return null;
    }
}
