从 Google Fit 获取第三方应用程序（Sleep as Android）数据

Question

我目前正试图在我自己的 Android 应用程序中从 Google Fit 获取 Sleep as Android 数据。我从一篇文章中读到，Android 数据存储在 Google Fit 中，任何第三方应用程序都可以查看它们。为此，我使用历史会话。这是读取睡眠数据的示例代码：

public static DataReadRequest queryFitnessData() {
    // [START build_read_data_request]
    // Setting a start and end date using a range of 1 week before this moment.
    Calendar cal = Calendar.getInstance();
    Date now = new Date();
    cal.setTime(now);
    long endTime = cal.getTimeInMillis();
    cal.add(Calendar.WEEK_OF_YEAR, -1);
    long startTime = cal.getTimeInMillis();

    java.text.DateFormat dateFormat = getDateInstance();
    Log.i(TAG, "Range Start: " + dateFormat.format(startTime));
    Log.i(TAG, "Range End: " + dateFormat.format(endTime));

    DataReadRequest readRequest = new DataReadRequest.Builder()
            .read(DataType.TYPE_ACTIVITY_SEGMENT)
            .setTimeRange(startTime, endTime, TimeUnit.MILLISECONDS)
            .build();
    // [END build_read_data_request]

    return readRequest;
}

并执行该查询：

DataReadRequest readRequest = queryFitnessData();
DataReadResult dataReadResult = Fitness.HistoryApi.readData(
        mClient, readRequest).await(1, TimeUnit.MINUTES);
printData(dataReadResult);

我的猜测是我错过了一些东西。我还阅读了 this 关于同一主题的帖子，但直到现在都没有成功。

终于，我明白了。感谢 Urbandroid 团队的 Martin Stava。

final SessionReadRequest.Builder sessionBuilder = new SessionReadRequest.Builder()

        .setTimeInterval(startTime, endTime, TimeUnit.MILLISECONDS)
        .read(DataType.TYPE_ACTIVITY_SEGMENT)
        .readSessionsFromAllApps()
        .enableServerQueries();

final SessionReadRequest readRequest = sessionBuilder.build();

// Invoke the Sessions API to fetch the session with the query and wait for the result
// of the read request.
SessionReadResult sessionReadResult = SessionsApi.readSession(apiClient, readRequest).await(120, TimeUnit.SECONDS);

Status status = sessionReadResult.getStatus();
