谷歌健身历史readData()没有给出结果

Question

我一直在使用传感器来检测步骤，并希望将源更改为历史记录（我想今天获得总步骤）。我遵循了多个堆栈溢出和教程（大部分是谷歌自己的）。这是我的代码，它在一个粘性服务中创建的类中。

private void buildFitnessClient() {
    mClient = new GoogleApiClient.Builder(context)
            .addApi(Fitness.HISTORY_API)
            .build();
    mClient.connect();
    DataReadRequest readRequest = new DataReadRequest.Builder()
            .aggregate(DataType.TYPE_STEP_COUNT_DELTA, DataType.AGGREGATE_STEP_COUNT_DELTA)
            .bucketByTime(1, TimeUnit.DAYS)
            .setTimeRange(
                    DateTime.now().minusDays(5).getMillis(),
                    DateTime.now().getMillis(),
                    TimeUnit.MILLISECONDS)
            .build();
    Fitness.HistoryApi.readData(mClient, readRequest).setResultCallback(new ResultCallback<DataReadResult>() {
        @Override
        public void onResult(DataReadResult dataReadResult) {
            Log.d(TAG, "onResult");
            Log.d(TAG, "" + dataReadResult.getBuckets().size());
            for (Bucket bucket : dataReadResult.getBuckets()) {
                List<DataSet> dataSets = bucket.getDataSets();
                for (DataSet dataSet : dataSets) {
                    Log.d(TAG, "dataSet.dataType: " + dataSet.getDataType().getName());
                    for (DataPoint dp : dataSet.getDataPoints()) {
                        Log.d(TAG, "dp:" + dp.toString());
                    }
                }
            }
        }
    });
    Log.d(TAG, "Dataset in History end ");
}

从本质上讲，什么都没发生。我看不到日志"onResult"。怎么了？是客户端构建的吗？背景？参数？

谢谢！

答案是我没有适当的权限。我更改了一些类并删除了应用程序数据，因此我失去了权限，也没有任何恢复它们的措施。

所以，需要什么：

检查api客户端是否已连接（使用addOnConnectionFailedListener），如果连接失败，请运行类似以下的代码：

    //ConnectionResult result = intent.getExtras().getParcelable(OrderKeys.FITNESS_CONNECTION_FAILED_RESULT);
// This is my solution for service-activty communication, this is run in activty
            Log.i(TAG, "Connection failed. Cause: " + result.toString());
            if (!result.hasResolution()) {
                // Show the localized error dialog
                GooglePlayServicesUtil.getErrorDialog(result.getErrorCode(),
                        LifeAidActivity.this, 0).show();
                return;
            }
            // The failure has a resolution. Resolve it.
            // Called typically when the app is not yet authorized, and an
            // authorization dialog is displayed to the user.
            if (!authInProgress) {
                try {
                    Log.i(TAG, "Attempting to resolve failed connection");
                    authInProgress = true;
                    result.startResolutionForResult(LifeAidActivity.this,
                            REQUEST_OAUTH);
                } catch (IntentSender.SendIntentException e) {
                    Log.e(TAG,
                            "Exception while starting resolution activity", e);
                }
            }
