Android Google Fitness startSession中可能存在竞争条件或程序员错误

我试图在我的裁判表中记录体育活动期间的Google Fit训练。我在周期开始时开始一个会话，然后在周期结束时停止它

当我使用以下代码开始健身课程时，有时会遇到一个有趣的异常：

       private Session startFitSession(final Game currentGame) {
        final Session fitSession;
        try {
            String sessionBaseName =  currentGame.getGameTitle();
            if (sessionBaseName.isEmpty()) sessionBaseName = currentGame.getGameLocation();
            if (sessionBaseName.isEmpty()) sessionBaseName = RefWatchUtil.timeMsToString(currentGame.getActualStartMs(),RefWatchUtil.dateTimeFormatStart);

            final String sessionName = sessionBaseName +  ": "
                    + String.format(getResources().getString(R.string.fitness_period_label),mCurrentPeriod);
            //use this to try to avoid error message about creating a session in the future
            final long startTime = System.currentTimeMillis()-TimeUnit.SECONDS.toMillis(10);
            fitSession = new Session.Builder()
                    .setName(sessionName)
                    .setIdentifier(sessionName)
                    .setDescription(mCurrentGame.getGameDescription())
                    .setStartTime(startTime, TimeUnit.MILLISECONDS)
                    .setActivity(FitnessActivities.RUNNING_JOGGING)
                    .build();

            Fitness.SessionsApi.startSession(mGoogleApiClient, fitSession)
                .setResultCallback(new ResultCallback<Status>() {
                    @Override
                    public void onResult(@NonNull Status status) {
                        if (status.isSuccess()) {
                            Log.i(TAG, "Successfully started Session " + sessionName);
                        } else {
                            Log.i(TAG, "There was a problem starting the session " + sessionName
                                    + ": " + status.getStatusMessage());
                        }
                    }
            });

        } catch (RuntimeException e){
            Log.i(TAG, "There was a runtime exception starting the session: " + e.getLocalizedMessage());
            return null;
        }
        return fitSession;
    }

同样的错误

现在我从开始时间中减去任意10秒，这似乎解决了问题

但是（a）是否有更好的方法进行此调用（afaict，您不能使用0参数调用setStartTime以获取“当前时间”）和（b）这是生成器类型调用的常见模式？

嘿，您找到相同的解决方案了吗？嘿，您找到相同的解决方案了吗？

 ...
 final long startTime = System.currentTimeMillis();
            fitSession = new Session.Builder()
                    .setName(sessionName)
                    .setIdentifier(sessionName)
                    .setDescription(mCurrentGame.getGameDescription())
                    .setStartTime(startTime, TimeUnit.MILLISECONDS)
