致命异常:与doInBackground()相关的AsyncTask #1

Question

当我运行我的代码时，我得到一个致命的异常: AsyncTask #1。日志告诉我这是由指向com.google.api.client.http.HttpHeaders.set的NoSuchMethodError引起的。我使用的是针对Android的实际java驱动程序，当运行该代码时，我得到了这个错误。

为什么我会得到这个？我能做些什么来解决这个问题？

以下是错误所指向的代码：

    @Override
    protected List<ReadResponse> doInBackground(Query... params) {
        List<ReadResponse> results = Lists.newArrayList(); 
        for (Query q : params) {
            results.add(factual.fetch("restaurants-us", q));
        }
        return results;
    }

我得到的错误日志是：

任何帮助是非常感谢，请让我知道，如果我能提供任何其他。谢谢!

看起来你的库实际调用了一个不存在的函数。你确定它能在你的Android版本上工作吗？
