我做了以下事情:

1.注册 Yelp API

1. Registered for Yelp API

2. 下载了 scribe 1.3.0，并将其添加到 libs 文件夹

2. Downloaded scribe 1.3.0, and added it to the libs folder

3. 添加了两个类 Yelp.java 和 YelpApi2.java 到 src 文件夹

3. Added two classes Yelp.java and YelpApi2.java to the src folder

4. 从 Yelp API 中删除了 main 函数，并将 Yelp 调用添加到我的主要活动中.

4. Removed the main function from Yelp API and I have added the Yelp call to my main activity.

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_hello_world);

    // Update tokens here from Yelp developers site, Manage API access.
    String consumerKey = "secret";
    String consumerSecret = "secret";
    String token = "secret";
    String tokenSecret = "secret";

    Yelp yelp = new Yelp(consumerKey, consumerSecret, token, tokenSecret);
    String response = yelp.search("burritos", 30.361471, -87.164326);

}

(当然，secret 是我从 Yelp 获得的实际信息)

(Of course, were secret is my actual information from Yelp)

我对 Android 比较陌生，所以我觉得这很简单，但我不太清楚问题所在，因为我遵循了 Yelp 的示例和 这篇文章完全正确.

I am rather new to Android, so I have a feeling it is something simple, but I can't quite figure out the issue, as I have followed Yelp's examples and this post exactly.

推荐答案

异常的名称非常清楚:您正试图从主 (UI) 线程访问网络.应保留 UI 线程来处理 UI 事件，以确保您的应用不会停止响应，并且您应该在后台线程上执行其他任务(如网络或计算).

The name of the exception is pretty clear: You're trying to access the network from the main (UI) thread. The UI thread should be reserved for handling UI events to ensure that your app doesn't stop responding, and you should perform other tasks (like networking or calculations) on a background thread.
