这是我尝试使用的代码示例。它来自在线教程（teamtreehouse.com） Java 代码：

OkHttpClient client = new OkHttpClient();
            Request request = new Request.Builder()
                    .url(forecastUrl)
                    .build();

            Call call = client.newCall(request);
            call.enqueue(new Callback() 
                @Override
                public void onFailure(Request request, IOException e) 
                    runOnUiThread(new Runnable() 
                        @Override
                        public void run() 
                            toggleRefresh();
                        
                    );
                    alertUserAboutError();
                

                @Override
                public void onResponse(Response response) throws IOException 
                    runOnUiThread(new Runnable() 
                        @Override
                        public void run() 
                            toggleRefresh();
                        
                    );

                    try 
                        String jsonData = response.body().string();
                        Log.v(TAG, jsonData);
                        if (response.isSuccessful()) 
                            mCurrentWeather = getCurrentDetails(jsonData);
                            runOnUiThread(new Runnable() 
                                @Override
                                public void run() 
                                    updateDisplay();
                                
                            );
                         else 
                            alertUserAboutError();
                        
                    
                    catch (IOException e) 
                        Log.e(TAG, "Exception caught: ", e);
                    
                    catch (JSONException e) 
                        Log.e(TAG, "Exception caught: ", e);
                    
                
            );

【参考方案1】：

OkHttp 需要 Okio，OkHttp 使用它来实现快速 I/O 和可调整大小的缓冲区。您可以下载 Okio（最新 JAR）here。

或

安卓毕业：compile 'com.squareup.okio:okio:1.6.0'

马文

<dependency>
    <groupId>com.squareup.okio</groupId>
    <artifactId>okio</artifactId>
    <version>1.6.0</version>
</dependency>

for version checks; github okio

【参考方案2】：

似乎对 OkHTTP 的 1.0 库有依赖。这是一个已知的报告。您可以通过以下链接关注它：

https://github.com/square/okhttp/issues/870

您还应该在项目库中包含library 1.0。
