Here is the code sample I am trying to use. Its from a tutorial online (teamtreehouse.com) Java code:
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);

OkHttp needs Okio, which OkHttp uses for fast I/O and resizable buffers. You can download Okio (latest JAR) here.
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。你可以在这里下载 Okio（最新的 JAR）。

There seems to be a dependency on the 1.0 library of OkHTTP. It is a known report. You may follow it on the link below:
似乎依赖于 OkHTTP 的 1.0 库。这是一个众所周知的报告。您可以通过以下链接关注它：
https://github.com/square/okhttp/issues/870
https://github.com/square/okhttp/issues/870
You should also include the library 1.0in the project libs.
您还应该在项目库中包含库 1.0。
