android使用okhttp总是报错，代码在java工程中运行没有问题

Question

报错如下：

代码如下：

public class httpRequest {
OkHttpClient client = new OkHttpClient();

String run(String url) throws IOException {
    Request request = new Request.Builder().url(url).build();
    Response response = client.newCall(request).execute();
    if (response.isSuccessful()) {
        return response.body().string();
    } else {
        throw new IOException("Unexpected code " + response);
    }
}

}

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    tv = (TextView) findViewById(R.id.tt);
    httpRequest request = new httpRequest();
    try {
        String response = request.run("https://www.baidu.com");
        tv.setText(response);
        System.out.println(response);
        Log.d("res", response);
    } catch (IOException e) {
        // TODO Auto-generated catch block
        Log.d("error", "error!!!!!");
        e.printStackTrace();
    }
}

用okhttp3也是这样，提示找不到okhttp.okHttpClient

Answer 1

android專案裡面有沒有導入okHttp的包啊？報錯訊息指明了OkHttpClient這個類別沒有找到啊

Answer 2

你是導入jar包還是直接compile裡加的？

Answer 3

使用okhttp的時候還要再增加一個套件的依賴

compile 'com.squareup.okio:okio:1.5.0'

Answer 4

1、DexPathList中的dex中未包含okhttpclient，說明你打包的時候，沒有把okhttp的依賴包打進apk中
2、建議從eclipse轉到android studio
