android使用okhttp总是报错，代码在java工程中运行没有问题

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

1、DexPathList中的dex中未包含okhttpclient，说明你打包的时候，没有把okhttp的依赖包打进apk中
2、建议从eclipse转到android studio

---

android项目里面有没有导入okHttp的包啊？报错信息指明了OkHttpClient这个类没有找到啊

---

使用okhttp的时候还要添加另外一个包的依赖

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

---

你是导入jar包还是直接compile里添加的？
