Android 无法解析构造函数生成器（）

使用okhttp
我在new Request.Builder（）行上遇到无法解析构造函数错误

错误跟踪在哪里？@YosiPramajaya什么？我是android studio的初学者，请帮助@YosiPramajaya发布堆栈跟踪是最好的做法，让别人有最好的机会帮助你，因为仅仅说“我有x个错误”恐怕没有多大帮助。也许你需要

导入okhttp3。请求
；
public final OkHttpClient client = new OkHttpClient();

public void run() throws Exception {
    Request request = new Request.Builder()
            .url("https://publicobject.com/helloworld.txt")
            .build();

    try (Response response = client.newCall(request).execute()) {
        if (!response.isSuccessful()) throw new IOException("Unexpected code " + response);

        Headers responseHeaders = response.headers();
        for (int i = 0; i < responseHeaders.size(); i++) {
            System.out.println(responseHeaders.name(i) + ": " + responseHeaders.value(i));
        }

        System.out.println(response.body().string());
    }
}

import okhttp3.Headers;
import okhttp3.OkHttpClient;
import okhttp3.RequestBody;
import okhttp3.Response;
