URL无法解析为appium中的类型

Question

这是什么错误？ 我使用了这段代码，但它没有运行

package AppiumTest;

import org.openqa.selenium.remote.DesiredCapabilities;
import org.testng.annotations.Test;

import io.appium.java_client.android.AndroidDriver;

public class myAppiumTest {

    @SuppressWarnings("rawtypes")
    AndroidDriver dr;
    @SuppressWarnings("rawtypes")
    @Test
    public void call() {

        DesiredCapabilities caps = new DesiredCapabilities();
        caps.setCapability("deviceName","Honor 6x");
        caps.setCapability("platformVersion", "7.0");
        caps.setCapability("platformName", "Android");
        caps.setCapability("appPackage", "com.youdao.hindict");
        caps.setCapability("appActivity", "com.youdao.hindict.activity.LockScreenActivity");

        dr = new AndroidDriver(new URL("http://127.0.0.1:4723/wd/hub/"), "caps");
    }
}
