在Android上使用Appium无法使用滑动功能

Question

package Android;

import org.openqa.selenium.By;

import io.appium.java_client.android.AndroidDriver;

public class driverSwipe {
AndroidDriver driver;
Dimension size;

@BeforeTest
public void setUp() throws Exception {
    DesiredCapabilities capabilities = new DesiredCapabilities();
    capabilities.setCapability("deviceName", "EUEQLZCI8TL7MFNB");
    capabilities.setCapability("browserName", "Android");
    capabilities.setCapability("platformVersion", "5.1");
    capabilities.setCapability("platformName", "Android");
    capabilities.setCapability("appPackage", "com.fortysevendeg.android.swipelistview");
    capabilities.setCapability("appActivity", "com.fortysevendeg.android.swipelistview.sample.activities.SwipeListViewExampleActivity");
    driver = new AndroidDriver(new URL("http://0.0.0.0:4723/wd/hub"), capabilities);
    driver.manage().timeouts().implicitlyWait(15, TimeUnit.SECONDS);
    WebDriverWait wait = new WebDriverWait(driver, 300);
    wait.until(ExpectedConditions.elementToBeClickable(By.className("android.widget.RelativeLayout")));
}

@Test
public void swipingHorizontal() throws InterruptedException {
    //Get the size of screen.
    size = driver.manage().window().getSize();
    System.out.println(size);

    //Find swipe start and end point from screen's with and height.
    //Find startx point which is at right side of screen.
    int startx = (int) (size.width * 0.70);
    //Find endx point which is at left side of screen.
    int endx = (int) (size.width * 0.30);
    //Find vertical point where you wants to swipe. It is in middle of screen height.
    int starty = size.height / 2;
    System.out.println("startx = " + startx + " ,endx = " + endx + " , starty = " + starty);

    //Swipe from Right to Left.
    driver.swipe(startx, starty, endx, starty, 3000);
    Thread.sleep(2000);

    //Swipe from Left to Right.
    driver.swipe(endx, starty, startx, starty, 3000);
    Thread.sleep(2000);
}

@Test
public void swipingVertical() throws InterruptedException {
    //Get the size of screen.
    size = driver.manage().window().getSize();
    System.out.println(size);

    //Find swipe start and end point from screen's with and height.
    //Find starty point which is at bottom side of screen.
    int starty = (int) (size.height * 0.80);
    //Find endy point which is at top side of screen.
    int endy = (int) (size.height * 0.20);
    //Find horizontal point where you wants to swipe. It is in middle of screen width.
    int startx = size.width / 2;
    System.out.println("starty = " + starty + " ,endy = " + endy + " , startx = " + startx);

    //Swipe from Bottom to Top.
    driver.swipe(startx, starty, startx, endy, 3000);
    Thread.sleep(2000);
    //Swipe from Top to Bottom.
    driver.swipe(startx, endy, startx, starty, 3000);
    Thread.sleep(2000);
}

@AfterTest
public void End() {
    driver.quit();
}

}

这是我用于在android中开发滑动列表视图应用程序的代码。我收到UnreachableBrowserException的错误：错误和WebDriverException。下面是logcat。

exception FAILED CONFIGURATION:@BeforeTestsetUp
1)org.openqa.selenium.remote.UnreachableBrowserException:Error communicating with the remote browser.It may have died.
2)Caused by:org.openqa.selenium.WebDriverException:No command or response codec has been defined.Unable to proceed.

任何人都可以帮我解决错误吗？
