代码：

package org.newlight.appiumDemo;

import io.appium.java_client.AppiumDriver;

import java.io.File;
import java.net.URL;
import java.util.List;

import org.junit.After;
import org.junit.Before;
import org.junit.Test;
import org.openqa.selenium.By;
import org.openqa.selenium.Capabilities;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.interactions.HasTouchScreen;
import org.openqa.selenium.interactions.TouchScreen;
import org.openqa.selenium.remote.CapabilityType;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.openqa.selenium.remote.RemoteTouchScreen;
import org.openqa.selenium.remote.RemoteWebDriver;

public class CopyOfAndroidContactsTest {
    private AppiumDriver driver;

    @Before
    public void setUp() throws Exception {
        File classpathRoot = new File(System.getProperty("user.dir"));
        File appDir = new File(classpathRoot, "apps/ContactManager");
        File app = new File(appDir, "ContactManager.apk");
        DesiredCapabilities capabilities = new DesiredCapabilities();
        capabilities.setCapability("device", "Android");
        capabilities.setCapability(CapabilityType.BROWSER_NAME, "");
        capabilities.setCapability(CapabilityType.VERSION, "4.4");
        capabilities.setCapability(CapabilityType.PLATFORM, "WINDOWS");
        capabilities.setCapability("app", app.getAbsolutePath());
        capabilities.setCapability("app-package",
                "com.example.android.contactmanager");
        capabilities.setCapability("app-activity", ".ContactManager");
                driver = new AppiumDriver(new URL("http://127.0.0.1:4723/wd/hub"), capabilities);
    }

    @Test
    public void addContact() {
        WebElement el = driver.findElement(By.name("Add Contact"));
        el.click();
        List<WebElement> textFieldsList = driver.findElements(By.tagName("textfield"));
        textFieldsList.get(0).sendKeys("Some Name");
        textFieldsList.get(2).sendKeys("Some@example.com");
        driver.findElement(By.name("Save")).click();
    }
}

运行结果如下：

报错语句为： AppiumDriver dr = new AppiumDriver(new URL("http://127.0.0.1:4723/wd/hub"), capabilities);

引入的包有：

测试机器：
模拟器：安卓 4.4
真机：安卓 4.4

而，使用 webdriver 是正常的:

package org.newlight.appiumDemo;

import org.junit.Before;
import org.junit.Test;

import org.openqa.selenium.interactions.HasTouchScreen;
import org.openqa.selenium.interactions.TouchScreen;
import org.openqa.selenium.remote.CapabilityType;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.openqa.selenium.remote.RemoteTouchScreen;
import org.openqa.selenium.remote.RemoteWebDriver;

public class AndroidContactsTest {
    private WebDriver driver;

    @Before
    public void setUp() throws Exception {
        // set up appium
        File classpathRoot = new File(System.getProperty("user.dir"));
        File appDir = new File(classpathRoot, "apps/ContactManager");
        File app = new File(appDir, "ContactManager.apk");
        DesiredCapabilities capabilities = new DesiredCapabilities();
        capabilities.setCapability("device", "Android");
        capabilities.setCapability(CapabilityType.BROWSER_NAME, "");
        capabilities.setCapability(CapabilityType.VERSION, "4.4");
        capabilities.setCapability(CapabilityType.PLATFORM, "WINDOWS");
        capabilities.setCapability("app", app.getAbsolutePath());
        capabilities.setCapability("app-package",
                "com.example.android.contactmanager");
        capabilities.setCapability("app-activity", ".ContactManager");
        driver = new SwipeableWebDriver(
                new URL("http://127.0.0.1:4723/wd/hub"), capabilities);
    }

    @Test
    public void addContact() {
        WebElement el = driver.findElement(By.name("Add Contact"));
        el.click();
        List<WebElement> textFieldsList = driver.findElements(By
                .tagName("textfield"));
        textFieldsList.get(0).sendKeys("Some Name");
        textFieldsList.get(2).sendKeys("Some@example.com");
        driver.findElement(By.name("Save")).click();
    }

    public class SwipeableWebDriver extends RemoteWebDriver implements
            HasTouchScreen {
        private RemoteTouchScreen touch;

        public SwipeableWebDriver(URL remoteAddress,
                Capabilities desiredCapabilities) {
            super(remoteAddress, desiredCapabilities);
            touch = new RemoteTouchScreen(getExecuteMethod());
        }

        public TouchScreen getTouch() {
            return touch;
        }
    }
}

你不 @ 我，我就不告诉你。。 把 javaclient 回滚到 1.2.1

把 selenium-java-2.41.0.jar 换成 2.42 版本的

匿名 #3 · 2014年07月24日

多谢各位，找到问题所在了，是因为 junit4.11 版本太高，要加多一个 hamcrest-core-1.3.jar

xiayuxiamo #4 · 2014年08月08日

#3 楼 @liqing380 你好，请问你怎么引入的 hamcrest-core-1.3.jar 包，我引入之后还是报同样的错误。。。

遇到同样的问题，关键在 jenkins 上运行的时候还不报错。搞了半天，升级 selenium
jar 的时候，把所依赖的其他包一起升掉。不然会有问题

前面都执行成功啦，就 执行这一步的时候
List textFieldsList = driver.findElements(BytagName("textfield"));
没有输入东西反而直接返回桌面了呢
