package org.newlight.appiumDemo;

import io.appium.java_client.AppiumDriver;

import java.util.List;

import org.junit.After;

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:
