如何解决在Android上运行appium驱动程序的问题

Question

试图使用appium为Android运行一个示例测试。appium的设置是用node.js后端完成的。

我在Appium邮件列表中搜索了以下错误。但是，我仍然无法用一个明确的答案来解决这个问题。这应该是安装方法上的一个简单问题。有人能在这里指出这个问题吗？

以下是设置代码：

    @Before
    public void setUp() throws Exception {
        File app = new File( "/home/karthi/android/codebase/Sample/bin/TestingActivity-debug.apk");
        DesiredCapabilities capabilities = new DesiredCapabilities();
        capabilities.setCapability(CapabilityType.BROWSER_NAME, "Browser");
        capabilities.setCapability(CapabilityType.PLATFORM, "Android");
        capabilities.setCapability(CapabilityType.VERSION, "4.1.2");
        capabilities.setCapability("automationName","Appium");
        capabilities.setCapability("platformName","Android");
        capabilities.setCapability("platformVersion", "4.1.2");
        capabilities.setCapability("autoLaunch", true);
        capabilities.setCapability("deviceName", "Android Emulator");
        capabilities.setCapability("device-orientation", "portrait"); 
        capabilities.setCapability("app", app.getAbsolutePath());
        capabilities.setCapability("app-package", "com.hola.sampleapp");
        capabilities.setCapability("app-activity", ".activities.TestingActivity");
        driver = new AppiumDriver(new URL("http://localhost:4723/wd/hub"), capabilities);
    }

当尝试在Ubuntu14.04中的Eclipse中运行此程序时，我得到了以下错误

Answer 1

可能的原因：

您将本地主机作为IP，确保它与appium开始包含端口的IP匹配。

您正在android版本低于4.2的模拟器上运行测试。

Answer 2

提供IP地址和端口，与appium设置ip和端口相同。

将您的版本更改为最新版本或4.1.2以上，并删除

capabilities.setCapability(CapabilityType.BROWSER_NAME, "Browser");

Answer 3

我知道这是个很老的问题。但是这里是使用Appium的的一个示例工作模板，Appium是在Java中使用的，并在代码中启动Appium服务器。
