I am trying to run my first test through Appium and getting the below error.

我只想使用Android默认浏览器，而不是Chrome。我不知道为什么Appium会尝试推出Chromedriver和Chrome浏览器。以下是我使用的代码。

import java.net.URL;                

import org.openqa.selenium.WebDriver;                
import org.openqa.selenium.remote.CapabilityType;                
import org.openqa.selenium.remote.DesiredCapabilities;                
import org.openqa.selenium.remote.RemoteWebDriver;                
import org.testng.annotations.AfterMethod;                
import org.testng.annotations.BeforeMethod;                
import org.testng.annotations.Test;                

public class Appium {                

    public WebDriver driver;            

    @BeforeMethod            
    public void beforeMethod() throws Exception {            
        // set up appium        
        DesiredCapabilities capabilities = new DesiredCapabilities();        
        capabilities.setCapability(CapabilityType.BROWSER_NAME, "Browser");        
        capabilities.setCapability("platformName", "Android");        
        capabilities.setCapability("deviceName", "Android Emulator");        
        capabilities.setCapability("platformVersion", "4.4.2");        
        WebDriver driver = new RemoteWebDriver(new URL(        
                http://****:4723/wd/hub), capabilities);
        driver.get("http://www.yahoo.com");        
    }            

    @Test            
    public void f() {            

    }            

    @AfterMethod            
    public void afterMethod() {            
        driver.quit();        
    }            

}

推荐答案

将旧的Chrome驱动程序替换为appium位置的新chrome驱动程序，它对我有用。

Replace old chrome driver to new chrome driver in appium location, it worked for me.

Appium位置应该是这样的：

The Appium location should be something like:

C:\Program Files (x86)\Appium\node_modules\appium\node_modules\appium-chromedriver\chromedriver\win\

Appium版本：1.4.16.1

Appium version : 1.4.16.1
