Unable to initiate android driver with the right capabilities in appium project

Question

I am new to mobile automation and trying to setup appium with eclipse and also successfully connected a real device. I have installed all the required software and packages. I am able to find my devices under adb device list.

I have created a simple project in eclipse and declared all the right parameters in the DesiredCapabilities method. I have also included the appPackage and appActivity but my error shows

The desired capabilities must include either 'appPackage' or 'browserName'

public class NewTest {
    AndroidDriver driver;
    AppiumDriverLocalService service;

    @Test
    public void f() {         
          driver.findElement(By.id("com.google.android.youtube:id/menu_search")).click();
          driver.findElement(By.xpath("com.google.android.youtube:id/search_edit_text")).sendKeys("nota");
                      }

   @BeforeTest
   public void beforeTest() {
          service = AppiumDriverLocalService.buildDefaultService();
          service.start();
          DesiredCapabilities capabilities = new DesiredCapabilities();
          capabilities.setCapability("deviceName", "S51C1LV1C0056422"); 
          capabilities.setCapability("browserName", "Android");
          capabilities.setCapability("platformVersion", "4.4.2");
          capabilities.setCapability("platformName", "Android");
          capabilities.setCapability("appPackage", "com.google.android.youtube");
          capabilities.setCapability("appActivity", "com.google.android.apps.youtube.app.WatchWhileActivity");
          try {
            driver = new AndroidDriver(new URL("http://0.0.0.0:4723/wd/hub"), capabilities);
        } catch (MalformedURLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
          driver.manage().timeouts().implicitlyWait(15, TimeUnit.SECONDS);
      }

   @AfterTest
   public void afterTest() {
          service = AppiumDriverLocalService.buildDefaultService();
          service.stop();
          driver.quit();
      }        
    }

Below is the console output.

Answer 1

You must define AppiumDriver instead of AndroidDriver.

public class NewTest {
    AppiumDriver<WebElement> driver;
    //...
}

Include appPackage, appActivity, platformName, deviceName in Desired capabilities.

DesiredCapabilities caps = new DesiredCapabilities();
caps.setCapability("deviceName", "Android phone");   
caps.setCapability("platformName", "Android");  
caps.setCapability("appPackage", "Your app Package");
caps.setCapability("appActivity", "app activity name");

Don't include browserName if you are not opening your app in web browser.

Initialize your driver like following:

driver = new AndroidDriver<WebElement>(new URL(
                    "http://0.0.0.0:4723/wd/hub"), caps);

Answer 2

If you pass browserName and appPackage both capabilities then that means its a contradiction , as appium will not be able to understand that it has to launch browser (based on browerName cap) or app(based on appPackage cap)

Remove browser name capability

  capabilities.setCapability("browserName", "Android");

Add this capability

  capabilities.setCapability("platformName", "Android");
