Exception in thread “main” org.openqa.selenium.WebDriverException

I'm trying to test my application in eclipse IDE using java throwing this error. I started appium server also. gave matching port numbers too. this is my log trace. help me out.Thanks in advance

This is the code I used for testing my android app using appium:

public class MilonowFirstTest { static AppiumDriver<WebElement> driver; // @BeforeClass public static void main(String[] args) throws MalformedURLException //public void Setup() throws MalformedURLException { DesiredCapabilities cap = new DesiredCapabilities(); //cap.setCapability(AndroidMobileCapabilityType.De, value); cap.setCapability(MobileCapabilityType.DEVICE_NAME, "Android emulator"); //cap.setCapability(MobileCapabilityType.APP_PACKAGE, value); cap.setCapability(AndroidMobileCapabilityType.APP_PACKAGE, "com.test.myapp"); //cap.setCapability(MobileCapabilityType.APP, ""); cap.setCapability("avd", "Honor 7X API 27"); cap.setCapability(MobileCapabilityType.PLATFORM_NAME, "Android"); cap.setCapability(MobileCapabilityType.PLATFORM_VERSION, "23"); cap.setCapability(MobileCapabilityType.AUTOMATION_NAME, "Appium"); driver = new AndroidDriver<WebElement>(new URL(""), cap); Assert.assertNotNull(driver.getContext()); } // @Test() // public void SimpleTest() // { // Assert.assertNotNull(driver.getContext()); // } }

Error log:

Close the appium server and start it again, this should work. The permanent solution for this problem is:

    <li>Start Appium app</li> <li>Go to advance setting</li> <li>enter server address and server port that you want. I am using as server address and 4723 as server port</li> <li>Select or check session Override</li> </ul>

    If you like you can save this configuration as preset for using next time. Also include following desire capabilities in your app

    AppiumDriver<MobileElement> driver; DesiredCapabilities caps = new DesiredCapabilities(); caps.setCapability("deviceName", "Android phone"); caps.setCapability("udid", "your device uuid"); caps.setCapability("platformName", "Android"); caps.setCapability("platformVersion", "your device version"); caps.setCapability("appPackage", "name of app package"); caps.setCapability("appActivity", "name of app activity"); driver=new AndroidDriver<MobileElement>(new URL( ""), caps);

    <strong>How to find device uuid?</strong>

      <li>Enable usb debugging mode in your android device and connect to your laptop</li> <li>Open command prompt and type adb devices</li> </ul>

      It will show the list of connected devices to your laptop. Below List of devices attached you can find your device uuid

      <strong>How to find appPackage and appActivity</strong>

      click here: How to find appPackage and appActivity?


      Try by putting in desired capabilities parameter "APP",

      cap.setCapability(MobileCapabilityType.APP, "path_to_your_app");

      or as You started with a matched in-pair caps, if application is already installed on your device:

      cap.setCapability("appActivity", "com.test.myapp.ui.activities.MainActivity"); cap.setCapability("appPackage", "com.test.myapp");

      and You can check Your activity and package name with this command, by opening application on Your phone and going to console and run this:

      adb shell dumpsys window windows | grep -E 'mCurrentFocus|mFocusedApp'

      this will return something like this:

      mCurrentFocus=Window{5f6bfe8 u0 d0 abc.com.test.android/com.test.abc.ui.home.HomeActivity} mFocusedApp=AppWindowToken{123d4faf token=Token{asd2342 ActivityRecord{323tgee3 u0 abc.com.test.android/com.test.abc.ui.home.HomeActivity t1732}}}

      where as follows:

      Window{5f6bfe8 u0 d0 abc.com.test.android/com.test.abc.ui.home.HomeActivity}

      activity: `


      ...and is a package


      but recommended to put all params in the mix APP, APP_PACKAGE, APP_ACTIVITY

      hope this helps,


      You are calling

      driver = new AndroidDriver<WebElement>(new URL(""), cap);

      Correct URL should be <strong>/wd/hub</strong>.
