Automation test case is working for appium command line tool but not for desktop client

Question

PLEASE HELP ME!!!. I'm trying to automate an android app. I'm using JAVA. If i start the appium server from the command line and run the test case, it is working fine. But when i start the appium sever using Appium desktop client(Version - 1.13.0), i'm getting an error. Why does the test case keep failing when using Appium desktop client(Version - 1.13.0) whereas the same code works fine when run with the appium command line tool?

I'm using Appium(1.14.0) and Appium Desktop version(1.13.0) with Java 8 and along with the following jar files

• Selenium Remote Driver-3.14.0
• Java-client-7.0.0

• Apache commong language file - 3.7

   public static AndroidDriver<AndroidElement> InstallInvokeAPK() throws MalformedURLException { //Define the source folder File f1 = new File("src"); //Define the destination and name of the APK file File f2 = new File(f1, "New Driver app-excel-debug.apk"); //COnfiguration setting to work with the application DesiredCapabilities cap = new DesiredCapabilities();//Creating an object of Desiredcapabilities class cap.setCapability(MobileCapabilityType.PLATFORM_NAME, MobilePlatform.ANDROID);//Defining the platform cap.setCapability(MobileCapabilityType.DEVICE_NAME, "Moto G (5) Plus");//Defining the Mobile handset name cap.setCapability(MobileCapabilityType.UDID, "ZY223Z68JG"); cap.setCapability("automationName", "UiAutomator2"); cap.setCapability(MobileCapabilityType.NEW_COMMAND_TIMEOUT, 100);//Defining the maximum timeout period to execute command cap.setCapability("autoGrantPermissions", "true"); cap.setCapability(MobileCapabilityType.APP, f2.getAbsolutePath()); //Use the Android Driver to work with Android Platform Elements AndroidDriver<AndroidElement> driver = new AndroidDriver<AndroidElement>(new URL("http://127.0.0.1:4723/wd/hub"),cap); return driver; public class TestApp extends Example2{ public static void main(String[] args) throws InterruptedException, MalformedURLException { AndroidDriver<AndroidElement> driver = InstallInvokeAPK(); //AndroidDriver<AndroidElement> driver = PackageActivity("com.e9ine.android.driver", "com.e9ine.android.driver.module.AuthenticationModule.view.activity.SpalshScreenActivity"); driver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS); driver.findElement(By.xpath("//android.widget.EditText[@text='Username']")).sendKeys("abc@xyz.com"); driver.findElement(By.id("editText_password")).sendKeys("1234"); driver.navigate().back();

Answer 1

1. Remove your Selenium Remote Driver-3.14.0 dependency, Appium Java Client 7.0.0 includes selenium-java, selenium-support and selenium-api versions 3.141.59 as transitive dependencies . If you particularly need Selenium Remote Driver I would suggest to ramp it up to 3.141.59 to avoid any API inconsistencies.
2. Try resetting your ADB host by running adb kill-server command . Prior to launching your Appium test make sure to execute abd devices command and double check that your phone is in connected state
