I'm trying to run the below code where the Appium server should start and the app should be installed in the emulator and perform some actions and close the app. But while running the below code getting the TestNG error. Can you please help me to resolve this issue?

Code:

package stepDefinitionFile;

+import java.io.File;

public class AppLaunch {

    AndroidDriver driver= new AndroidDriver(setup(), Capabilities());

    @BeforeSuite

    public URL setup()

    {

        AppiumDriverLocalService service = AppiumDriverLocalService.buildService(new AppiumServiceBuilder()

                .usingDriverExecutable(new File("C:/Program Files/nodejs/node.exe"))

                .withAppiumJS(new File("C:\Users\username\AppData\Local\Programs\Appium\resources\app\node_modules\appium\build\lib\main.js"))

                .withIPAddress("0.0.0.0").usingPort(4723).withLogFile(new File("target/LogtoCheck+1.log")));

                service.start();

                URL URL = service.getUrl();

                return URL;

    }



    @BeforeClass

    public DesiredCapabilities Capabilities() {



        File fd=new File("src");

        File FDchild=new File(fd,"ApiDemos-debug.apk");



        DesiredCapabilities cap=new DesiredCapabilities();

        cap.setCapability(MobileCapabilityType.DEVICE_NAME, "Vinesh");

        cap.setCapability(MobileCapabilityType.APP, FDchild.getAbsolutePath());

         return Capabilities();

    }



    @Test

        public void testFirst() {

             System.out.println("test method is success");

             allowAppPermission();

        }

        @AfterTest

    public void End() {

    driver.quit();

    }

    public void allowAppPermission(){



        while (driver.findElements(MobileBy.xpath("//*[@class='android.widget.Button'][1]")).size()>0) 



        {  

            driver.findElement(MobileBy.xpath("//*[@class='android.widget.Button'][1]")).click();

        }

} 

}
