Appium _org.openqa.selenium.SessionNotCreatedException

Question

I am running appium script , for android app.

But it is not at all running.

I have added all the dependency in my maven project required to run the test.

Adding all of my code below.

Please check and help me.

Launch Class

      package TestCases.Project_Entry;

    import java.io.File;
    import java.net.MalformedURLException;
    import java.net.URL;
    import java.util.concurrent.TimeUnit;

    import org.openqa.selenium.remote.DesiredCapabilities;
    import org.testng.annotations.BeforeSuite;
    import org.testng.annotations.BeforeTest;
    import org.testng.annotations.Test;

    import io.appium.java_client.android.AndroidDriver;
    import io.appium.java_client.android.AndroidElement;
    import io.appium.java_client.remote.MobileCapabilityType;

    public class launch {

        AndroidDriver<AndroidElement> driver;

        public AndroidDriver<AndroidElement> capabilities() throws MalformedURLException {

            // TODO Auto-generated method stub
            File appDir = new File("src");
            File app = new File(appDir, "app-staging-debug.apk");
            DesiredCapabilities capabilities = new DesiredCapabilities();
            capabilities.setCapability(MobileCapabilityType.APP, app.getAbsolutePath());

            capabilities.setCapability(MobileCapabilityType.DEVICE_NAME, "Palak");
            capabilities.setCapability(MobileCapabilityType.AUTOMATION_NAME, "UiAutomator2");
            capabilities.setCapability(MobileCapabilityType.NEW_COMMAND_TIMEOUT, "25");
            capabilities.setCapability("autoGrantPermissions", true);

            capabilities.setCapability("--session-override", true);
            driver = new AndroidDriver<AndroidElement>(new URL("http://127.0.0.1:4723/wd/hub"), capabilities);
            driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);

            return driver;
        }

    }

1. I have already tried , re-starting eclipse.
2. Adding automation name as ui automator 2

    package TestCases.Project_Entry;

    import java.io.IOException;
    import java.net.MalformedURLException;

    import org.openqa.selenium.remote.RemoteWebDriver;
    import org.testng.annotations.*;

    import PageObject.loginObjects;
    import io.appium.java_client.android.AndroidDriver;
    import io.appium.java_client.android.AndroidElement;

        public class loginTestCases extends launch {
            AndroidDriver<AndroidElement> driver;

            @BeforeTest
        public void openapp() throws MalformedURLException {
            capabilities();
        }



        @Test
        public void log() {


            driver.findElementById("versionx.entryPoint:id/ed_verificationEmail").sendKeys("213214");

        }

    }

Answer 1

I think you need to add a capability.

capabilities.setCapability("appWaitActivity", "*");

Also re-check APK path

Answer 2

只是为了消除这种可能性，将您的应用程序放在桌面上并从那里添加路径，它将被硬编码，但这只是为了确保应用程序路径不是问题。
