I have below configurations :

Javaclient : java-client-5.0.2

Selenium : 3.0.1

Java : 144

Appium v1.4.16

This is my code :

package com.metatag.poc;

import io.appium.java_client.MobileElement;
import io.appium.java_client.android.AndroidDriver;
import io.appium.java_client.android.AndroidDriver;
import java.io.File;
import java.net.MalformedURLException;
import java.net.URL;
import java.util.List;
import java.util.concurrent.TimeUnit;
import org.openqa.selenium.remote.CapabilityType;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.apache.bcel.generic.Select;
import org.openqa.selenium.By;
import org.openqa.selenium.SessionNotCreatedException;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebDriverException;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.By;

public class DesignLayout {

    //private static AndroidDriver driver;
    static AndroidDriver<MobileElement> driver;
    static WebElement ele;
    public static void main(String[] args) throws MalformedURLException, InterruptedException, WebDriverException {

        File classpathRoot = new File(System.getProperty("user.dir"));
        File appDir = new File(classpathRoot, "/Apps/");
        File app = new File(appDir, "MetaTag_V0.0.13_preview.apk");

        DesiredCapabilities capabilities = new DesiredCapabilities();
        capabilities.setCapability(CapabilityType.BROWSER_NAME, "");
//set capabilities          
        capabilities.setCapability("deviceName", "3G7");
        capabilities.setCapability("platformVersion", "4.4.1");
        capabilities.setCapability("platformName", "Android");
        capabilities.setCapability("app", app.getAbsolutePath());
        capabilities.setCapability("appPackage", "com.markspryor.markingmachine");
        capabilities.setCapability("appActivity", "in.opencombine.instrument.ui.HomeActivity");
        driver = new AndroidDriver<MobileElement>(new URL(""), capabilities);



If I run, Application gets install on real device and it shows following error :

  • Shot in the dark. What if you just do driver = new AndroidDriver(new URL(""), capabilities); without casting to MobileElement?

I was using following combination:

Appium : 1.6.5
Selenium : selenium-java-3.3.1
Appium Java Client : java-client-5.0.3

I downgraded the Appium client to:

Appium Java Client : java-client-5.0.0-BETA6

and the problem was solved.

I am not aware how/where to raise the issue of the version incompatibility issue.

  • looks like Appium has an issue with their latest version in converting some of the components to webdriver. I guess you can report it on their github or main site...doesn't look like you have the specifics with their code, but someone will hopefully know.

I found the solution, but can't explain how it works. But it works for me as a miracle.

Just add the below line, and magic happens. I don't have any idea how that makes it work:

capability.setCapability(MobileCapabilityType.NEW_COMMAND_TIMEOUT, "60");

It's issue with Version compatibility.

When i have upgraded Appium Server, It worked for me. Please try upgrading your Appium Server.

I am the author of the below video in which i explained how i reolved.


Please let me know if you have resolved in any other ways.
