Cannot instantiate the type AppiumDriver

Question

I have added following jars in my projects build path:

1. java-client-2.0.0 from http://appium.io/downloads.html >> Appium Client libraries >> Java
2. selenium-java-2.43.1
3. selenium-java-2.43.1-srcs

4. selenium-server-standalone-2.43.1
   and here's my code:

   public class SampleApp{
   
   WebDriver dr;
   
   @Test
   public void testApp() throws MalformedURLException, InterruptedException {
       String apkpath = "D:\\apkdump\\sampleapp.apk";
       File app = new File (apkpath);
       DesiredCapabilities capabilities= new DesiredCapabilities();
       capabilities.setCapability(CapabilityType.BROWSER_NAME,"");
       capabilities.setCapability("deviceName","TestADB18");
       capabilities.setCapability("platformName","Android");
       capabilities.setCapability("app",app.getAbsolutePath());
       capabilities.setCapability("appPackage", "com.test");
       capabilities.setCapability("appActivity", "com.sampleapp.Main");
       dr = new AppiumDriver(new URL("http://127.0.0.1:4723/wd/hub"),capabilities);
       dr.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);
   
   }
   
   
   }
   

   I am getting red line below new AppiumDriver which says that Cannot instantiate the type AppiumDriver. Now if remove all selenium jars the error disappears but then I can't resolve errors with webdriver.

   What is the conflict between jars?

   I saw similar question here but that could run the code and was getting Null pointer exception but in my case I cant even run it, it is giving run on saving the code. Secondly the answer has been posted without using AppiumDriver

Answer 1

You don't need to downgrade or anything. There is a design change in the Java Client version 2.0.0 as they mention on their site:

AppiumDriver is now an abstract class, use IOSDriver and AndroidDriver which both extend it.

So, just change your driver line to be:

dr = new AndroidDriver(new URL("http://127.0.0.1:4723/wd/hub"),capabilities);

Hope that helps...

Answer 2

This error can be fixed by downgrading the Appium Client(see step 1 in my question) from latest to java-client-1.5.0. You can keep rest of the jars to latest.

Downgraded version of Appium Client can be downloaded from here http://mvnrepository.com/artifact/io.appium/java-client/1.5.0

Answer 3

WebDriver driver = new AndroidDriver(new URL("http://127.0.0.1:4723/wd/hub"),getDesiredCapabilities("192.21.168.56:5555"));

use this. and import:

import io.appium.java_client.AppiumDriver;
import io.appium.java_client.android.AndroidDriver;
