    AppiumDriver<MobileElement> driver = null;

    @Test
    public void FirstCheck() throws MalformedURLException, InterruptedException
    {

        //Set the Desired Capabilities
        DesiredCapabilities caps = new DesiredCapabilities();
        caps.setCapability("deviceName", "My Phone");
        caps.setCapability("udid", "ZY223NZKZQ"); //Give Device ID of your mobile phone
        caps.setCapability("platformName", "Android");
        caps.setCapability("platformVersion", "7.0");
        caps.setCapability("appPackage", "com.android.vending");

  • @Anonygoose It worked for me. Downloaded Apache Commons Lang 3.10 and all errors vanished and further actions are performed smoothly. thanks a lot. – Antim Bhowal Apr 22 at 5:16

Looks like you're missing Apache Commons Lang. If you're using Maven, add it as a dependency, otherwise download it from the link below and put the jar on your classpath.
