I just restarted appium and it worked for me

[shahulprofile]

Run Appium. It will create new session, Find the port number. (always it will be like - address “127.0.0.1” --robot- port 4) Port number should match with the capability.

Example: If my port number is 4, then

	AndroidDriver driver = new AndroidDriver(new URL("http://127.0.0.1:4/wd/hub"),cap);

Thanks, Shameed.
