Appium : Clear a field

Question

I have my login screen in app now. Each time the app is launched in screen the mobile number is pre filled with the older text.

I just want to know I have tried:

Answer 1

List x=driver.findElements(By.className("enter widget details")); //You can get widget details via android UIautomator
driver.findElementById("enter widget details").click(); //You can get widget details via android UIautomator
x.get(index).clear();
x.get(index).clear();

Please note this worked for me but you may have to maneuver your code as per your requirements, thanks.
