404!  Please don't think it sounds wired by the page title.

This is where i would like to bring in my experience of solving various errors i have come across with automation.I always believe learning from your errors is more important rather than learning some thing new or which does not exists.

That's the reason for this post.

UIElement cannot be cast to java.util.List
java.lang.ClassCastException: io.appium.java_client.ios.UIElement cannot be cast to java.util.List
I resolved this issue by creating a new function for List<webelement> 

The reason for the error was my  
List<WebElement> TapPinNo = <was calling the findelement(by.css(“”))
It should have called instead , findelements(by.css(“ “));
So i created a new function to call List<webelements> , instead of just webelement, all my
 findelement was calling another function within UILocator class in the framework.
If the elements are declared locally, then prefer to change it with in the code , like
"driver.findelement" to "driver.findelements"

Appium error: unknown error: operation is unsupported on Android
Solution :
That command is not supported on Android webviews. You cannot do it.
Scroll /swipe  is not happening by default in webviews when finding the element. 
Seems to work in iOS (Safari browser), but not in Android (Chrome).
Hence we need to switch the view to NATIVE_APP
Like -
   Dimension dimension = driver.context("NATIVE_APP").manage().window().getSize();
