Proper way to handle Android Studio's NullPointerException lint warning

Question

I\'m new to android/java programming and am confused how to properly deal with this warning.

Method invocation \'\' may produce \'Java.lang.NullPointe

Answer 1

I like the answer to this link.

Warning is not an Error. And the warning which you are talking about says "it may produce", don't say 'it must produce'. So choice is yours. Either add null check or not

So, If you are sure that findViewById in your code will never be cause of NPE, then don't add the null check.
