codeing

Nothing is wrong with your code as such, it would work fine in any java program however for the challenge you need to name the variable favouriteColor (not myfavouriteColor).

If you name the variable incorrectly it wont pass the check criteria.

By default convention in Java thus Android when naming variables what we use the camel casing i.e. the first letter of a word is in lowercase and the preceding first letters of next words are in uppercase

(Note -- again camel casing is not compulsory but is a general convention )

for e.g. helloWorld = hello (first word's first letter in lowercase) + World (next word's first letter in uppercase)

Similarly

myFavouriteColor

And as I checked and suggested by Daniel its favouriteColor and not myfavouriteColor ... remove the my and it should be good.

thank you guys ..
