Favourite content is not shown correctly on webview

Question

I\'m developing a language dictionary app. I save the favourite word into Preference. The Favourite content in the XML file looks like the following:

Answer 1

I think the problem comes from this line

            mWordFavourite = new ArrayList(Arrays.asList(strFavourite.split(",")));

where you create a new ArrayList object every time but you should append to it? & get the last one otherwise you should put it in one variable

If you are checking if its size() >0

But each time you create a new object not appending to it

Maybe I am wrong!
