what's wrong with hardcoded string in android xml file?

Question

I love to put simple text directly on the xml file without declaring a string first. It is easier, more simple and less messy. However, it always has a warning badge whenever I do so.

What if I have a dozens of hardcoded string in my xml file without concerning the warning? Will I get into a trouble?

thanks in advance.

When you use hard coded strings in both you java code and xml file your application directly writes these strings on RAM. But when you declare them as string resources it will not be written on RAM when application launches but they are written on RAM when application needs to use them. You can declare one billion strings in resources and you can still have a light weight RAM friendly Android application.
