All the hardcoded sizes are now put in the dimens.xml.
Why
Some of the sizes are used more than once, and it is easy to have this in one place so that you don't have to change a lot of files when you want to change the size.
How
You can check in the code what is changed, and start the app to check that everything still looks right.
