Android :: Typeface / Italic Does Not Work With Sans Serif

I've got 2 problems with the Typeface.create(...) method :
- the javadoc for this methods say : "Create a typeface object given a family name, and option style information. If null is passed for the name, then the default font will be chosen". However if I use for example : Typeface.create(null, Typeface.ITALIC), it does not compile, with the following error : "The method create(String, int) is ambiguous for the type Typeface". This is because there is 2 different methods : create(String, int) and create(Typeface, int). I guess there is a problem with the API here :(
- italic does not work with sans serif. For example if I use Typeface.create(Typeface.SANS_SERIF, Typeface.ITALIC), the text will not be in italic. Bold works fine. Serif works fine with both bold and italic.
