I need to use Helvetica font in my application(Android application). I have following questions regarding the same:
1. Is helvetica.ttf free for use in commercial projects?
2. What are the legal issues that one must consider when using fonts in their applications?
Any specific reason for this font?
As a rule of the thumb, it is always a good idea to go with the set system preferences, because the user is used to those preferences. Also, some people might have problems with a particular font. I personally find the "old document" style fonts very difficult to read though they look good aesthetically.
