I was having the same problem. My font was not working in android either but I needed it to work. Using a font editor, I copied the characters from my font into the font that comes with the FontSampler example from Android-src-2_1. It worked perfectly.
While I will admit that my method was questionable from an intellectual property point of view, I didn't actually wind up using the original font, as all of the characters were replaced and all references to the old font where replaced as well. I had tried 'looking' at the way the two fonts were defined but making all the font variables match didn't work either. So in the ned, I used a skeleton of the original font as a template for the new font.
