Android does not support OpenType (OTF), only TrueType (TTF), so your Molot.otf font probably will not work. I wrote both of those blog posts you link to in your opening sentence (the one is a pirated copy of the other), and they do not use Molot.otf.
(BTW, I somewhat repaired the formatting of that post — AndroidGuys keeps changing WordPress hosts, and so my older posts are terribly broken in terms of formatting).
EDIT: As stated in the comments, Android DOES now support OTF.
