Well, since you wouldn't see those in FF, Opera or webkit either... I'd suspect there's something wrong with your embed method.
The use of multiple SRC declarations could be a contributing factor when you only have one target. There's a reason I like the "fontsprint syntax" for handling that. It's pretty much bulletproof everywhere.
Which for your situation would go thus:
If you don't have the formats for other browsers, font squirrel does a great job on conversions and even gives you sample code to work from.
Pretty much your entire second line of "src" is probably what's messing things up... given what a rare/uncommon font droidsans is, I'd not even waste time TRYING to check for a local copy.
Oh, and be sure it's the VERY FIRST THING in your CSS, or it may get ignored in legacy browsers -- needs to go before ALL other code... including @charset -- not that there is ANY reason to use @charset since valid CSS is restricted to ASCII7... meaning the character encoding should be a total non-issue!
