Of course, they wouldn't run anyway because Android phones don't (AFAICT) have X. And even if you could you wouldn't want to do that because they wouldn't integrate with the Android UI and the result would be utterly horrible.

*Any* application that has a UI will have to have a UI written, and designed for, Android. And that's almost certainly going to mean Java, because that's what it's written in.

(It may be possible to wrap up all the JNI needed to call into the Android UI in, say, a set of C++ classes so that you can write a C++ app that used it; but it would be a repulsive amount of work and would probably be extremely brittle... and even then you wouldn't be able to subclass components, so you'd have to write Java code to receive callbacks. And, frankly, I don't see the benefit; you'll have to rewrite your UI to fit the Android framework anyway, so you might as well do it in the preferred language and save everyone a lot of time.)
