If you access the camera (or other local resource) from Java using the 
standard APIs, you don't need to care about binary compatibility - that's what 
the Dalvik VM does.

PhoneGap's backend on Android is written in Java, and it provides a bridge to 
get there from JavaScript.

I don't see it as quite ready for prime time - see my reply to Jason H.


Here's something new:

The May 2012 release of the Android NDK (ie: the one that's still warm from 
the oven) has just had MIPS support added, so it looks like you actually can 
support all of the architectures in one go - and in a single apk.

   http://developer.android.com/sdk/ndk/index.html

I shall have to go away and test it.

@Nicola: it may just be that your prayers have been answered. :-)
