No. Callbacks are not implemented.

Typically you would write a native method that is called from a separate 
thread from the primary application. The native method suspends itself 
and is woken up when a desired event happens (See sleep, suspend, resume 
methods in Native_API.txt - The NativeLibrary example uses sleep). The 
trick is that you cannot wake the thread from an ISR without risking 
deadlock. IO_Poll is typically used to resume native threads. The ISR 
signals your IO_Poll routine (IO_Poll routines, installing/removing are 
described in Native_API.txt) and your IO_Poll routine wakes up your 
thread. Your thread can then fill in an array or return a standard data 
type (this is done in the nativelibrary sleep example) to return back to 
Java.

The netcam reference 
(ftp://ftp.dalsemi.com/pub/tini/reference_designs/netcam/) is a more 
complex example. See camera.a51 for the native code and camera.java for 
the related Java code.
