I'm not sure why you can't just use a thread (no handler)?
If you do need a handler, you can just create a new runnable, and post
it to the handler with something like:
new Handler().post(new Runnable(){
public void run(){
image = new GLCamTest().extractimage(q);
}
});
(Obviously, the code above isn't perfect, but hopefully it helps);
