I am working on Android projects. I need to use a background thread that should use handlers. My doubt is when we are using a new thread , what is the need to have handler associated with it . I am very much confused of using Handlers in my program. I did n't find any good tutorials or sample programs that deal with Hanlders.Can any one post me a sample program on Android Handlers? I will be waiting for reply.

thanks in Advance,
