Android thread in service issue
<p>I am having a remote service running in which i am spawning a new thread to keep polling for incoming messages via socket and then at certain intervals i want to stop the socket and restart later...stopping is working fine (stopUARTConnection()) but re starting(startUARTConnection) is not causing the while loop again.. Can someone tell me whats wrong ?</p>
