아래 Runable을 Thread로 변경할려고하는데 이런 에러가 나네요
W/System.err( 7003): java.lang.IllegalThreadStateException: Thread already started.
W/System.err( 7003): at java.lang.Thread.start(Thread.java:1227)
....
기능은 간단합니다. 10밀리초마다 초를 찍는건데 Thread로 구성이 잘안되네요.
Stop,Start한 StopWatch를 구성하는것거등요

Thread는 start는 한번될 것이고 run메소드 수행 후 종료되지 않나요? new BackThread하시면..
