안드로이드 활성화 문제

Question

<카운터가 다되면 잠금화면으로 가는 액티비티 2개로 이루어진 소스인데요

 카운트를 실행하고 홈키를 눌러서 다른 작업을 하다가 시간이 다되면 액티비티2(잠금화면)으로 가는데요

전화올떄처럼 프로그램이 어떤작업을 하고 있어도 액티비티2(잠금화면)으로 바뀌는거요>

부탁드립니다.

 

이게 카운터 소스구요

 

여기서 시간설정을해서 1시간 설정 하면 1시간이 줄어듭니다. 0이 되면 다음 액티비티로 넘어가는데요

        time = value*60000+ value2*1000;
        final MyCounter timer = new MyCounter(time,1000);
        timer.start();
