나는 스피커에 마이크에서 얻은 오디오 샘플을 통과하는 것을 시도하고는

를 사용하여, 내가 사용하고있는 코드입니다 마이크가 스피커로 전달되고 리턴 버튼을 누를 때 실이 멈추는 것처럼 보이므로 앱이 종료 될 때 통과가 중지됩니다. 그러나 앱을 다시 실행하면 통과가 발생하지 않습니다.
newThread = new MyThread(true);
newThread.start();
않는다 (즉,에서 onCreate()가 호출된다), 또는 어떤 이유로 이전 스레드의 상태를 기억 하는가? 이 앱을 완전히 재설정하면 완전히 새로운 앱이 실행될 때마다 시작될 수 있습니다.

그 다음 일시 중지하고 다시 시작하려면 어떻게해야합니까? – user13267
