Question

Android 카메라에서 원시 비디오 데이터를 캡처하려고합니다. Timer + TimerTask 패턴을 사용하고 있습니다.

long lastT = System.currentTimeMillis(); 
long curT = System.currentTimeMillis(); 
    timertask = new TimerTask() { 
       @Override 
       public void run() { 


        curT = System.currentTimeMillis(); 
        Log.d(TAG_VIDEO,">>\t" + (curT - lastT) + "\t::\t");// + data.length); 
        lastT = curT; 
} 
}; 
timer.scheduleAtFixedRate(timertask, 0L, 1000L/15L); 

그러나 LogCat은 3-170ms마다 내부 트레드를 시작한다고 말합니다. 왜? 그것을 고치는 방법? 다른 메소드 (핸들러, 스레드)는 동일한 결과를 제공합니다. 로그 :
