두 번째 파일로 쓸 때의 ANR

내 장치의 외부 저장소에있는 파일에 오류를 기록하고 있습니다. 처음으로 파일에 쓸 때 아무런 문제가 없습니다. 그러나 두 번째로 ANR을 얻습니다. 여기두 번째 파일로 쓸 때의 ANR

PrintWriter writer; 
try { 
    writer = new PrintWriter(
      new FileWriter(LOG_FILE_DIR + LOG_FILE, true) 
     ); 

    while(e != null){ 
     e.printStackTrace(writer); 
     e = e.getCause(); 
    } 

    writer.println(); 
    writer.println("--------------------------------------------------"); 
    writer.flush(); 
    writer.close(); 
} catch (IOException ex) { 
    ex.printStackTrace(); 
}

/data/anr/traces.txt의 출력됩니다 : 여기에 코드입니다

, 당신의 코드에 문제가있는 것 같다,하지만 Throwable이 원인이 포함되어있는 경우, 메소드가 중첩 된 Throwable에 대한 재귀 적으로 호출됩니다, e.printStackTrace(writer); 이미 당신이 원하는 무엇을 것을 받아 해당 스택 트레이스를 인쇄주의하지 않습니다 while 루프가 불필요합니다.
