안드로이드 getprop 구문 분석

Question

나는 안드로이드의 getprop 명령을 구문 분석하려고합니다. 여기 제가 사용하고있는 코드가 있습니다.

public class PropManager { 
    public String propReader() { 
     InputStream inputstream = null; 
     try { 
      inputstream = Runtime.getRuntime().exec("/system/bin/getprop") 
        .getInputStream(); 
     } catch (IOException e) { 
      e.printStackTrace(); 
     } 
     String propval = ""; 
     try { 

      propval = new Scanner(inputstream).useDelimiter("\\A").next(); 
      System.out.println(propval); 

     } catch (NoSuchElementException e) { 
      e.printStackTrace(); 
     } 
     return propval; 
    } 

    public String DeviceProp(String propval) { 
     String deviceprop = "none"; 
     try { 
      Scanner scanner = new Scanner(propval).useDelimiter("\\n"); 
      scanner.findWithinHorizon(
        Pattern.compile("\\[ro.product.model\\].*\\[([^\\0]+)\\]"), 
        0); 
      mbvsprop = scanner.match().group(1); 
     } catch (Exception e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     } 
     return deviceprop; 
    } 

} 

내가 오류를 받고 있어요 그러나, 여기에 스택 트레이스의 :

Answer 1

그것을 알고 열심히 당신을 아주 출력 코드와 과다를 읽고에서 불과 달성하기 위해 노력하고 있지만하는지 그걸 찔러 버릴거야.

이 무엇을 의미하는지 알 수는 없지만 점으로 대체하고 물음표를 사용하여 욕심이 없도록 만들면 다음 줄이 대체됩니다. 출력의 과다에 [SDK] : 코드, 나는 [ro.product.model]에서`sdk`을 분석하기 위해 노력하고있어

   Pattern.compile("\\[ro.product.model\\].*\\[(.+?)\\]"),
