android의 ibeacon 스캔 결과가 스마트 폰에 표시되지 않음

Question

Android 스마트 폰을 사용하여 ibeacon을 감지하려고합니다. 나에게 안드로이드 라이브러리를 제공 한 회사에서 ibeacon 장치를 구입했다. (이 라이브러리는 내가 사용한 코드와 같은 AltBeacon의 안드로이드 비컨 라이브러리와 매우 흡사하다.) 나는이 장치를 감지 볼 수있는 로그 캣에서 전화 응용 프로그램을 실행하면

public class IBeaconListAdapter extends BaseAdapter { 

private Activity activity; 
private List<IBeacon> beacons; 
private static LayoutInflater inflater = null; 

public IBeaconListAdapter(Activity _activity, List<IBeacon> _beacons) { 
    this.activity = _activity; 
    this.beacons = _beacons; 
    inflater = (LayoutInflater)activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
} 

@Override 
public int getCount() { 
    return beacons.size(); 
} 

@Override 
public Object getItem(int position) { 
    return beacons.get(position); 
} 

@Override 
public long getItemId(int position) { 
    /*IBeacon beacon = beacons.get(position); 
    if (beacon != null) { 
     return beacon.hashCode(); 
    }*/ 
    return position; 
} 

@Override 
public View getView(int position, View convertView, ViewGroup parent) { 

    View view = convertView; 

    if (convertView == null) { 
     view = inflater.inflate(R.layout.beacon_list_row, null); 
    } 

    TextView majorTextView = (TextView)view.findViewById(R.id.majorValue); 
    TextView minorTextView = (TextView)view.findViewById(R.id.minorValue); 
    TextView rssiTextView = (TextView)view.findViewById(R.id.rssiValue); 
    TextView accuracyTextView = (TextView)view.findViewById(R.id.accuracyValue); 

    IBeacon beacon = beacons.get(position); 

    if (beacon != null) { 
     DecimalFormat df = new DecimalFormat("#.0"); 
     majorTextView.setText(beacon.getMajor()); 
     minorTextView.setText(beacon.getMinor()); 
     rssiTextView.setText(beacon.getRssi() + " dBm"); 
     accuracyTextView.setText(df.format(beacon.getAccuracy()) + " m"); 
    } 

    return view; 
} 

}

입니다 전화에서 나는 아무것도 볼 수없는 빈 페이지! LogCat에서 일단 onIBeaconServiceConnect가 호출되면 app이 startMonitoringBeaconsInRegion으로 점프하고 didRangeBeaconsInRegion 및 코드를 포함하는 didEnterRegion 메서드를 호출하지 않는다는 것을 알았습니다. 내 질문과 유사한 질문에 대한 다른 답변을 찾을 수 없으며 실제로 내 실수가 어디인지 알 수 없습니다.

Answer 1

몇 가지 생각 :

1. 이 비콘 정말 전송하고 당신이 그들이 생각하는 식별자를 가지고 있는지 확인하십시오. Locate과 같은 기성품 앱을 다운로드하고 확인하십시오.

2. 귀하의 코드는 UHID가 acfd065e-c3c0-11e3-9bbe-1a514932ac01 인 비컨을 찾고있는 지역을 설정합니다. 이게 정확히 맞는 거니? 영역 정의를 Region("BlueUp", null, null, null);으로 바꾸어 식별자에 관계없이 영역을 감지하도록하십시오.

3. 중요한 개발을 계획중인 경우 Android Beacon Library 2.0으로 업그레이드하는 것이 좋습니다. 라이브러리가 기반으로하는 오래된 0.x 라이브러리 버전은 더 이상 지원되거나 유지 관리되지 않으므로 이와 같은 문제가 발생할 때 도움을 얻는 것이 더 어려워집니다.

이들은 LogCat의 중요한 라인입니다.
