無法檢測與Android信標庫ibeacon

Question

我無法檢測與Android信標庫ibeacon存在。這是我的代碼

BeaconManager beaconManager = BeaconManager.getInstanceForApplication(this); 
     beaconManager = BeaconManager.getInstanceForApplication(this); 
     if (beaconManager != null && !beaconManager.isBound(this)) { 
      beaconManager.getBeaconParsers().add(new BeaconParser(). 
        setBeaconLayout("m:0-3=4c000215,i:4-19,i:20-21,i:22-23,p:24-24")); 
      beaconManager.bind(this); 

而在onBeaconServiceConnect方法

public void onBeaconServiceConnect() { 
     BeaconManager beaconManager = BeaconManager.getInstanceForApplication(this); 
     beaconManager.setRangeNotifier(new RangeNotifier() { 
      @Override 
      public void didRangeBeaconsInRegion(Collection<Beacon> beacons, Region region) { 
       for (Beacon beacon : beacons) { 
        Log.i("MainActivity", "I see a beacon that is about "+beacon.getDistance()+" meters away."); 
        System.out.print("Beacon seen"+ beacon.getId1()); 
       } 
      } 
     }); 

     try { 
      beaconManager.startRangingBeaconsInRegion(new Region("myRangingUniqueId", null, null, null)); 
     } catch (RemoteException e) { } 
    } 

我也在我的AndroidManifest.xml

<uses-sdk 
     android:minSdkVersion="18" 
     android:targetSdkVersion="18" /> 
    <uses-permission android:name="android.permission.INTERNET" /> 
    <uses-permission android:name="android.permission.BLUETOOTH"/> 
    <uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/> 

加入這個權限在輸出

我嘗試了代碼w ith兩個不同的電話，它不適用於任何人。這個輸出是當我用Samsung S6來測試代碼的時候。隨着三星S4我沒有得到這個狀態OK /不能找到......的消息，我只是這個

Answer 1

一些提示：

• 如果您的設備具有的Android 6 +，則必須確保您具有如下所述的授予的位置權限：http://developer.radiusnetworks.com/2015/09/29/is-your-beacon-app-ready-for-android-6.html

• 嘗試使用此相同庫的現成Locate app。如果該應用程序無法檢測到信標，則信標發射器本身可能存在問題。

• 確保在設置中打開位置。

• 確保設置中的藍牙已打開。
