Question

我无法使用android信标库检测到ibeacon存在。这是我的代码

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);

在onBeaconServiceConnect方法中

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) {    }
    }

我还在AndroidManifest.xml中添加了此权限

<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"/>

在输出中

我用两部不同的手机尝试了这个代码，并没有对其中的任何一部分进行操作。此输出是当我尝试使用Samsung S6的代码时。使用三星s4我没有得到这个状态 - 确定/找不到...消息，我得到了这个

一些提示：

如果您的设备安装了Android 6+，则必须确保您已按照此处所述授予位置权限：http://developer.radiusnetworks.com/2015/09/29/is-your-beacon-app-ready-for-android-6.html
尝试使用此相同库的现成Locate app。如果该应用无法检测到信标，则信标发射器本身可能存在问题。
确保在设置中启用了位置。
确保在“设置”中启用了蓝牙。
