Question

我的代码如下（取自here）

public class MainActivity extends ActionBarActivity implements ROXIMITYEngineListener, BeaconConsumer {
    private final String TAG = "MainActivity";

    private BeaconManager beaconManager;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        beaconManager = BeaconManager.getInstanceForApplication(this.getApplicationContext());
        beaconManager.bind(this);
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        beaconManager.unbind(this);
    }

    @Override
    public void onBeaconServiceConnect() {
        Log.i(TAG, "onBeaconServiceConnect");

        beaconManager.setMonitorNotifier(new MonitorNotifier() {
            @Override
            public void didEnterRegion(Region region) {
                Log.i(TAG, "I just saw an beacon for the first time!");
                Toast.makeText(MainActivity.this, "I just saw an beacon for the first time!", Toast.LENGTH_LONG).show();
            }

            @Override
            public void didExitRegion(Region region) {
                Log.i(TAG, "I no longer see an beacon");
                Toast.makeText(MainActivity.this, "I no longer see an beacon", Toast.LENGTH_LONG).show();
            }

            @Override
            public void didDetermineStateForRegion(int state, Region region) {
                Log.i(TAG, "I have just switched from seeing/not seeing beacons: "+state);
                Toast.makeText(MainActivity.this, "I have just switched from seeing/not seeing beacons: "+state, Toast.LENGTH_LONG).show();
            }
        });

        beaconManager.setRangeNotifier(new RangeNotifier() {
            @Override
            public void didRangeBeaconsInRegion(Collection<Beacon> beacons, Region region) {
                if (beacons.size() > 0) {
                    Log.i(TAG, "The first beacon I see is about " + beacons.iterator().next().getDistance() + " meters away.");
                    Toast.makeText(MainActivity.this, "The first beacon I see is about " + beacons.iterator().next().getDistance() + " meters away.", Toast.LENGTH_LONG).show();
                }
            }
        });

        try {
            beaconManager.startMonitoringBeaconsInRegion(new Region("uniqueid1", null, null, null));
            beaconManager.startRangingBeaconsInRegion(new Region("uniqueid2", null, null, null));
        } catch (RemoteException e) {
            Log.e(TAG, "", e);
        }
    }
}

onBeaconServiceConnected确实被称为！但没有其他任何东西被称为/打印。没有错误抛出。
我错过了什么？

同一个人（Radius Networks）的这个app可以检测到我的灯塔，为什么我的应用程序不能这样做呢？

我的手机是运行Android 5.1的Nexus 5。我正在使用Android Beacon Library 2.1.4，而我正在使用Android Studio版本1.2.1.1 （我认为这不重要，但我的灯塔是Roximity Model X）

我也尝试过只进行监控，但它也没有。

有趣的是，当我看到没有过滤器的logcat时，我可以看到BtGatt正在进行扫描并检测到信标：

Answer 1

我的猜测是你正在尝试检测专有信标（例如iBeacon）。因为库是开源的，所以默认情况下它不会检测专有信标，因为这样做会要求我们发布专有的信标格式。这可能会导致法律问题。

修复很简单。您只需要在onCreate方法中添加一行代码，以设置专有信标类型所需的信标解析器。

Google搜索“getbeaconparsers”，您会看到要添加的代码行。

    private BeaconManager beaconManager;
    @Override
    protected void onCreate(Bundle savedInstanceState {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity);
        beaconManager = BeaconManager.getInstanceForApplication(this);
//layout of ibeacon        
beaconManager.getBeaconParsers().add(new BeaconParser().setBeaconLayout("m:2-3=0215,i:4-19,i:20-21,i:22-23,p:24-24"));
        ...
    }

Answer 3

您的监控和测距区域名称应相同。试试这个：

beaconManager.startMonitoringBeaconsInRegion(new Region("uniqueid1", null, null, null));
beaconManager.startRangingBeaconsInRegion(new Region("uniqueid1", null, null, null));

Altbeacon - 监控或测距都没有错误
