Question

我无法检测到附近的信标，我正在关注来自here的代码，其中使用信标扫描应用程序我能够检测到信标，可能是什么问题。

import android.graphics.BitmapFactory;
import android.os.AsyncTask;
import android.os.Bundle;
import android.os.RemoteException;
import android.util.Log;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.EditText;

public class MainActivity extends Activity implements BeaconConsumer{

    private BeaconManager beaconManager;
    protected static final String TAG = "MonitoringActivity";
    EditText editText;// = (EditText)findViewById(R.id.reg_firstname);
    private String line;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        editText =  (EditText)findViewById(R.id.log);
        beaconManager = BeaconManager.getInstanceForApplication(this);

         beaconManager.bind(this);

    }

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

     @Override
        public void onBeaconServiceConnect() {
            beaconManager.setMonitorNotifier(new MonitorNotifier() {
            @Override
            public void didEnterRegion(Region region) {
                Log.i(TAG, "I just saw an beacon for the first time!");        
                editText.append("I just saw an beacon for the first time!");
            }

            @Override
            public void didExitRegion(Region region) {
                Log.i(TAG, "I no longer see an beacon");
                editText.append("I no longer see an beacon");
            }

            @Override
                public void didDetermineStateForRegion(int state, Region region) {
                Log.i(TAG, "I have just switched from seeing/not seeing beacons: "+state);   
                editText.append("I have just switched from seeing/not seeing beacons: "+state);
                }
            });

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



}

修改

根据以下答案，我在onCreate()

中添加了以下代码段

        beaconManager.getBeaconParsers().clear();
        beaconManager.getBeaconParsers().add(new BeaconParser().setBeaconLayout("m:2-3=beac,i:4-19,i:20-21,i:22-23,p:24-24,d:25-25"));//ALTBEACON_LAYOUT
        beaconManager.getBeaconParsers().add(new BeaconParser().setBeaconLayout("s:0-1=feaa,m:2-2=00,p:3-3:-41,i:4-13,i:14-19"));//EDDYSTONE_UID_LAYOUT
        beaconManager.getBeaconParsers().add(new BeaconParser().setBeaconLayout("m:2-3=0215,i:4-19,i:20-21,i:22-23,p:24-24,d:25-25"));//Kontakt beacon
        beaconManager.setForegroundScanPeriod(1000l);
        beaconManager.setForegroundBetweenScanPeriod(10000l);

但它只显示了一个信标设备。但是在这里使用应用程序https://play.google.com/store/apps/details?id=com.radiusnetworks.locate&hl=en我能够检测到两个信标。

默认情况下，Android Beacon Library只会检测AltBeacon传输。如果您希望它检测其他信标格式，如Eddystone或iBeacon，则必须为该信标类型提供BeaconParser格式。您可以通过Google搜索轻松找到信标类型的不同BeaconParser表达式。

iBeacon没有检测到附近的信标设备
