使用AltBeacon

Question

我想使用AltBeacon库来检测来自Radius Networks的RadBeacon标记。为了理解这个库是如何工作的，我想使用AltBeacon的参考应用程序。

我在我的示例应用程序中实现了this code。在将AltBeacon库添加到项目中之后，我就可以运行项目了。

就像我之前提到的，我喜欢检测Radius Networks的IBeacons RadBeacon标签。我知道我需要使用BeaconParser。我的问题是RadBeacon标签的BeaconParser是什么样子的。Here是一个用于估计信标的IBeacon解析器。

当我调试这个项目并查看logcat内部时，我可以看到以下消息：

"Beacon detected: id1: "UUID of RadBeacon" id2= "Major of RadBeacon" id3:"Minor of RadBeacon"".
"looking for ranging region mathes for this beacon"
"got record"
"This is not a matching Beacon advertisment."

如何更改BeaconParser？这是我的源代码

public class FindRadBeaconActivity extends ActionBarActivity implements BeaconConsumer{
private BeaconManager beaconManager = BeaconManager.getInstanceForApplication(this);
protected static final String TAG = "RangingActivity";

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

    // check bluetooth
    verifyBluetooth();

    beaconManager.getBeaconParsers().add(new BeaconParser().
            setBeaconLayout("m:0-3=4c000215,i:4-19,i:20-21,i:22-23,p:24-24"));
    beaconManager.debug = true;
    beaconManager.bind(this);

}

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



@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.find_rad_beacon, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();
    if (id == R.id.action_settings) {
        return true;
    }
    return super.onOptionsItemSelected(item);
}

@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!");       
    }

    @Override
    public void didExitRegion(Region region) {
      Log.i(TAG, "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);      
    }
    });

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

private void verifyBluetooth() {

    try {
        if (!BeaconManager.getInstanceForApplication(this).checkAvailability()) {
            final AlertDialog.Builder builder = new AlertDialog.Builder(this);
            builder.setTitle("Bluetooth not enabled");          
            builder.setMessage("Please enable bluetooth in settings and restart this application.");
            builder.setPositiveButton(android.R.string.ok, null);
            builder.setOnDismissListener(new DialogInterface.OnDismissListener() {
                @Override
                public void onDismiss(DialogInterface dialog) {
                    finish();
                    System.exit(0);                 
                }                   
            });
            builder.show();
        }           
    }
    catch (RuntimeException e) {
        final AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setTitle("Bluetooth LE not available");         
        builder.setMessage("Sorry, this device does not support Bluetooth LE.");
        builder.setPositiveButton(android.R.string.ok, null);
        builder.setOnDismissListener(new DialogInterface.OnDismissListener() {

            @Override
            public void onDismiss(DialogInterface dialog) {
                finish();
                System.exit(0);                 
            }

        });
        builder.show();

    }

}

}

如果您正在寻找RadBeacon布局，请使用以下布局

mBeaconManager
            .getBeaconParsers()
            .add(new BeaconParser()
                    .setBeaconLayout("m:2-3=0215,i:4-19,i:20-21,i:22-23,p:24-24,d:25-25"));
