所有的信标不使用的Android库altBeacon所示 [英] All beacons are not shown in Android using altBeacon library
本文介绍了所有的信标不使用的Android库altBeacon所示的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我使用 AltBEacon的Android库以开发Android的 iBeacon显示应用设备。我在扫描但是，只有 2出4信标发现标（有时1/4）。我增加 mBeaconManager.setForegroundScanPeriod（5000升）; 来5秒，但仍然相同的结果。我不知道，如果 CustomAdapter 我用绑定细节观点是错误或问题是做移动设备（我用的Galaxy Note II - 4.4.2） ？ 任何人都可以找到我的错误？
另一个问题是，从设备的距离计算到信标返回不正确（当我约0.5米程返回betweem 3 -6M ）
我在做什么错了？任何帮助appriciated
的注：我已经检查UUID，主要，灯塔的未成年人任何错误。我已经增加了这些扫描time.None工作。的

解决方案
好吧，我终于解决了这个问题。我按照信标 MAC地址订购。因此，而不是：
公共无效initAll（收集和LT;烽火台＆GT; newBeacons）{
this.beacons.clear（）;
this.beacons.addAll（newBeacons）;
}
我所做的：
公共无效initAll（收集和LT;烽火台＆GT; newBeacons）{
this.beacons.clear（）;
this.beacons.addAll（newBeacons）;
//分类
Collections.sort（this.beacons，新的比较＆LT;＆警号GT;（）{
@覆盖
公众诠释比较（灯塔B1，B2灯塔）{
串MAC1 = b1.getBluetoothAddress（）;
串MAC2 = b2.getBluetoothAddress（）; 返回mac1.compareTo（MAC2）;
}
}）;
}
I am using AltBEacon Android library for developing an iBeacon app for Android Devices. I am scanning for beacons however only 2 out of 4 beacons are found(sometimes 1/4). I increasemBeaconManager.setForegroundScanPeriod(5000l); to 5sec but still same result. I am not sure if the CustomAdapter i use for binding details to view is wrong or the issue is do to the mobile device (I am using Galaxy Note II - 4.4.2)? Can anyone locate my mistake?
Another issue is that the distance calculation from device to the beacon is returning not correct (when i am approx 0.5m away it returns betweem 3-6m)
What i am doing wrong? Any help is appriciated
Note: I have checked UUID, Major, Minors of Beacon for any mistake. I have increased the scanning time.None of these worked.
Here is the Fragment that starts monitoring and ranging:
public class FragmentScanBeacons extends Fragment implements BeaconConsumer{
public static Region mRegion = new Region("Server", Identifier.parse("Here is my UUID"), null, null);
private BeaconManager mBeaconManager;
private BeaconBaseAdapter beaconBaseAdapter;
private ListView beaconsListLv;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mBeaconManager = BeaconManager.getInstanceForApplication(getActivity());
//BEACON PARSER
mBeaconManager.getBeaconParsers().add(new BeaconParser().setBeaconLayout("m:2-3=0215,i:4-19,i:20-21,i:22-23,p:24-24"));
// mBeaconManager.debug = true;
beaconBaseAdapter = new BeaconBaseAdapter(getActivity());
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_beacons, container, false);
//UI
beaconsListLv = (ListView) view.findViewById(R.id.beaconsListView);
//Set Adapter
beaconsListLv.setAdapter(beaconBaseAdapter);
//Check for bluetooth and Scan for Beacon
verifyBluetooth();
//Start Monitoring and Ranging
mBeaconManager.bind(this);
return view;
}
@Override
public void onResume() {
super.onResume();
if(mBeaconManager.isBound(this)){
mBeaconManager.setBackgroundMode(false);
}
}
@Override
public void onPause() {
super.onPause();
if(mBeaconManager.isBound(this)){
mBeaconManager.setBackgroundMode(true);
}
}
@Override
public void onDestroy() {
super.onDestroy();
mBeaconManager.unbind(this);
}
@Override
public void onBeaconServiceConnect() {
try {
//Scan lasts for SCAN_PERIOD time
mBeaconManager.setForegroundScanPeriod(1000l);
// mBeaconManager.setBackgroundScanPeriod(0l);
//Wait every SCAN_PERIOD_INBETWEEN time
mBeaconManager.setForegroundBetweenScanPeriod(0l);
//Update default time with the new one
mBeaconManager.updateScanPeriods();
}catch (RemoteException e){
e.printStackTrace();
}
//Set Monitoring
mBeaconManager.setMonitorNotifier(new MonitorNotifier() {
@Override
public void didEnterRegion(Region region) {
Log.d("TEST", "ENTERED beacon region");
//Start Raning as soon as you detect a beacon
try {
mBeaconManager.startRangingBeaconsInRegion(mRegion);
} catch (RemoteException e) {
e.printStackTrace();
}
}
@Override
public void didExitRegion(Region region) {
Log.d("TEST", "EXITED beacon region");
}
@Override
public void didDetermineStateForRegion(int state, Region region) {
Log.d("TEST", "SWITCHED from seeing/not seeing beacon to state " + state);
}
});
//Set Ranging
mBeaconManager.setRangeNotifier(new RangeNotifier() {
@Override
public void didRangeBeaconsInRegion(final Collection<Beacon> beacons, Region region) {
if (beacons != null && beacons.size() > 0) {
getActivity().runOnUiThread(new Runnable() {
@Override
public void run() {
beaconBaseAdapter.initAll(beacons);
}
});
}
}
});
try {
//Start Monitoring
mBeaconManager.startMonitoringBeaconsInRegion(mRegion);
} catch (RemoteException e) {
e.printStackTrace();
}
}
@Override
public Context getApplicationContext() {
return getActivity().getApplicationContext();
}
@Override
public void unbindService(ServiceConnection serviceConnection) {
getActivity().unbindService(serviceConnection);
}
@Override
public boolean bindService(Intent intent, ServiceConnection serviceConnection, int mode) {
return getActivity().bindService(intent, serviceConnection, mode);
}
}
and here is the custom adapter:
public class BeaconBaseAdapter extends BaseAdapter {
private Context myContext;
private LayoutInflater inflater;
public static ArrayList<Beacon> beacons;
public BeaconBaseAdapter(Context context) {
this.myContext = context;
this.inflater = LayoutInflater.from(context);
this.beacons = new ArrayList<Beacon>();
}
public void initAll(Collection<Beacon> newBeacons) {
this.beacons.clear();
this.beacons.addAll(newBeacons);
notifyDataSetChanged();
}
@Override
public int getCount() {
return beacons.size();
}
@Override
public Beacon getItem(int position) {
return beacons.get(position);
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
convertView = inflater.inflate(R.layout.beacon_list_row, null);
convertView.setTag(new ViewHolder(convertView));
}
bind(getItem(position), position, convertView);
return convertView;
}
private void bind(Beacon beacon, int position, View view) {
ViewHolder holder = (ViewHolder) view.getTag();
holder.manufacturerTextView.setText("Manufacturer: " + beacon.getManufacturer());
holder.idOneTextView.setText("UUID: " + beacon.getId1());
holder.idTwoTextView.setText("Major: " + beacon.getId2());
holder.idThreeTextView.setText("Minor: " + beacon.getId3());
holder.txPowerTextView.setText("TX-Power: " + beacon.getTxPower());
holder.rssiTextView.setText("RSSI: " + beacon.getRssi());
holder.distanceTextView.setText(String.format("DISTANCE: (%.2f m)", beacon.getDistance()));
holder.nameTextView.setText("Bluetooth Name: " + beacon.getBluetoothName());
holder.addressTextView.setText("Bluetooth Adrs: " + beacon.getBluetoothAddress());
}
static class ViewHolder {
final TextView nameTextView;
final TextView manufacturerTextView;
final TextView idOneTextView;
final TextView idTwoTextView;
final TextView idThreeTextView;
final TextView txPowerTextView;
final TextView rssiTextView;
final TextView distanceTextView;
final TextView addressTextView;
ViewHolder(View view) {
nameTextView = (TextView) view.findViewWithTag("name");
manufacturerTextView = (TextView) view.findViewWithTag("manufacturer");
idOneTextView = (TextView) view.findViewWithTag("id_one");
idTwoTextView = (TextView) view.findViewWithTag("id_two");
idThreeTextView = (TextView) view.findViewWithTag("id_three");
txPowerTextView = (TextView) view.findViewWithTag("tx_power");
rssiTextView = (TextView) view.findViewWithTag("rssi");
distanceTextView = (TextView) view.findViewWithTag("distance");
addressTextView = (TextView) view.findViewWithTag("address");
}
}
}
解决方案
Ok i finally solved it. I ordered according to the beacon Mac Address. So instead of:
public void initAll(Collection<Beacon> newBeacons) {
this.beacons.clear();
this.beacons.addAll(newBeacons);
}
i did:
public void initAll(Collection<Beacon> newBeacons) {
this.beacons.clear();
this.beacons.addAll(newBeacons);
//Sort
Collections.sort(this.beacons, new Comparator<Beacon>() {
@Override
public int compare(Beacon b1, Beacon b2) {
String mac1 = b1.getBluetoothAddress();
String mac2 = b2.getBluetoothAddress();
return mac1.compareTo(mac2);
}
});
}
