我正在尝试在我的应用程序中实现信标检测，并且我正在使用 altBeacon 库，我已经采用了库站点中显示的示例，但 ti 似乎无法正常工作。这里是代码：
public class BeaconActivity extends BaseActivity implements BeaconConsumer,RangeNotifier {
private BeaconManager beaconManager;
private TextView text;
@Override
protected void onCreate(Bundle saveInstanceState){
super.onCreate(saveInstanceState);
setContentView(R.layout.beacon_layout);
text=(TextView) findViewById(R.id.rangingText);
}
@Override
protected void onDestroy(){
super.onDestroy();
beaconManager.unbind(this);
}
@Override
public void onBeaconServiceConnect() {
ArrayList<Identifier> identifiers=new ArrayList<>();
identifiers.add(null);
Region region=new Region("all-beacons-region",identifiers);
try{
beaconManager.startRangingBeaconsInRegion(region);
} catch (RemoteException e) {
e.printStackTrace();
}
beaconManager.setRangeNotifier(this);
}
@Override
public void didRangeBeaconsInRegion(Collection<Beacon> beacons, Region region) {
Log.d("PROVA", "size: "+beacons.size());
for (Beacon beacon: beacons){
Identifier nameId=beacon.getId1();
Identifier instanceID=beacon.getId2();
Log.d("BEACON FOUND ", nameId + instanceID.toString() );
logToDisplay("BEACON FOUND");
}
}
@Override
public void onBackPressed(){
startActivity(new Intent(BeaconActivity.this, Main_Activity_login.class));
finish();
}
public void logToDisplay(final String string){
runOnUiThread(new Runnable() {
@Override
public void run() {
text.append(string + "\n");
}
});
}
@Override
public void onPause(){
super.onPause();
beaconManager.unbind(this);
}
@Override
public void onResume(){
super.onResume();
beaconManager=BeaconManager.getInstanceForApplication(getApplicationContext());
beaconManager.getBeaconParsers().add(new BeaconParser().setBeaconLayout("s:0-1=feaa,m:2-2=00,p:3-3:-41,i:4-13,i:14-19"));
beaconManager.bind(this);
}
在这里结束的是 StackRace：

实际上，似乎在 stackRace 中检测到了信标，但应用程序无法显示它。先感谢您。
