android altbeacon bluetooth low energy -


i trying scan beacons bluetooth low energy , altbeacon-library on samsung galaxy s5, , maybe did not understand correctly, or can't running.

a part of manifest looks this:

<uses-sdk android:minsdkversion="18" android:targetsdkversion="21" />  <uses-permission android:name="android.permission.bluetooth" /> <uses-permission android:name="android.permission.bluetooth_admin" />  <application .... <service     android:name=".beaconscanner"     android:icon="@drawable/ic_launcher"     android:label="beaconscanner" > </service> ....

i scanning beacons inside service:

public class beaconscanner extends service implements beaconconsumer {  private beaconmanager beaconmanager; private dbhelper mydb;  @override public int onstartcommand(intent intent, int flags, int startid) {        mydb = new dbhelper(this);       if (build.version.sdk_int >= 19 && getpackagemanager().hassystemfeature(packagemanager.feature_bluetooth_le)) {           // ble           beaconmanager.setandroidlscanningdisabled(true);       } else {           // kein ble        }       beaconmanager = beaconmanager.getinstanceforapplication(this);       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"));       beaconmanager.setforegroundbetweenscanperiod(15000l);       beaconmanager.setbackgroundbetweenscanperiod(15000l);       beaconmanager.bind(this);        return service.start_sticky; }  @override public void ondestroy() {     super.ondestroy();     beaconmanager.unbind(this); }  @override public ibinder onbind(intent intent) {     return null; }  @override public void onbeaconserviceconnect() {     beaconmanager.setrangenotifier(new rangenotifier() {          @override         public void didrangebeaconsinregion(collection<beacon> beacons, region region) {             if (beacons.size() > 0) {                 for(beacon beacon : beacons)                 {                     if (beacon != null && beacon.getid1() != null) {                         system.out.println("id1: " + beacon.getid1().tostring());                         system.out.println("id2: " + beacon.getid2().tostring());                         system.out.println("id3: " + beacon.getid3().tostring());                         string majorminor = beacon.getid2().tostring() + "-" + beacon.getid3().tostring();                         system.out.println(majorminor);                         long count = mydb.beaconexists(majorminor);                         system.out.println(count);                         if (count == 0) {                             getandinsertbeacondataset(mydb, majorminor);                             system.out.println("inserted beacon: " + majorminor);                         }                     }                 }             }         }     });      try {         beaconmanager.startrangingbeaconsinregion(new region("trewysuniquebeaconregion", null, null, null));     } catch (remoteexception e) {      } }  private boolean getandinsertbeacondataset(dbhelper dbhelper, string beaconid) {     try {         beacongetter beacongetter = new beacongetter();         return beacongetter.execute(dbhelper, beaconid).get();     } catch (exception e) {         return false;     } }  }

i checked, if phone able use bluetooth low energy, , is. if bluetooth not activated message library:

06-15 09:16:46.399: w/cycledlescanner(22748): bluetooth disabled.  cannot scan beacons.

if activate bluetooth, library working fine , beacon in range.

so maybe understood wrong, need activate bluetooth on android use bluetooth low energy? thought possible bluetooth-signals without activating bluetooth?

if possible scan bluetooth low energy without activating bluetooth: doing wrong?

any appreciated, in advance.

you must activate bluetooth use ble (low energy). otherwise can't scan beacons. device must support ble, modern devices support it.
