java - android-Altbeacons 路径错误

Question

我尝试使用 altBeacon 库查找 iBeacon，但收到此错误:

我下载了 altBeacon 库并移动到我的项目的“library”文件夹中。然后我将 compile 'org.altbeacon:android-beacon-library:2+' 行放入应用程序的 gradle 中。我使用的类是:

     public class MainActivity extends Activity implements BeaconConsumer{


        private static final String TAG = "BeaconReferenceApp";
        private BeaconManager beaconManager;

        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            beaconManager = BeaconManager.getInstanceForApplication(this);
                beaconManager.getBeaconParsers().clear();
    //i think that i should use "0x0215"
                beaconManager.getBeaconParsers().add(new BeaconParser().
setBeaconLayout("m:2-3=0x0215,i:4-19,i:20-21,i:22-23,p:24-24,d:25-25"));
                beaconManager.bind(this);

   //I link the activity with the layout
            setContentView(R.layout.activity_main);
        }

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


            @Override
            public void onBeaconServiceConnect() {
    //I use the ID of my beacon
                final Region region = new Region("myBeacons", Identifier.parse("A7AE2EB71F004168B99BA749BAC1CA64"), null, null);
                beaconManager.setMonitorNotifier(new MonitorNotifier() {
                    @Override
                    public void didEnterRegion(Region region) {
                    try {
                        Log.d(TAG, "didEnterRegion");
                        beaconManager.startRangingBeaconsInRegion(region);
                    } catch (RemoteException e) {
                        e.printStackTrace();
                    }
                }

                @Override
                public void didExitRegion(Region region) {
                    try {
                        Log.d(TAG, "didExitRegion");
                        beaconManager.stopRangingBeaconsInRegion(region);
                    } catch (RemoteException e) {
                        e.printStackTrace();
                    }
                }

                @Override
                public void didDetermineStateForRegion(int i, Region region) {

                }
            });

//i set the notifier
            beaconManager.setRangeNotifier(new RangeNotifier() {
                @Override
                public void didRangeBeaconsInRegion(Collection<Beacon> beacons, Region region) {
                    for (Beacon oneBeacon : beacons) {
                        Log.d(TAG, "distance: " + oneBeacon.getDistance() + " id:" + oneBeacon.getId1() + "/" + oneBeacon.getId2() + "/" + oneBeacon.getId3());
                        }
                    }
                });

                try {
                    beaconManager.startMonitoringBeaconsInRegion(region);
                } catch (RemoteException e) {
                    e.printStackTrace();
                }

            }
        }

Answer 1

Android 6 现在要求应用程序扫描 BLE 信标以获得访问位置的运行时权限。

您可以在我的博客文章中阅读有关如何执行此操作的完整详细信息:
