要解决"Android Beacon Library无法看到任何信标"的问题,你可以尝试以下解决方法:
BluetoothAdapter bluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
if (bluetoothAdapter != null && !bluetoothAdapter.isEnabled()) {
Intent enableBtIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
startActivityForResult(enableBtIntent, REQUEST_ENABLE_BT);
}
private static final int REQUEST_FINE_LOCATION_PERMISSIONS = 1;
// 在onCreate方法中调用
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (checkSelfPermission(Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
requestPermissions(new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, REQUEST_FINE_LOCATION_PERMISSIONS);
}
}
// 处理权限请求回调
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
if (requestCode == REQUEST_FINE_LOCATION_PERMISSIONS) {
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
// 权限已授予,可以开始搜索信标
}
}
}
@Override
public void onCreate() {
super.onCreate();
BeaconManager beaconManager = BeaconManager.getInstanceForApplication(this);
beaconManager.getBeaconParsers().add(new BeaconParser()
.setBeaconLayout(BeaconParser.EDDYSTONE_UID_LAYOUT));
beaconManager.bind(this);
}
@Override
public void onBeaconServiceConnect() {
beaconManager.addRangeNotifier(new RangeNotifier() {
@Override
public void didRangeBeaconsInRegion(Collection beacons, Region region) {
// 处理检测到的信标
}
});
try {
beaconManager.startRangingBeaconsInRegion(new Region("myRangingUniqueId", null, null, null));
} catch (RemoteException e) {
e.printStackTrace();
}
}
@Override
public void onDestroy() {
super.onDestroy();
beaconManager.unbind(this);
}
希望这些解决方法能够帮助你解决问题!
