Can't create handler inside thread that has not called Looper.prepare()

1

请教，调用beaconManager = new com.aprilbrother.aprilbrothersdk.BeaconManager(getActivity());方法不执行，报出这个错误,求解

2

beaconManager 不支持在fragment中初始化

可是这并不是在fragment初始化的

贴下你的代码看看？

public class BaseActivity extends PluginBase{

 BeaconManager beaconManager;
BluetoothAdapter bluetoothAdapter;
BluetoothManager bluetoothManager;
final	Region region = new Region("apr", null, null, null) ;
ArrayList<Beacon> mybeacon;
 boolean mScanning;
 Handler mHandler;
 static final long SCAN_PERIOD = 10000;
 String datastring;

看看？贴啦

试试创建Handler时用mHandler = new Handler(mContext.getMainLooper());
指定个Looper

好的 试试
