Question

当使用指定区域的信标时，我正在使用Android 4.4并在监控回调中收到警告消息。

我用于监控的代码是

@Override
public void onIBeaconServiceConnect() {

    iBeaconManager.setMonitorNotifier(new MonitorNotifier() {
        @Override
        public void didEnterRegion(Region region) {
          Log.e("didEnterRegion","I just saw an iBeacon for the first time!");       
        }

        @Override
        public void didExitRegion(Region region) {
            Log.e("didExitRegion","I no longer see an iBeacon");
        }

        @Override
        public void didDetermineStateForRegion(int state, Region region) {
            Log.e("didDetermineStateForRegion","I have just switched from seeing/not seeing iBeacons: "+state);   

            if(state == MonitorNotifier.INSIDE){
                try {
                    //Start Ranging in the Region.
                    iBeaconManager.startRangingBeaconsInRegion(region);
                } catch (RemoteException e) { 
                    System.out.println(e);
                }

            }
            else if(state == MonitorNotifier.OUTSIDE){
                try {
                    //Stop Ranging in the Region.
                    iBeaconManager.stopRangingBeaconsInRegion(region);
                } catch (RemoteException e) { 
                    System.out.println(e);
                }

            }
        }
        });

        try {
            //Start Monitoring in the Region.
            iBeaconManager.startMonitoringBeaconsInRegion(region);
        } catch (RemoteException e) { 
            System.out.println(e);
        }

我在logcat中找到的警告信息是

此警告显示的是Android iBeacon Library的过期版本，0.7或更早版本。最新版本是0.7.6，不会有此警告。简单的解决方案是简单地升级到可用库的最新版本here.

警告与iBeacon数据在图书馆的后台服务和您的应用之间传递的方式有关。早期版本的库使用了＆＃34;隐含意图＆＃34;传递这些信息，理论上如果同时使用该库的两个应用程序在电话上，则理论上会导致iBeacon数据到错误的应用程序。出于开发目的，它并不重要，但如果在生产应用程序中使用它，则应使用最新的库版本。

IBeacon收到警告Implcit意图在MonitorNotifier的回调上是不安全的
