Android端GeoFence添加崩溃问题求助（Codename One）
我在应用中实现了GeoFence功能，Codename One的Android构建流程更新后，出现了仅Android设备存在的Bug：当设备处于GeoFence区域内时添加GeoFence，应用会崩溃，iOS设备无此问题。
问题详情
- GeoFence在iOS设备上运行正常
- Android设备处于GeoFence区域外时，添加GeoFence无异常
- Android设备处于GeoFence区域内时添加，应用会弹出“This app has a bug”提示并崩溃
相关代码
Geofence gf = new Geofence(fenceID, location, courtDiameter, -1); try { LocationManager.getLocationManager().addGeoFencing(GeofenceWhoPlaysImpl.class, gf); } catch (Exception eLoc) { UserInfo.setLogWP("Location! Add GeoFence error: " + eLoc.getMessage()); }
核心异常
java.lang.RuntimeException: Unable to start receiver com.codename1.location.BackgroundLocationBroadcastReceiver: java.lang.NullPointerException: Attempt to invoke virtual method 'boolean com.google.android.gms.location.GeofencingEvent.hasError()' on a null object reference

请问该问题的触发原因是什么？如何进行调试并修复，使GeoFence无论设备当前位置如何都能正常工作？
