你好，代号一队！
我已经实现了地理围栏功能。最近对 Codename One 的 Android 构建过程进行更改后，我遇到了一个专门针对 Android 设备的错误。在地理围栏区域内添加地理围栏时，应用程序会崩溃。 iOS 设备上不会出现此问题。
问题详情：
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());
}
在 Android 上的 GeoFence 区域内添加 GeoFence 时，什么可能导致应用程序崩溃？如何调试并修复此问题，以便无论设备当前位置如何，地理围栏都能正常工作？
我非常感谢您提供的任何帮助。任何见解或建议将不胜感激！任何见解或建议将不胜感激！
最诚挚的问候， 奥斯卡

我做了以下修复，应该可以在 2024 年 5 月 24 日发布的版本上使用。但是，我不确定它是否能解决问题，因为堆栈中的行号不正确。
