奇怪的运行时异常

Question

我最近删除了我的 Netbeans 缓存文件夹 (/appdata/local/netbeans/cache/)，我的使用原生 google 地图插件的代号应用程序一直在运行。我在启动时遇到运行时异常。下面是堆栈跟踪。

我已经从 NB 中删除了 cn1 插件，下载了本地地图 cn1lib 的新副本，清理并构建了我仍然遇到同样的错误...请帮助。

Answer 1

这开始发生在另一个我知道的用户身上（但不是每个人都令人惊讶），这是由于更改以删除位置管理器中的地图。我们不得不删除它们，因为 Google 对地图密钥生成策略变得过于严格。

我们已经解决了这个问题，将在今天晚些时候或明天早上 post 解决。
