当手动关闭并重新启动应用程序时，Gluon无法加载本机插件
我正在尝试将Gluon用于应用程序 . 我需要在后台运行一个需要永远保持活动的服务，因为它一直在轮询服务器上的更改，并且需要在事情发生变化时通知用户 .
胶子样本目录没有一个说明如何运行后台服务的示例 . https://gluonhq.com/developers/samples/
我已经在这个帖子上发布的答案后面实现了后台服务（还有其他几个在SO上） . Creating an Android background service that continuously polls a REST API for data使用纯Android设置和运行后台服务似乎很容易 .
我已经按照Gluon插件示例来实现我自己的Android服务插件 .
我可以在后台启动该服务 . 但是，如果我手动关闭所有应用并尝试再次启动应用，则Gluon会失败 . 该服务确实在后台运行 . 但该应用程序似乎让所有的混乱，并无法正确加载天真的插件 .
- 在应用程序init方法中调用此方法时，查找我的服务的Android实现并抛出此错误：
Services.get(MobilePlatformService.class).get()

- 初始化时，应用程序需要应用程序目录的位置 . 但是，由于该服务未能找到Android实现，我无法获取应用程序目录

那么，如何正确启动Gluon应用程序以便正确加载Android（或ios）本机服务？如果在Gluon样本页面上发布了工作后台服务样本，那么它对开发人员非常有用 .
