Question

我有一个安装了BackgroundGeolocation插件的Ionic应用程序。当我使用ionic cordova run android运行应用程序时，该应用程序运行正常，但是当我进行构建并在手机上手动安装时，我在启动应用程序时出现此错误：

Native: tried calling BackgroundGeolocation.configure, but the BackgroundGeolocation plugin is not installed

这是我的packaje.json文件：

  }
}

我有什么不对的，或者来自ionic-native或插件的错误？

Answer 1

发生在我身上的原因是我没有从正确的位置调用该函数（我是从服务而不是从app.component.ts调用它的。）

guide指出：

BackgroundGeolocation必须在app.ts 和...
之内称为

Answer 2

问题似乎在最新版本中得到解决，如下所示： https://github.com/ionic-team/ionic-native/issues/258

当ionic-native无法找到包装器定义中提供的pluginRef时，会发生插件未安装错误。 pluginRef设置为plugins.backgroundGeoLocation而不是backgroundGeolocation

背景地理位置插件不适用于Android版本
