我现在可以构建整个解决方案＆amp;成功运行它。但是，当我尝试初始化IMvxGeoLocationWatcher时，它崩溃了。代码＆amp;输出是 -
private IMvxGeoLocationWatcher _geoWatcher;
public void StartGettingLocation(Action<MvxCoordinates> response)
{
Log.Info("LocationService->StartGettingLocation");
// crashes on this line -
if (_geoWatcher == null) _geoWatcher = this.GetService<IMvxGeoLocationWatcher>();
输出 -

感谢您的帮助。
答案 0 :(得分：0)
如果没有内部异常，很难知道出了什么问题 - 抱歉。
我猜测初始化geowatcher存在一些问题 - 要么是因为：
Cirrious.MvvmCross.Plugins.Location.PluginLoader.Instance.EnsureLoaded() 教程应用使用位置插件：https://github.com/slodge/MvvmCross/tree/vnext/Sample%20-%20Tutorial/Tutorial/Tutorial.UI.Touch
教程是否适合您？如果确实如此，那么你可能需要考虑比较两者。
如果崩溃仍然存在，那么可能： - 如果可以，发布内部异常？ - 或者发布一个小型仓库来解决这个问题 - 我当然需要比我在这2行代码中看到的更多的代码。
很抱歉缺少文档。我现在正在努力为新发布的v3创建适当的文档和教程 - 但这都是自筹资金！
