PushWoosh Xamarin Forms Android 注册异常

Question

我一直在尝试在我现有的 Xamarin Forms (PCL) 项目中实施 PushWoosh 的推送通知系统，到目前为止，它与 iOS 完美配合。在将其添加到 Android 时，我在启动时面临崩溃，尽管我已经一个字母一个字母地遵循 the guide for Xamarin Forms for Android。

由于未处理的异常，应用程序在启动时崩溃了。

我很高兴逐行评论以找出导致此错误的原因，似乎 manager.RegisterForPushNotifications(); 执行了导致该崩溃的代码。

在调试日志中进一步调查后，似乎是 ShortcutBadger 无法解析意图的问题。

我已经运行物理设备上的应用程序，完全是最新的：

三星 Galaxy S4
（华硕）Google Nexus 7

我正在使用 Visual Studio 2017 社区。

请注意，出于保密目的，我已经重命名了项目名称、包、PushWoosh 应用程序 ID 和 FCM 应用程序 ID。

Answer 1

我通过将 Xamarin.GooglePlayServices.Gcm 依赖项更新到最新版本 42.1021.1 解决了我的问题，而我的是 29.x.x.

正如 Mike 在评论中所说，我必须确保一切都是最新的，因为 PushWoosh 不需要高版本的关键依赖项，例如 Google Play 服务，而它们可能会崩溃该应用程序（如果已过时）。他们应该在这一点上更加严格！
