我一直試圖在我現有的Xamarin Forms（PCL）項目中實現PushWoosh的推送通知系統，到目前爲止，它與iOS完美協作。當涉及到將其添加到Android，儘管事實上我已經按照字母the guide for Xamarin Forms for Android的字母順序，但我仍然面臨崩潰。PushWoosh Xamarin在註冊時形成Android異常

由於未處理的異常，應用程序在啓動時崩潰。

我已經開始逐行評論，發現是什麼原因導致了這個錯誤，好像它是manager.RegisterForPushNotifications();，它執行負責該崩潰的代碼。

後的調試日誌進一步調查，這似乎是與ShortcutBadger是無法解決的意圖問題。

我已經跑了物理設備的應用程序，完全處於最新：

三星Galaxy S4
（華碩）谷歌Nexus 7

我使用Visual Studio 2017社區。

錯誤：https：//github.com/leolin310148/SortcutBadger/issues/90 – SushiHangover

感謝您的回答。不幸的是，我已經閱讀過這篇文章，正如他們最後說的那樣，這個問題已經關閉，沒有有效的解決方案。 –

它的開放源代碼，您可以隨時修改源代碼以使用您正在使用的啓動器。核心問題是你正在使用的啓動器沒有'android.intent.action.BADGE_COUNT_UPDATE'意圖定義 – SushiHangover

我解決了我的問題，通過更新Xamarin.GooglePlayServices.Gcm依賴關係到最新版本42.1021.1而我的是29.x.x。

正如Mike在評論中所說的，我必須確保一切都是最新的，因爲PushWoosh不需要高版本的關鍵依賴關係，例如Google Play服務，但它們可能會在應用程序過時時崩潰。在這一點上他們應該更具限制性！
