您是否需要運行Nuget軟件包安裝？ –

這是Xamarin Studio還是Visual Studio？你可能沒有安裝java SDK和android SDK＆NDK。如果是Visual Studio，我可以幫助您進行安裝。 – peterincumbria

是的，即時通訊使用Visual Studio進行Xamarin開發，如果您有任何問題，請分享鏈接。 –

您可能會安裝Nuget適用於各個平臺的軟件包。

如果沒有，關閉你的Visual Studio並重新打開，它有時會解決你的問題。仍然得到相同的問題，然後嘗試更新「Xamarin.Android.Support.v7.AppCompat」&「Xamarin.Forms」Nuget包。

不要忘記爲整個解決方案「安裝軟件包」。

我想更新這兩個軟件包，但沒有安裝。讓我們假設我試圖安裝Xamarin.Android.Support.v7.AppCompat，它需要依賴dll。安裝會以異常關閉。 –

現在我再次嘗試安裝「Xamarin.Android.Support.v7.AppCompat」，但我收到以下錯誤消息。 **嚴重\t代碼\t說明\t項目\t文件\t線\t抑制狀態錯誤\t \t無法安裝程序包「Xamarin.Android.Support.v4 23.0.1.3」。您正在嘗試將此軟件包安裝到以'.NETPortable，Version = v4.5，Profile = Profile259'爲目標的項目中，但該軟件包不包含任何與該框架兼容的程序集引用或內容文件。有關更多信息，請聯繫軟件包作者。 \t \t ** –
