不幸的是已經停止應用程序的Android運行時與模擬器

我是新的android應用程序開發（從昨天我纔開始學習android）。不幸的是已經停止應用程序的Android運行時與模擬器

然後當我運行模擬器，它給「不幸的是已停止」的消息，請幫我解決這個錯誤

MainActivity.cs

using System; 
using Android.App; 
using Android.Content; 
using Android.Runtime; 
using Android.Views; 
using Android.Widget; 
using Android.OS; 

namespace MediaPlayer.Android 
{ 
public class MainActivity : Activity 
{ 

    protected override void OnCreate(Bundle bundle) 
    { 
     base.OnCreate(bundle); 

     try 
     { 
      SetContentView(Resource.Layout.Main); 
     } 
     catch (Exception e) 
     { 
     } 

    } 
} 
}

模擬器不支持OpenGL，或者您已經實現了一個類並忘記實現其抽象方法。 – Devsil

我不這麼認爲。因爲我沒有在我的代碼中實現所有的東西。我在設計GUI。 –

有人幫助我。 plzzz –

首先，「不幸已經停止」是一個普遍的信息，意思是有一些一些未處理的異常。

現在，看着你的日誌，你可以找到你的程序有以下例外崩潰：

了java.lang.RuntimeException：無法找到應用 Mono.Android.Platform.ApiLevel_22或Xamarin.Android 。平臺！

這當然更有意義。這裏（https://forums.xamarin.com/discussion/10159/can-no-longer-run-android-applications-using-xamarin-4-2-and-xamarin-android-4-10-1）你可以找到類似問題的討論。解決方案提出有手動更改您的csproj文件：從

<AndroidUseLatestPlatformSdk>True</AndroidUseLatestPlatformSdk>

到

<AndroidUseLatestPlatformSdk>False</AndroidUseLatestPlatformSdk>

我想你應該試試這個。
