ギャラリーから動画を選択するとアプリがクラッシュする

Androidで動画を選択する際に問題が発生しました。私は以下のコードを使って活動を開始しています。ギャラリーから動画を選択するとアプリがクラッシュする

var intent = new Intent(); 
      intent.SetType("video/*"); 
      intent.SetAction(Intent.ActionGetContent); 
      this.StartActivityForResult(Intent.CreateChooser(intent, "Select video"), 200);

次に、OnActivityResultコールバックでは、次のコードを使用してデータのURIを取得します。

public override void OnActivityResult(int requestCode, Result resultCode, Intent data) 
    { 
     base.OnActivityResult(requestCode, resultCode, data); 

     if (requestCode == 200 && resultCode == Result.Ok) 
     { 
      try 
      { 
       Android.Net.Uri contentURI = data.Data; 

       ICursor cursor = Activity.ContentResolver.Query(contentURI, null, null, null, null); 
       cursor.MoveToFirst(); 
       string documentId = cursor.GetString(0); 
       documentId = documentId.Split(':')[1]; 
       cursor.Close(); 

       cursor = Activity.ContentResolver.Query(
       Android.Provider.MediaStore.Video.Media.ExternalContentUri, 
       null, MediaStore.Video.Media.InterfaceConsts.Id + " = ? ", new[] { documentId }, null); 
       cursor.MoveToFirst(); 
       string selectedPath = cursor.GetString(cursor.GetColumnIndex(MediaStore.Video.Media.InterfaceConsts.Data)); 

       var fileBytes = System.IO.File.ReadAllBytes(selectedPath); 

       //await UploadFile(fileBytes); 

      } 
      catch (Java.Lang.Exception e) 
      { 
       System.Console.WriteLine(e.Message); 
      } 
     } 
    }

ギャラリーを開いた直後にアプリケーションがクラッシュします。私はアプリをデバッグするためにAndroidバージョン4.0.3でSony Xperiaイオンを使用しています。初めてコードをテストしたときに機能しましたが、今度はギャラリーが開くたびにアプリがクラッシュします。

私はこれをC＃の言葉で説明することはできませんが、ファイルシステム上のファイルへのパスが含まれているかのように 'Uri'を扱っています。 – CommonsWare

私は私のプロジェクトのどこかで同じコードを使用していますが、うまくいきます。デバッガはその点に達しておらず、アプリがクラッシュします。 –

コールstartActivityForResultピックアクションと、ユーザーがこのような中から選択したい動画を渡し：

startActivityForResult(new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Videos.Media.INTERNAL_CONTENT_URI), SELECT_VIDEO);

その後の選択をしたユーザーをリッスンするためにonActivityResultオーバーライドします。

@Override 
public void onActivityResult(int requestCode, int resultCode, Intent data) 
{ 
super.onActivityResult(requestCode, resultCode, data); if (requestCode == SELECT_VIDEO) 
if (resultCode == Activity.RESULT_OK) { 
    Uri selectedVIDEO = data.getData(); 
} 
}

これが役に立ったら、私の答えを受け入れてください。 :)
