從圖庫中挑選視頻時，應用程序崩潰

2016-04-27 93 views

我無法嘗試在Android上選擇視頻。我正在使用下面的代碼來啓動該活動。從圖庫中挑選視頻時，應用程序崩潰

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

然後在OnActivityResult回調中，我使用下面的代碼來獲取數據的URI。

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); 
      } 
     } 
    }

該應用程序在圖庫打開後不久崩潰。我使用Android版本4.0.3的Sony Xperia ion來調試應用程序。我第一次測試我的代碼時，它運行正常，但現在每次圖庫打開時，應用程序都會崩潰。

這裏是我的全部的logcat：

我已經安裝在OnActionResultActivity的開始，但在調試前的應用程序崩潰的斷裂點得到的存在。有沒有人有任何想法如何從視頻選擇器獲取視頻數據？

我無法用C＃術語解釋這一點，但是您將'Uri'視爲包含文件系統上文件的路徑，這通常是不正確的。 – CommonsWare

我在我的項目中的其他地方使用相同的代碼，它工作正常。調試器沒有達到這一點，注意到這一點，應用程序崩潰。 –

呼叫startActivityForResult通過在取行動，你想要的視頻用戶從這樣的選擇：

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

然後重寫onActivityResult監聽用戶作出選擇。

@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(); 
} 
}

希望這會有所幫助，如果是的話，那麼請接受我的回答。 :)

很感謝。我會試試這個。儘管使用相同的代碼，我可以選擇一個圖像。 –

這對我有用！非常感謝！！！ :) –
