Путь к файлу видео для Android

У меня есть код, который предположительно находит путь к ранее выбранному видео в классе Async. Я искал SO, и все решения похожи, если не совпадают, но путь, который я получаю, всегда равен нулю, и когда я печатаю его, приложение выходит из строя.Путь к файлу видео для Android

код ниже:

// The file location of the image selected. 
      Uri selectedVideo = uris[0]; 

      String[] filePathColumn = { MediaStore.Video.Media.DATA }; 

      Cursor cursor = getContentResolver().query(selectedVideo, filePathColumn, null, null, null); 
      cursor.moveToFirst(); 

      int columnIndex = cursor.getColumnIndex(filePathColumn[0]); 
      String filePath = cursor.getString(columnIndex); 

      Log.i("INFO", filePath); 
      cursor.close();

@lassana Отредактировано Q –

Измените 'Log.i (« INFO », filePath);' to 'Log.i (« INFO »,« Path is : "+ filePath);' и вы избежите краха. Но вам нужно выяснить, почему это null, возможно, вы его на самом деле не нашли, или ищете неправильный столбец. –

EDIT:

Я уверен, что ваш код будет работать на 4,3 и ниже, но KitKat имеет некоторые изменения. Надеюсь, что это тема поможет:

Get real path from URI, Android KitKat new storage access framework

Android Gallery on KitKat returns different Uri for Intent.ACTION_GET_CONTENT

Вашего код выглядит правильно. Попробуйте:

String[] filePathColumn = { MediaStore.Video.VideoColumns.Data };

и, может быть, вы должны изменить свой запрос:

Cursor cursor = getContentResolver().query(selectedVideo, null, null, null, null);

Наконец, что это ваш URI? Это может быть Dropbox или другой аналогичный путь к локальному файлу.

Изменения не имеют значения ... My URI is-content: //com.android.providers.media.documents/document/video%3A11031 –

Какую версию Android вы используете? Кит-Кат? –

Да, я. Что-то изменилось? –
