android 4.0 以上平台选择图片报错Attempted to access a cursor after it has been closed.

 Caused by: android.database.StaleDataException: Attempted to access a cursor after it has been closed.

选择图片后 onActivityResult中的代码如下：

 Uri uri = data.getData();
                if (uri != null)
                {
                    mFilePath = new URIUtils().getPathFromUri(uri);
                }

解决办法如注释中的所示。 4.0以上平台会自动关闭cursor

 protected String getPath(Uri uri)
     {
         String filePath = "";

         String[] projection = {MediaColumns.DATA };
         Cursor cursor = managedQuery(uri,
             projection,
             null,
             null,
             null);

         if (cursor != null)
         {
             int columnIndex = cursor.getColumnIndexOrThrow(MediaColumns.DATA);
             cursor.moveToFirst();
             filePath = cursor.getString(columnIndex);
             try
             {
                 //4.0以上的版本会自动关闭 (4.0--14;; 4.0.3--15)
                 if(Integer.parseInt(Build.VERSION.SDK) < 14)
                 {
                     cursor.close();
                 }
             }catch(Exception e)
             {
                 Log.error(TAG, "error:" + e);
             }
         }

         return filePath;
     }
