Question

为什么即使imageUri不为null或为空，Parcel文件描述符也会抛出FileNotFounException。我使用Intent从我的库中选择了一个文件。我还提供“imageUri”的值，它会打印出来。

      ParcelFileDescriptor percelFileDescriptor;
      Toast.makeText(getApplicationContext(),""+imageUri.toString(),Toast.LENGTH_LONG).show();
      try {
           percelFileDescriptor = getContentResolver().openFileDescriptor(imageUri, "r");
           image = BitmapFactory.decodeFileDescriptor(percelFileDescriptor.getFileDescriptor());
           modified_img_bitmap = image;
           percelFileDescriptor.close();
           picked_image.setImageBitmap(image);
           } catch (FileNotFoundException e) {
           System.out.println("File Not Found: " + e.toString());
           Toast.makeText(getApplicationContext(),"File not found: "+e.toString(),Toast.LENGTH_LONG).show();
           } catch (IOException e) {
           Toast.makeText(getApplicationContext(),"IO Error: "+e.toString(),Toast.LENGTH_LONG).show();
           System.out.println("IO Exception: " + e.toString());
           }
      }
