Android camera-intent保存图像并在imageView FileNotFoundException中显示

Question

我试图将最近拍摄的图像放入imageView中。我得到正确的路径，图像在那里，但我最终在FileNotFoundException。任何人都知道接缝是什么问题？

else if (requestCode == CAMERA_RESULT) {

            File file = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES).getPath(), pictureName.toString());
            Log.d("MainActivity", file.toString()); // It's the right filePath
            Uri uri = Uri.fromFile(file);


            Bitmap bitmap;
            try {

                bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), uri);
                mImageView.setImageBitmap(bitmap);

                Log.d("MainActivity", bitmap.toString());

            } catch (FileNotFoundException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }

这是我做的另一个尝试

else if (requestCode == CAMERA_RESULT) {
        File file = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES).getPath(), pictureName.toString());
        Uri uri = Uri.fromFile(file);
        InputStream inputStream;
        try {
            inputStream = getContentResolver().openInputStream(uri);
            BitmapFactory.Options options = new BitmapFactory.Options();
            Bitmap bitmap = BitmapFactory.decodeFile(file.getAbsolutePath(), options);
            mImageView.setImageBitmap(bitmap);
            Log.d("MainActivity", uri.toString());
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

}
