Android: BitmapFactory returning java.io.FileNotFoundException error, even though image is saved to external storage

Question

I am trying to make an app in which the user can take a picture to attach to a post. For the image capturing, saving and handling part I was following the official developer guide (using their code snippets). I have no problem with taking the picture and saving it to external storage (I have found the pictures on my hard drive), but when I need to access the file for displaying the image in the view (or for starting a media scanner intent), I get an error indicating that the file was not found.

Here are some parts of my code:

File creation:

private File createImageFile() throws IOException {
    // Create an image file name
    String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
    String imageFileName = "JPEG_" + timeStamp + "_";
    File storageDir = Environment.getExternalStoragePublicDirectory(
            Environment.DIRECTORY_PICTURES);
    File image = File.createTempFile(
            imageFileName,  /* prefix */
            ".jpg",         /* suffix */
            storageDir      /* directory */
    );

    // Save a file: path for use with ACTION_VIEW intents
    mCurrentPhotoPath = "file:" + image.getAbsolutePath();
    return image;
}

Image capture intent:

private void dispatchTakePictureIntent() {
    Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    // Ensure that there's a camera activity to handle the intent
    if (takePictureIntent.resolveActivity(getActivity().getPackageManager()) != null) {
        // Create the File where the photo should go
        File photoFile = null;
        try {
            photoFile = createImageFile();
        } catch (IOException ex) {
            // Error occurred while creating the File
            Toast.makeText(getActivity(), ex.getMessage(), Toast.LENGTH_SHORT).show();
        }
        // Continue only if the File was successfully created
        if (photoFile != null) {
            takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT,
                    Uri.fromFile(photoFile));
            startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
        }
    }
}

Displaying small image:

private void setPic() {
    // Get the dimensions of the View
    int targetW = 30;
    int targetH = 50;

    // Get the dimensions of the bitmap
    BitmapFactory.Options bmOptions = new BitmapFactory.Options();
    bmOptions.inJustDecodeBounds = true;
    BitmapFactory.decodeFile(mCurrentPhotoPath, bmOptions);
    int photoW = bmOptions.outWidth;
    int photoH = bmOptions.outHeight;

    // Determine how much to scale down the image
    int scaleFactor = Math.min(photoW/targetW, photoH/targetH);

    // Decode the image file into a Bitmap sized to fill the View
    bmOptions.inJustDecodeBounds = false;
    bmOptions.inSampleSize = scaleFactor;
    bmOptions.inPurgeable = true;

    Bitmap bitmap = BitmapFactory.decodeFile(mCurrentPhotoPath, bmOptions);
    img_added.setImageBitmap(bitmap);
}

Adding image to gallery:

private void galleryAddPic() {
    Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
    File f = new File(mCurrentPhotoPath);
    Uri contentUri = Uri.fromFile(f);
    mediaScanIntent.setData(contentUri);
    getActivity().sendBroadcast(mediaScanIntent);
}

And then when I run the app, after taking the picture I get this in logcat:

E/BitmapFactory﹕ Unable to decode stream: java.io.FileNotFoundException: file:/storage/emulated/0/Pictures/JPEG_20150731_114600_153874160.jpg: open failed: ENOENT (No such file or directory)

I set the permission to write to external storage in the manifest and I can see the pictures saved to my storage, so the file exists. I was really just doing everything according to the official guide, so I have no idea what is going wrong. Can someone help me? Thanks in advance!

EDIT:

I have changed the line

mCurrentPhotoPath = "file:" + image.getAbsolutePath();

to

mCurrentPhotoPath = image.getAbsolutePath();

so the createImageFile() function now looks like this:

private File createImageFile() throws IOException {
    // Create an image file name
    String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
    String imageFileName = "JPEG_" + timeStamp + "_";
    File storageDir = Environment.getExternalStoragePublicDirectory(
            Environment.DIRECTORY_PICTURES);
    File image = File.createTempFile(
            imageFileName,  /* prefix */
            ".jpg",         /* suffix */
            storageDir      /* directory */
    );

    // Save a file: path for use with ACTION_VIEW intents
    mCurrentPhotoPath = image.getAbsolutePath();
    return image;
}

This solved my problem with displaying the image, but the photo still does not appear in my gallery. When I log the value of the URI passed to the media scan intent, I get this:

file:///storage/emulated/0/Pictures/JPEG_20150731_135706_153874160.jpg

Could this be the problem (although I get it from the image file with Uri.fromFile method, so this should be a proper URI)? Or what else could cause the problem?

Change this line

mCurrentPhotoPath = "file:" + image.getAbsolutePath();

to

mCurrentPhotoPath = image.getAbsolutePath();
