Can't receive Intent.extras() from Camera after making a photo

I found it's a common problem with capturing photo and receiving full size photo instead of thumbnail (according to: http://developer.android.com/training/camera/photobasics.html ). Taking photo and receiving thumbnail is easy, but rest of tutorial seems to be uncomplete and not working. Anyone resolved it in easy way?

public class TakePhoto extends Activity{

static final int REQUEST_IMAGE_CAPTURE = 1;
static final int REQUEST_TAKE_PHOTO = 1;
private String mCurrentPhotoPath;
private ImageView mImageView;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.take_photo);

    mImageView = (ImageView) findViewById(R.id.imageView);

    dispatchTakePictureIntent();

}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == REQUEST_TAKE_PHOTO && resultCode == RESULT_OK) {
        Bundle extras = data.getExtras();
        Bitmap imageBitmap = (Bitmap) extras.get("data");
        mImageView.setImageBitmap(imageBitmap);
    }
}

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(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
            Log.i("ASD", ex.toString());
        }
        // Continue only if the File was successfully created
        if (photoFile != null) {
            takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT,
                    Uri.fromFile(photoFile));
            startActivityForResult(takePictureIntent, REQUEST_TAKE_PHOTO);
        }
    }
}

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;
}

}

I would not expect data to be null there. However, there should not be any extras on that Intent. You only look for the "data" extra if you are not specifying EXTRA_OUTPUT. If you are specifying EXTRA_OUTPUT, you go get the photo from the path that you provided in EXTRA_OUTPUT, and you ignore the Intent delivered to onActivityResult().

With regards to the null data Intent itself, that may be something peculiar to the camera app that you are using. Please bear in mind that using ACTION_IMAGE_CAPTURE means that you are relying upon a third-party app to take the picture, and third-party apps can have bugs.
