Problems getting Bitmap from Camera taken image onto ImageView

I want to let the user set something of a contact icon, the user can either take a picture or choose one from the gallery. I have the following start activity for result, noting I handle the two differently here, but they should instead be handled the same:

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    switch (requestCode) {
        case Constants.TAKE_PHOTO:
            if (resultCode == RESULT_OK) {
                Uri selectedImage = data.getData();
                File file = new File(selectedImage.getPath());
                mPhoto = decodeFile(file);
                Bitmap croppedImage = cropImage(mPhoto);
                Bitmap resized = Bitmap.createScaledBitmap(croppedImage, 100, 100, true);
                Bitmap finalPhoto = getRoundedRectBitmap(resized, 100);
                imageView.setImageBitmap(finalPhoto);
            }
            break;

        case Constants.CHOOSE_PHOTO:
            if (resultCode == RESULT_OK) {
                Uri selectedImage = data.getData();
                imageView.setImageURI(selectedImage);
            }
            break;
    }

The second case, CHOOSE_PHOTO works. I choose a photo from the gallery, it gets placed in the ImageView. The thing is, the methods I've created in the first case, TAKE_PHOTO are kind of important, the Bitmap gets reshaped into a circle and cropped accordingly; for small sized pictures this worked exactly how I wanted it to. The main error was Out of Memory. I looked into it on SO and the found the following method to handle this:

private Bitmap decodeFile(File f) {
    try {
        //Decode image size
        BitmapFactory.Options o = new BitmapFactory.Options();
        o.inJustDecodeBounds = true;
        BitmapFactory.decodeStream(new FileInputStream(f), null, o);

        //The new size we want to scale to
        final int REQUIRED_SIZE = 70;

        //Find the correct scale value. It should be the power of 2.
        int scale = 1;
        while (o.outWidth / scale / 2 >= REQUIRED_SIZE && o.outHeight / scale / 2 >= REQUIRED_SIZE)
            scale *= 2;

        //Decode with inSampleSize
        BitmapFactory.Options o2 = new BitmapFactory.Options();
        o2.inSampleSize = scale;
        return BitmapFactory.decodeStream(new FileInputStream(f), null, o2);
    } catch (FileNotFoundException e) {
    }
    return null;
}

I thought that this would take Bitmap dimensions, record things before loading Bitmap into memory, then scale the Bitmap before loading it until OOM error was avoided entirely. However, when I ran the code the app still crashed upon trying to confirm a taken photo for selection, as if an OOM error had indeed occurred. I had the following Logcat at the time of the crash:

I've been looking into this for the greater part of a few hours and still can't seem to figure out how I can effectively load the Bitmap. I looked into the Android Dev site, where they had a useful tutorial on handling large Bitmaps, but their solution was very similar to the one I found on SO in the decodeFile method. What am I missing here?

You can try this for getting bitmap in ActivityForResult()

    Bitmap picture = (Bitmap) data.getExtras().get("data");
    ByteArrayOutputStream stream = new ByteArrayOutputStream();
    picture.compress(Bitmap.CompressFormat.JPEG, 100, stream);
