Image View doesn't show clear image defined in xml

In my code I want to set a default image for my imageview. All my images are of 174px X 174px. So, I want the default image to be same size. This is my xml for image view

//....code

<ImageView
    android:id="@+id/ivCover"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:layout_alignParentTop="true"
    android:contentDescription="Default Image"
    android:src="@drawable/default_cover" />


//....some other code

Now, my default_cover.jpg is also 174px X 174px. But it shows a smaller image. I've tried all

android:scaleType="centerInside"
android:scaleType="center"
android:scaleType="matrix"

even when most of them were senseless for me but still I tried all of 'em & none of them works. Then I specified the height & width of image by specifying

android:layout_width="174px"
android:layout_height="174px"

(I know using dp is better than px but because this image size is fixed & I was just testing it). So it shows

default image which doesn't look good[default image]

while when loaded from an external url using 

Bitmap bitmap = BitmapFactory.decodeStream((InputStream) new URL(url_source_for_image).getContent());
ivCover.setImageBitmap(bitmap);

desired image

clear image with desired image quality[]

The two pictures may not look very different here but the difference is very clear on my android device. And please don't say that I didn't try other solutions.. Here is a list of links of so itself..

Sounds like the answer is to use drawable-nodpi. For future reference, if you have the same named image in both the ldpi/hdpi/etc and in no-dpi, I think the no-dpi one will be ignored.
