Android notification small and big images sizes

Question

I'm trying to figure out what is the image size used for the notifications in ICS+
As shown here :

I've tried setting the ic_launcher but it was too big and appear to be cut on the image. (48dp for MDPI) So now i'm using ic_stat_notify which is 24dp for MDPI and it looks pretty small.
I went through all the documentation and I couldn't find any mention of these icons size.

Thank you

You can find more about these icons dimensions in Iconography part of the documentation here

You can use this website in order to calculate the exact dimensions

Answer 2

If you are implementing your view through a xml layout, you can always scale the ImageView to fit a specific size.

From Android: resizing imageview in XML comes the following example:

<ImageView [...]
  android:maxWidth="42dp"  
  android:maxHeight="42dp"  
  android:scaleType="fitCenter"
  android:adjustViewBounds="true"
  />
