Android interface implementation for multiple screen sizes and densities

I'm developing an application and i need it to fit all screen sizes and densities. I created 4 folders for the resources (drawable-ldpi,drawable-mdpi,drawable-hdpi,drawable-xhdpi) and 4 xml layouts. But i'm confused a little about many points:

1- If I have a Samsung Galaxy tab 10.1 (mdpi screen) with a 1280 x 800 screen size and a Samsung Gio (mdpi screen) with a 320 x 480 screen size, how can I make the "layout-mdpi" folder including the xml layout file for medium dpi, fits these 2 devices having the same dpi but 2 different screen sizes (Galaxy tab is much bigger than Samsung Gio)?

2- I'm creating my png's using Photoshop, these png's must be saved with 320dpi,160dpi,240dpi..? Or all the resources must be saved in 72 dpi but different sizes?

3- I tested a star icon on my Samsung Galaxy tab 10.1 (mdpi screen) having 32x32px size, dunno why my icon is blurred!

You have to make all 4 different sizes images and put that images according to folder.And also set the property in menifest like this.

<supports-screens
        android:anyDensity="true"
        android:largeScreens="true"
        android:normalScreens="true"
        android:smallScreens="true" />
