I can't really understand what to do with diffrent phone/tablet screens. I reference retrieval google nexus s screen looks perfectly (800x480) but especially on tablets looks terrible. at left corner 1/4 size. all rest of screen is just junk.
what I do on my xml is like this;
<LinearLayout>
<RelativeLayout fill_parent>
<LinearLayout height="fill_parent" width="387dp">
RIGHT SCREEN
</LinearLayout>
<LinearLayout height="fill_parent" marginLeft="387dp" width="147dp">
LEFT SCREEN
</LinearLayout>
</RelativeLayout>
</LinearLayout>
