Question

I read a topic about multiple screen support, but I don’t understand why I need a different picture for every screen size if I can stretch image by setting

        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:background="@drawable/bk"

for every screen.

Answer 1

You don’t have to have a different image for each screen size. You certainly can just use fill_parent and just use the same image. The only issue is that it usually won’t look as good. In fact, in some cases it will look absolutely terrible. Assuming that you’re fine with your image being stretched though, you can just use one image.
