Ok so what you mean is you have a website already written. Then using the browser application in Droid devices of different screen sizes to view your website the alignment may go hay-wire is it ?
You are asking if there is any meta tag need to be written on your website so the Droid browser application can know how to re-size your web pages display correctly ?
From Google Maps API website, it says iPhone devices respect <meta name="viewport" content="initial-scale=1.0, user-scalable=no" />
But for Android it seems you need to write an Android application specifically. Refer to http://code.google.com/apis/maps/articles/android_v3.html
I maybe wrong so please research other websites on display web-pages on Droid browser application.
