Q:

Developing to all devices

Is there any way with the Android SDK to emulate a specific device ROM?  For example, could I launch an emulator that replicated the Verizon Droid Incredible, or the Sprint HTC Hero?

A:

There is not a way to say make my emulator be a Droid. However, you can create an avd with many of the features of the different phones: sdk versions, screen sizes, disk space, etc.  See avd documentation for details.  For most applications, as long as you test against a few different sdk levels and screen sizes you should be ok.
