To add to Andrei's answer.

To help out with your burden you could always use: http://members.ping.de/~sven/dpi.html to calculate the dpi.

And wikipedia lists a lot of different devices so it's only for you to go through them and calculate. Of course if it's not stated somewhere else like sven's calculator. But first read through http://developer.android.com/guide/practices/screens_support.html

You should read http://developer.android.com/guide/practices/screens_support.html

It will answer to many your questions.

Google Nexus One and Motorola Droid have hdpi (in practice, all phones, not tablets, with 480x800 and higher resolutions, have hdpi, 320x480 phones - mdpi)
