Is there a working .apk for android(google voice)

I have tried to see if there was a way that I can use google voice on the Motorola Droid, but all the .apk files don’t work. Says that there is a “problem parsing the package”. I know that it works for froyo and all that, but is there a way to fix this problem? Or is it just that it doesn’t work for the Droid?

Any suggestion, links, etc would be appreciated.
