Priceline put its Hotel Negotiator app, available for the iPhone since 2009, on the Android platform.
The free app can be downloaded from the Android Market.
Both apps enable users to bid on hotel rooms or book them at published prices up until 11 p.m. on the night of the desired stay, Priceline says.
The Android and iPhone apps have similar functionality.
The chief difference between the two for now is that the iPhone app, which also works on the iPod touch and iPad, also includes the ability to book rental cars, and the Android app doesn't have that capability, although Priceline says it's coming.
