Android Benchmark test and feature listing!

DROIDparade is a database of mobile phones and other devices running the Android open source software stack. Although these devices expose basically the same Android API, there are subtle differences regarding screen resolution, memory sizes, available sensors, and speed. This is important information for testing purposes from an ap- plication developers point of view, who naturally cannot own all the devices available on the market. DROIDparade accumulates this information and makes it available to the Android developer community. It receives 'live' data from the DROIDinfo application that is also publicly available and can be run on the different devices by their owners. DROIDinfo is also useful as a standalone testing tool. It quickly provides developers with an overview of the hardware, software, and speed of the device they have in their hands.
