Is it possible to receive a signal over 315 MHz on an Android device?

Question

I want to make an android application that will receive basic data transmitted from a RF Link Transmitter (https://www.sparkfun.com/products/10535?). I want to know first off if it is possible to somehow control what frequency you can receive a signal on.

Generally, no. Android is an operating system. It is not hardware. Specifically, it is not a software-defined radio (SDR) receiver. In principle, Android could power a device that had SDR capabilities, but Android itself has nothing related to SDR, certainly at the SDK level. Or, Android could power a device that happens to have a suitable 315MHz receiver, but your general off-the-shelf Android device probably does not have such a receiver, and the OS does not have anything specific for that sort of receiver.
