I'm working on adding a calibration feature to an accelerometer-driven game. For the calibration, I need a single value from the accelerometer. Should I register a listener, get the first value it gives me, and unregister it, or is there a better way to get just one value?

This should help:

You simply get sensors which you are interested in and read their values.

I can get a `Sensor` object, but how can I get a reading?http://developer.android.com/reference/android/hardware/Sensor.html

getResolution() or getPower() method.

Neither of those return the sensor's value. getPower returns the number of milliamps the sensor is using and getResolution returns the sensors accuracy.

Basically there is no way to do get a single value as far as I can tell. What I ended up doing is putting in a variable called lastAccelValue and registering my Activity to listen for accelerometer updates at the slowest possible speed. Each new accelerometer value is stored to lastAccelValue.
