I want to monitor the velocity of a phone. I can do this by looking at accelerometer data over the last 30 seconds, saving about one sample every 0.1 seconds (300 samples) and applying a sliding filter to the data. If I create a service to do this, what's the best way to preserve the state of the filter (600 doubles) between an onDestroy and a subsequent onCreate? I can set up an SQLite table to hold the values but that's a lot of extra coding and processing overhead. Is there a better way?
