Subject: [PATCH 2/2] Persist pedometer data on low memory callbacks

If android is encountering a low memory situation, save the
current pedometer counts. It is possible for Android to kill
the app and restart it later when memory is available.
Unless the pedometer values are saved, they will be lost.
