This flow is will report your position via SMS when a key phrase is received via SMS. It is intended as a safety system so that your position can be found in the event of an emergency without draining battery power from constant use of the GPS receiver.
The flow is activated when a particular key word is received. It will then turn on the GPS, acquire your location, turn the GPS back off and then send your location, speed, heading and altitude back to the sender via SMS. Your location is reported in a link to Google maps that can be used as a point to navigate to.
Version 2 adds battery saving options by turning off WiFi and Data Sync. Another option does the same but turns on Bluetooth if needed.
