comment Distance calculation : Integrating incremental gps data
I just added raw nmea sample output, very new to nmea parsing, can you have a look and tell me is that enough to determine if the device is stationary ? ( I think the device has not yet acquired a valid fix )

The data is been calculated inside android internally and this is all I get from it. Android is handling the calculations. I sense it is better to calculate them myself using raw NMEA data ?

comment Distance calculation : Integrating incremental gps data
Great answer !!.. however let me tell you why I am facing a overestimate.. Typically, when in a traffic signal / just plainly stopped on road.. the android api tells me the new lat long pair when there is a displacement of minimum 5 meters.. The problem is the api informs me of even the "drifted" lat long to be 5m away and hence I increment the odometer value which keeps accumulating errors because device did not move.. Hence if the device is stationary it keeps accumulating this error.. I can send you actual gps data for you to have a look..

@mhoran_psprep I needed an algorithm to incorporate altitude. ALso the altitude data fluctuates and is not very accurate.
