geolocation - Android.Location.toString() interpretation of `et` -

-

when use .tostring() method on location object have results this:

location[gps 01.234567,12.234567           acc=14           et=+2d23h36m34s870ms           alt=123.0           vel=0.0           {bundle[mparcelleddata.datasize=40]}          ]

(i added newlines better readability)

i guess (after research here: link):

  • acc=14 accurracy in meters
  • vel=0 velocity in meters/second
  • alt=123 altitude above wgs reference ellipsoid in meters

but et=+2d23h36m34s870ms?

according javadocs:

/** * return time of fix, in elapsed real-time since system boot. * *

this value can reliably compared * {@link android.os.systemclock#elapsedrealtimenanos}, * calculate age of fix , compare location fixes. * reliable because elapsed real-time guaranteed monotonic * each system boot , continues increment when system * in deep sleep (unlike {@link #gettime}. * *

all locations generated {@link locationmanager} * guaranteed have valid elapsed real-time. * * @return elapsed real-time of fix, in nanoseconds since system boot. */

public long getelapsedrealtimenanos() {     return melapsedrealtimenanos; }

tostring code relevant et

if (melapsedrealtimenanos == 0) {     s.append(" et=?!?"); } else {     s.append(" et=");     timeutils.formatduration(melapsedrealtimenanos / 1000000l, s); }

and way meaning of how long has been since location last updated
