GnssStatusCompat

public abstract class GnssStatusCompat
extends Object

java.lang.Object
   ↳ androidx.core.location.GnssStatusCompat

GnssStatus representation that works across all Android versions. See GnssStatus and GpsStatus.

Note: When used to wrap GpsStatus, the best performance can be obtained by using a monotonically increasing satelliteIndex parameter (for instance, by using a loop from 0 to getSatelliteCount()). Random access is supported but performance may suffer.
