Public methods
addMslAltitudeToLocation
fun addMslAltitudeToLocation(
context: Context,
location: Location
): Unit
Adds a Mean Sea Level altitude to the location
. In addition, adds a Mean Sea Level altitude accuracy if the location
has a finite and non-negative vertical accuracy; otherwise, does not add a corresponding accuracy.
Must be called off the main thread as data may be loaded from raw assets.
This method may take several seconds to complete, so it should only be called from a worker thread.

context |
Context: This value cannot be null . |
location |
Location: This value cannot be null . |
Exceptions | |
---|---|
java.io.IOException |
if an I/O error occurs when loading data from raw assets. |
java.lang.IllegalArgumentException |
if the location has an invalid latitude, longitude, or altitude above WGS84. Specifically, the latitude must be between -90 and 90 (both inclusive), the longitude must be between -180 and 180 (both inclusive), and the altitude above WGS84 must be finite. |
