How to detect whether GPS signal is weak or high ?

Question

Hi guys,

How to detect GPS signal strength such as low (weak) or high ?

is there an API class ?

Thanks in advance.

Answer 1

GpsStatus. getSatellites();
//for each of those do 
GpsSatelite. getSnr();
//that ruturns the signal to noise ratio
//use with
GpsStatus.Listener

Heres the api docs: Location manager - GpsStatus - GpsSatelite

Answer 2

The getAccuracy() method of the Location object returned by onLocationChanged provides a good indication of how good the "fix" is.
