With LAMW, you can't at the moment.
There is no implementation yet of "android.location.GpsStatus".

But you can ask the author for this feature !
In most cases, he is very willing to implement feature requests like
this.

Hi
this code dose not work ?!?

i change that to :
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
TamMain.myLocGpsStatusChanged(Sender: TObject;  countSatellites:
integer; gpsStatusEvent: TGpsStatusEvent);var  i: integer;begin  case
gpsStatusEvent of     gpsStarted: begin     
 jTextView2.Text:='gpsStarted'+#10+#13+       'countSatellites =
'+IntToStr(countSatellites);     end;     gpsStopped: begin     
 jTextView2.Text:='gpsStopped'+#10+#13+       'countSatellites =
'+IntToStr(countSatellites);     end;     gpsFirstFix: begin       
jTextView2.Text:=FloatToStr(myLoc.GetTimeToFirstFix())+#10+#13+      
'gpsFirstFix';     end;     gpsSatelliteStatus: begin     
 jTextView2.Text:='gpsStopped'+#10+#13+       'countSatellites =
'+IntToStr(countSatellites);       for i:= 0 to countSatellites-1 do 
    begin         jTextView1.Text:= (myLoc.GetSatelliteInfo(i));     
 end;     end;  end;end; 
but all time countSatellites = 0 ?!?

You may have to wait a lot more ... or even move to an open area ...
[I tested the code and it works!]

to better info fix here...
Code: [Select]gpsSatelliteStatus: begin
       jTextView2.Text:='gpsSatelliteStatus'+#10+#13+     //FIX HERE!
       'countSatellites = '+IntToStr(countSatellites);
       for i:= 0 to countSatellites-1 do
       begin
         jTextView1.Text:= (myLoc.GetSatelliteInfo(i));
       end;
     end;

Hi
the program find my position but no show number satellite ?!?

jTextView2.Text alternative show 'gpsStarted' and  'gpsStoped' but no
show show number satellite ?

----------------------------------------------------------------------

Please, first try demo "AppLocationDemo1"

You need:

1. Enable Wifi in your smartphone
2. Enable  gps in your smartphone
3. Run app
4. Click the first button "Try StartTracker"

and wait.... wait.... wait....
[here, in my house, I need go to an open area...]

----------------------------------------------------------------------
majid.ebru · 2017-02-28 09:40

i completely understand what you say.
i find my position whit my app.
.
.
also my WiFi is OFF.
but see attach please

----------------------------------------------------------------------
jmpessoa · 2017-02-28 17:01

Yes, when "gpsStarted"  we get countSatellites = 0 !
[that is right!]

wait until  "gpsSatelliteStatus",  so we will get  the real
countSatellites <> 0 !!!

[You need WIFI = ON!   Enable it!]

----------------------------------------------------------------------
majid.ebru · 2017-03-04 05:14

don't work again !!

i enable WiFi and google find my position but , don't show satellite
number??

value of gpsStatusEvent is only :  gpsStarted and gpsStopped
and never gpsFirstFix and gpsSatelliteStatus Event( or show) ?!?!

Quotevalue of gpsStatusEvent is only :  gpsStarted and gpsStopped
and never gpsFirstFix and gpsSatelliteStatus Event( or show) ?!?!

Well, You need wait until value of gpsStatusEvent = gpsSatelliteStatus
[or gpsFirstFix ] but In your area this does not seem easy... here in
my house I always need to go to an open area [backyard... or  street
...]
