Required application feature

When this function is used, an application feature is declared in the application generation wizard.
Required feature: Geolocation
This feature allows the applications to access the geolocation features found on the device or on the computer.

[ + ] This example explains how to perform proximity searches with geolocation :
- search around me
- search in a city, at a given address, or close to a specific address.
The results are displayed in a looper and in a map with markers.
Android GPS Android (WINDEV Mobile): Android GPS
[ + ] This example presents the use of the GPS functions of WLanguage in an Android application.
It is used to retrieve at regular interval:
- The latitude
- The longitude
- The altitude
- The speed
- The direction

Example 01:
#####################################################

Procedure GPS_VerificaStatus()

Retorno is string = ""

GloLatitude , GloLongitude is real = 0

GPSInitParameter(gpsSatellite,gpsPrecisionHigh)

// Recuperação da posição
Retorno is geoPosition = GPSGetPosition() // 2000 = Intervalo máxo,p de 20 segundos

GloLatitude = NumToString(Retorno..Latitude,"+-10.6f")
GloLongitude = NumToString(Retorno..Longitude,"+-10.6f")

Retorno = GloLatitude +"; "+ GloLongitude

IF GloLatitude = 0 AND GloLongitude = 0 OR GloLatitude = null AND GloLongitude = null
ToastDisplay("GPS Desligado!!!")
END

RESULT(Retorno )

---x---



Example 02:
#####################################################

//Java GPS_On

import android.app.Activity;
import java.lang.*;
import android.util.*;
import java.lang.Exception;
import android.util.Log;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;

PUBLIC static void GPS_On()
{
Intent intent = new Intent("android.location.GPS_ENABLED_CHANGE");
intent.putExtra("enabled", True);
getActiviteEnCours().sendBroadcast(intent);
}

---x---

//Java GPS_Off

import android.app.Activity;
import java.lang.*;
import android.util.*;
import java.lang.Exception;
import android.util.Log;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;

PUBLIC static void GPS_Off()
{
Intent intent = new Intent("android.location.GPS_ENABLED_CHANGE");
intent.putExtra("enabled", False);
getActiviteEnCours().sendBroadcast(intent);
}


---x---

OBS.:
You must enable these options in the Android Manifest XML Windev Mobile

A) Android.Permission.WRITE_SECURE_SETTINGS

B) Android.Permission.WRITE_SETTINGS

Example 03
#####################################################
Another way to test whether this off GPS:

// GLOBAL
GloGpsAtivado is boolean = False

//Open Window
Procedure GPS_Inicializar()

GPSInitParameter(gpsSatellite,gpsPrecisionHigh +gpsSpeed)

IF GPSStatus() <> gpsEnabled THEN

Popup("Para melhorar a precisão da sua localização, ative o seu GPS","L")

gloStatusGps = False

ELSE
ChangeGPSStatus(GPSStatus())
END

GPSStatus(ChangeGPSStatus)

---x---

//Procedure Global

Procedure ChangeGPSStatus(nStatus)
IF gnCurrentStatus = nStatus THEN
RETURN
END

gnCurrentStatus = nStatus

IF nStatus = gpsEnabled OR nStatus = gpsAvailable THEN

GPSFollowMovement(GetPosition,300)

END

SWITCH nStatus
CASE gpsEnabled
GloGpsAtivado = True // <------------- Ligado
CASE gpsDisabled
GloGpsAtivado = False // <------------- Desligado
gloStatusGps = False
CASE gpsOffService
CASE gpsUnavailable
CASE gpsAvailable
END
