Integrate GPS in JavafxPorts

Question

I have a Javafx application which is to be deployed in Android. My app needs to get the latitude and longitude but I dont know how to implement them. Can someone give me a code sample on how to do it in JavaFX?

UPDATED:

package com.gpstracker;

import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.geometry.Insets;
import javafx.geometry.Rectangle2D;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.TextField;
import javafx.scene.layout.VBox;
import javafx.stage.Screen;
import javafx.stage.Stage;

public class GPSTracker extends Application {

    @Override
    public void start(Stage stage) {
        TextField t1 = new TextField();

        TextField t2 = new TextField();

        Button button = new Button("Show Location");
        button.setOnAction(new EventHandler<ActionEvent>(){
            @Override
            public void handle(ActionEvent event) {
                PositionService positionService = PlatformFactory.getPlatform().getPositionService();
                Position position = positionService.getPosition();
            }
        });

        VBox root = new VBox(20);
        root.setPadding(new Insets(20));
        root.getChildren().addAll(t1, t2, button);

        Rectangle2D visualBounds = Screen.getPrimary().getVisualBounds();
        Scene scene = new Scene(root, visualBounds.getWidth(), visualBounds.getHeight());

        stage.setScene(scene);
        stage.show();
    }

}

Gloun cant seem to find a class call PositionService and Position.

Answer 1

With Gluon Mobile, the current position of a device can be tracked with the PositionService . A sample code snippet:

PositionService positionService = PlatformFactory.getPlatform().getPositionService();
Position position = positionService.getPosition();
System.out.println("Current GPS position: " + position.getLatitude() + "," + position.getLongitude());

Answer 2

This can be achieved via the Gluon Mobile library. http://gluonhq.com/products/mobile/

Answer 3

To use PositionService , mentioned by Joeri , you have to add a dependency to Gluon open source charm-down library. Here is a sample configuration for your build.gradle :

dependencies {
    compile 'com.gluonhq:charm-down-common:2.0.0';
    desktopRuntime 'com.gluonhq:charm-down-desktop:2.0.0';
    androidRuntime 'com.gluonhq:charm-down-android:2.0.0';
    iosRuntime 'com.gluonhq:charm-down-ios:2.0.0';
}
