Android: GpsLocation class

[Gogeta70]

Hey dudes. I've been developing an app for my employer and one of the functions is to provide a GPS location when an employee clocks in using the app. I wrote a class to provide the GPS location in simple manner, so i thought i would share it.

Code: Select all

package com.example.sei;

import android.content.Context;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;

public class GpsLocation {
	
	public LocationManager lManager = null;
	public boolean GpsEnabled, NetLocEnabled;
	
	double Latitude, Longitude;
	float Accuracy;
	
	public MyActivity callback;
	
	GpsLocation(){}
	
	public boolean StartGPS(Context c)
	{
		
		lManager = (LocationManager) c.getSystemService(Context.LOCATION_SERVICE);
		
		Accuracy = 9999;
		
		if(lManager == null)
			return false;
		
		if(!IsLocationAvailable(c))
			return false;
		
		if(!GpsEnabled && !NetLocEnabled)
			return false;
		
		if(GpsEnabled)
		{
			lManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locationListener);
		}
		
		if(NetLocEnabled)
		{
			lManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, locationListener);
		}
		
		callback = (MyActivity) c;
		
		return true;
	}
	
	public boolean IsLocationAvailable(Context c)
	{
		GpsEnabled = false;
		NetLocEnabled = false;
		
		if(lManager == null)
			lManager = (LocationManager) c.getSystemService(Context.LOCATION_SERVICE);
		
		try {
			
			if(lManager.isProviderEnabled(LocationManager.GPS_PROVIDER))
				GpsEnabled = true;
			
			if(lManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER))
				NetLocEnabled = true;
			
		} catch (Exception e) {
			
			e.printStackTrace();
		}
		
		if(GpsEnabled || NetLocEnabled)
			return true;
		
		return false;
	}
	
	LocationListener locationListener = new LocationListener()
	{	
		public void onLocationChanged(Location location)
	    {
	    	
			if(location.getAccuracy() <= Accuracy)
			{
				Accuracy = location.getAccuracy();
	    		Latitude = location.getLatitude();
	    		Longitude = location.getLongitude();
	    		
	    		callback.GpsUpdate(Accuracy, Longitude, Latitude);
			}
	    }

		@Override
		public void onProviderDisabled(String provider) {}

		@Override
		public void onProviderEnabled(String provider) {}

		@Override
		public void onStatusChanged(String provider, int status, Bundle extras) {}
	};
	
	public void StopGPS()
	{
		lManager.removeUpdates(locationListener);
	}
	
}

// In your activity, create the GpsLocation class and create this method:

public void GpsUpdate(float Accuracy, double Longitude, double Latitude)
{
}

Anyway, just thought i'd share... i'm not too great at java yet, so there is probably a better way to do it though. ^_^

um, wait...you mean you can track people with it via GPS?

Very nice man

I Did some GPS Location stuff but in javascript. Will see if I can post the code

Speak soon!

The class just provides an interface to the GPS service that already exists in the phone. You could use it to track people, but you would have to make your own android app to do so.

I'm using it to track the location of our employees when they clock in and out using the app.
