Android get location on asynctask

I am using this code for fetching current location, this code is working fine but now need to put
this code on Asynctask class , I don't have any idea how can implement this code on Asynctask
Please help me How can do this
public class GetLoc implements LocationListener{
SharedPreferences preferences = null;
SharedPreferences.Editor editor = null;
Context context;
LocationManager locationManager ;
String provider;
double lati;
double logi;
ProgressDialog pd;
public static String state;
String zz;
public GetLoc(Context context)
{
this.context= context;
locationManager = (LocationManager)context.getSystemService(Context.LOCATION_SERVICE);
//Toast.makeText(context, "Location can't be retrieved", Toast.LENGTH_SHORT).show();
Criteria criteria = new Criteria();
// pd = ProgressDialog.show(context, "","Please wait... ");
// Getting the name of the provider that meets the criteria
provider = locationManager.getBestProvider(criteria, false);
if(provider!=null && !provider.equals("")){
// Get the location from the given provider
Location location = locationManager.getLastKnownLocation(provider);
locationManager.requestLocationUpdates(provider, 20000, 1, this);
if(location!=null)
onLocationChanged(location);
else
Toast.makeText(context, "Location can't be retrieved", Toast.LENGTH_SHORT);
}else{
Toast.makeText(context, "No Provider Found", Toast.LENGTH_SHORT);
}
}
#Override
public void onLocationChanged(Location location) {
// TODO Auto-generated method stub
if(location.getLatitude()>0 && location.getLongitude()>0)
{
lati=location.getLatitude();
logi=location.getLongitude();
state= getAddress(context, lati, logi);
}
// Toast.makeText(context, "No"+zz, Toast.LENGTH_SHORT).show();
// pd.dismiss();
}
#Override
public void onStatusChanged(String provider, int status, Bundle extras) {
// TODO Auto-generated method stub
}
#Override
public void onProviderEnabled(String provider) {
// TODO Auto-generated method stub
}
#Override

}
public String getAddress(Context ctx, double latitude, double longitude) {
StringBuilder result = new StringBuilder();
try {
Geocoder geocoder = new Geocoder(ctx, Locale.getDefault());
List<Address> addresses = geocoder.getFromLocation(latitude, longitude, 1);
if (addresses.size() > 0) {
Address address = addresses.get(0);
//String locality=address.getLocality();
//String city=address.getCountryName();
//String region_code=address.getCountryCode();
state= address.getAdminArea();
// zipcode=address.getPostalCode();
double lat =address.getLatitude();

// result.append(city+" "+ region_code+" ");
//result.append(zipcode);
}
} catch (IOException e) {
// Log.e("tag", e.getMessage());
}
return state;
}
}

Try this way:
#Override
protected void onPreExecute() {
mVeggsterLocationListener = new VeggsterLocationListener();
mLocationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
mLocationManager.requestLocationUpdates(
LocationManager.NETWORK_PROVIDER, 0, 0,
mVeggsterLocationListener);
progDailog = new ProgressDialog(FastMainActivity.this);
progDailog.setOnCancelListener(new OnCancelListener() {

FetchCordinates.this.cancel(true);
}
});
progDailog.setMessage("Loading...");

progDailog.show();
}
#Override
protected void onCancelled(){
System.out.println("Cancelled by user!");
progDialog.dismiss();
mLocationManager.removeUpdates(mVeggsterLocationListener);
}
#Override
protected void onPostExecute(String result) {
progDailog.dismiss();
Toast.makeText(FastMainActivity.this,
"LATITUDE :" + lati + " LONGITUDE :" + longi,

}
#Override

// TODO Auto-generated method stub
while (this.lati == 0.0) {
}
return null;
}

How to get location of android device by its android id

I am new in android and recently start learning about Android and I am trying to get location of any android device by its unique android id. By that I can track the approx or exact location either by GPS or network provider. In detail I mean to say that whenever i enter any Android id in my app i can get device location in my application. Thanks for your kind help.

Finally I am able to do with this code:
public class MyService extends Service implements LocationListener{

if you want to get location of any device who has your app in their mobile , you can get it ,
firstly in your app you can upload locations to your server with memberid(you can set it , unique for every device) for every x time(you can set it how many times you update the location).
And then you can check your db on your server which device in where.
(my advice you can use webservice to update db on your server)

set Timeout for GPS listening

I'm able to get location update from network provider but when it comes to gps it takes a lot of time for the data to be picked. I want to keep a particular time for which only the GPS listener will work and then move on to network provider after sometime. How to fix this issue ?
This is my code..
public void gpslocation()
{
final LocationManager locationManager = (LocationManager) this
.getSystemService(Context.LOCATION_SERVICE);
LocationListener locationListener = new LocationListener() {
public void onLocationChanged(Location location)
{
updateLocationForGeo(location);
//update(location);
// Called when a new location is found by the network location provider.
makeUseOfNewLocation(location);
}
private void makeUseOfNewLocation(Location location) {
// TODO Auto-generated method stub
}
public void onStatusChanged(String provider, int status,
Bundle extras) {
}
public void onProviderEnabled(String provider) {
System.out.println(provider+ "enabled provider");
}
public void onProviderDisabled(String provider) {
// TODO Auto-generated method stub
System.out.println(provider+ "disabled provider");
networklocation();
}
};
String locationProvider = LocationManager.GPS_PROVIDER;
locationManager.requestLocationUpdates(locationProvider, 10 * 1000, (float) 10.0,locationListener);
}
public void networklocation()
{

}
};
String timeProvider = LocationManager.NETWORK_PROVIDER;
locationManager.requestLocationUpdates(timeProvider, 1 * 1000, (float) 10.0, locationListener);
}
public void updateLocationForGeo(Location location){
System.out.println("location updated");
double dev_lat = location.getLatitude();

If you want to turn on GPS enabled automatically in your app, I'm afraid there is no way other than prompt the user.
You can achieve that easily with modifying onProviderDisabled() method in your LocationListener. The idea is to open a dialog asking user to turn on GPS:
public void onProviderDisabled(String arg0)
{
showDialog(CHOICE_GPS_ENABLE);
}
add in your activity:
protected final static int CHOICE_GPS_ENABLE = 1; //or any other number
#Override
protected Dialog onCreateDialog(int id)
{
Dialog dialog = null;
switch (id)
{
case CHOICE_GPS_ENABLE:
dialog = createGPSEnableDialog();
break;
default:
dialog = super.onCreateDialog(id);
break;
}
return dialog;
}
protected Dialog createGPSEnableDialog()
{
Dialog toReturnGPS;
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setMessage("You don't have GPS enabled. Go to Settings and enable GPS?");
builder.setTitle("GPS failed");
builder.setPositiveButton("Yes, enable GPS",
new DialogInterface.OnClickListener()
{
public void onClick(DialogInterface dialog, int which)
{
Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
startActivity(intent);
}
});
builder.setNegativeButton("No, quit application",
new DialogInterface.OnClickListener()
{
public void onClick(DialogInterface dialog, int which)
{
onDestroy();
}
});
toReturnGPS = builder.create();
return toReturnGPS;
}
Hope it helps.

i want GPS turn on automatically if my application running
how can i do this??
I don't think you can do anything beyond prompt the user to turn it on. So Im afraid you are going to be unable to make your application work how you'd like.

use
Location locationtest;
public void onLocationChanged(Location location) {
locationtest=location;
updateWithNewLocation(locationtest);
}
public void onProviderDisabled(String provider){
locationtest= null;
updateWithNewLocation(locationtest);
}
instead of
public void onProviderDisabled(String provider){
updateWithNewLocation(null);
}

Unable to toast latitude and longitude

Am working on an app, which toasts the latitude and longitude using LocationManager and LocationListener. On running the app, an error shows up saying "Sorry, Process system is not responding.". This happens when I supply the lat and long either manually from emulator control under DDMS or from command prompt using telnet.
Java Code:
public class LocationFinder extends Activity {
private LocationManager locManager;
private LocationListener locListener;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
locManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
locListener = new MyLocationListener();
locManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locListener);
}
private class MyLocationListener implements LocationListener{
#Override
public void onLocationChanged(Location loc) {
// TODO Auto-generated method stub
if(loc != null){
Toast.makeText(getBaseContext(), "Latitude: " + loc.getLatitude() + "Longitude: " + loc.getLongitude(), Toast.LENGTH_SHORT).show();
}
}
#Override
public void onProviderDisabled(String provider) {
// TODO Auto-generated method stub
}
#Override
public void onProviderEnabled(String provider) {
// TODO Auto-generated method stub
}
#Override
public void onStatusChanged(String provider, int status, Bundle extras) {
// TODO Auto-generated method stub
}
}
}
And I have set the following permissions in manifest.xml
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_GPS" />
<uses-permission android:name="android.permission.ACCESS_ASSISTED_GPS" />
The emulator is also hw.gps enabled.
I would like to know if there is anything wrong with my code.
Thanks

Check by using Log that you are getting Values for Latitude and longitude..
Then in Toast put this
Toast.makeText(LocationFinder.this, "Latitude: " + loc.getLatitude() + "Longitude: " + loc.getLongitude(), Toast.LENGTH_SHORT).show();
instead of
Toast.makeText(getBaseContext(), "Latitude: " + loc.getLatitude() + "Longitude: " + loc.getLongitude(), Toast.LENGTH_SHORT).show();
