android: how to get updated location with gps

I'm making an app to send current location of user via sms after fixed time but it always send the same coordinates. I read lot of links but I don't know where is the mistake kindly tell me what is the problem in my code you can edit the code as u like
public class AlarmReceiver extends BroadcastReceiver implements LocationListener {
long time = 600* 1000;
long distance = 10;
boolean isGPSEnabled = false;
boolean isNetworkEnabled = false;
Location location;
String device_id;
String phoneNo = "+923362243969";
#SuppressLint("NewApi")
#Override
public void onReceive(Context context, Intent intent) {
System.out.println("alarm receiver....");
Intent service = new Intent(context, MyService.class);
context.startService(service);
//Start App On device restart
if ("android.intent.action.BOOT_COMPLETED".equals(intent.getAction())) {
Intent App = new Intent(context, MainActivity.class);
App.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(App);
}
TelephonyManager tm = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
device_id = tm.getDeviceId(); // returns IMEI number
try {
LocationManager locationManager = (LocationManager) context.getSystemService(context.LOCATION_SERVICE);
// getting GPS status
isGPSEnabled = locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER);
// getting network status
isNetworkEnabled = locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
if (isGPSEnabled) {
if (location == null) {
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,time,distance, this);
Log.d("GPS Enabled", "GPS Enabled");
if (locationManager != null) {
location = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
if (location != null) {
location.getLatitude();
location.getLongitude();
String Text = " From GPS: Latitude = " + location.getLatitude() +" Longitude = " + location.getLongitude() + " Device Id: " + device_id;
SmsManager smsManager = SmsManager.getDefault();
smsManager.sendTextMessage(phoneNo, null, Text, null, null);
Log.i("Send SMS", "");
this.abortBroadcast();
}
}
}
}
else {
if (isNetworkEnabled) {
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, time,distance, this);
Log.d("Network", "Network");
if (locationManager != null) {
location = locationManager .getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
if (location != null) {
location.getLatitude();
location.getLongitude();
String Text = " From Network: Latitude = " + location.getLatitude() +" Longitude = " + location.getLongitude() + " Device Id: " + device_id;
SmsManager smsManager = SmsManager.getDefault();
smsManager.sendTextMessage(phoneNo, null, Text, null, null);
Log.i("Send SMS", "");
this.abortBroadcast();
}
}
}
}
} catch (Exception e) {
Toast.makeText(context, "no connection", Toast.LENGTH_LONG).show();

}
}
#Override
public void onLocationChanged(Location location) {
// TODO Auto-generated method stub
}
#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
}
}

This is where you need to get the location. Take Longitude and Latitude variables as public members and updated them in the below event.
double Latitude, Longitude;
#Override
public void onLocationChanged(Location location) {
Longitude = location.getLongitude();
Latitude = location.getLatitude();
}
And while sending a SMS, put Longitude and Latitude variables in place of location.

auto send sms when gps location is available

i'm developing an app to send user location via sms after a fixed time and if the phone restarts the app should starts automatically in the background without any launcher activity. I have quiet accomplished my task I'm only facing problem in getting location, as gps takes some time and app gets crash when it does not find any location.
here is my code of main Activity
public class MainActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
startLocationTracking();
}
private void startLocationTracking()
{
AlarmManager am = (AlarmManager)getSystemService(ALARM_SERVICE);
Intent alarmintent1 = new Intent(MainActivity.this, AlarmReceiver.class);
PendingIntent sender1=PendingIntent.getBroadcast(MainActivity.this, 100, alarmintent1, PendingIntent.FLAG_UPDATE_CURRENT | Intent.FILL_IN_DATA);
try {
am.cancel(sender1);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
System.out.println("exjfkd"+e);
}
Calendar cal = Calendar.getInstance();
cal.add(Calendar.MINUTE,10);
am.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), 1000*600, sender1);
System.out.println("set timer");
}
}
public class AlarmReceiver extends BroadcastReceiver{
long time = 600* 1000;
long distance = 10;
#SuppressLint("NewApi")
#Override
public void onReceive(final Context context, Intent intent) {
System.out.println("alarm receiver....");
Intent service = new Intent(context, MyService.class);
context.startService(service);
//Start App On Boot Start Up
if ("android.intent.action.BOOT_COMPLETED".equals(intent.getAction())) {
Intent App = new Intent(context, MainActivity.class);
App.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(App);
}
try{
LocationManager locationManager = (LocationManager)context
.getSystemService(Context.LOCATION_SERVICE);
Criteria criteria = new Criteria();
String provider = locationManager.getBestProvider(criteria, true);
locationManager.requestLocationUpdates(provider, time,
distance, locationListener);
Location location = locationManager.getLastKnownLocation(provider);
TelephonyManager tm = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
String device_id = tm.getDeviceId(); // returns IMEI number
String phoneNo = "+923362243969";
String Text = "Latitude = " + location.getLatitude() +" Longitude = " + location.getLongitude() + " Device Id: " + device_id;
SmsManager smsManager = SmsManager.getDefault();
smsManager.sendTextMessage(phoneNo, null, Text, null, null);
Log.i("Send SMS", "");
}
catch (Exception e) {
e.printStackTrace();
}
this.abortBroadcast();
}
LocationListener locationListener = new LocationListener() {
#Override
public void onStatusChanged(String provider, int status, Bundle extras) {
}
#Override
public void onProviderEnabled(String provider) {
}
#Override
public void onProviderDisabled(String provider) {
}
#Override
public void onLocationChanged(Location location) {
}
};
}
i'm little confuse in logic I want my app to send sms when gps coordinates are available. and if gps in disabled on the phone it if network is available on the phone it should get the location through network and send it through the network.

EDIT
Your app is crashing since for the first time after reboot GPS/network won't have the lastknowlocation since
Location location = locationManager.getLastKnownLocation(provider);
In this line you will be receiving location as null.
String Text = "Latitude = " + location.getLatitude() +" Longitude = " + location.getLongitude() + " Device Id: " + device_id;
and in this line you will get the null pointer exception since location.getLatitude() is not posible.
so before this code try to check location!=null.
if(location!=null){
String Text = "Latitude = " + location.getLatitude() +" Longitude = " + location.getLongitude() + " Device Id: " + device_id;
}
Use this method to know the status of GPS availablity
public boolean isgpsavailable(Activity activity) {
LocationManager locationManager = (LocationManager) activity.getSystemService(Context.LOCATION_SERVICE);
boolean result = locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER);
return result;
}
Then put your code into a if(isgpsavailable(this)){...} Statement

You can send SMS with the android.telephony package. You can see how add to your project here: How do I add ITelephony.aidl to eclipse?
Something like this permit you send a textSMS:
SmsManager sms = SmsManager.getDefault();
sms.sendTextMessage(phoneNumber, scAddress, texto, null, null);
Hope it helps you!!

How can I start Android service separately?

Here what I need, how can I start Android service separately?
I got service running from background (Preference.Class),
public void startService(){
Intent intent;
intent = new Intent(getBaseContext(), ForegroundService.class);
startService(intent);
intent = new Intent(getBaseContext(), PostMobileHistory.class);
startService(intent);
intent = new Intent(getBaseContext(), PostLocation.class);
startService(intent);
sharedPreferences.edit().putBoolean("serviceStatus", true).commit();
}
and start the Location Manager which run in service after from the BroadcastReceiver, but why the previous service gone, and just only Lcation Manager left?
public class LocationManager extends Service implements LocationListener{
private android.location.LocationManager locationManager;
private String previousProvider = "gps";
private float previousAccuracy = 100;
public String mobileHistory_GUID = null;
Context context = this;
#Override
public void onCreate() {
SharedPreferences sharedPreferences = context.getSharedPreferences("mobileHistory", Context.MODE_PRIVATE);
mobileHistory_GUID = sharedPreferences.getString("GUID", "DEFAULT");
Log.i("SP Mobile History GUID", mobileHistory_GUID);
startTracking();
}
public void onDestroy(){
stopTracking();
}
#Override
public IBinder onBind(Intent intent) {
return null;
}
public void stopTracking(){
if(locationManager != null){
locationManager.removeUpdates(this);
Log.i("Location Manager", "Tracking stopped");
}
}
public void startTracking() {
//Get the location manager
locationManager = (android.location.LocationManager) getSystemService(Context.LOCATION_SERVICE);
boolean isGPSEnabled = locationManager.isProviderEnabled(android.location.LocationManager.GPS_PROVIDER);
boolean isNetworkEnabled = locationManager.isProviderEnabled(android.location.LocationManager.NETWORK_PROVIDER);
if (!isGPSEnabled && !isNetworkEnabled) {
Log.i("Provider Status", "No provider");
}
else {
if (isNetworkEnabled) {
String locationProvider = android.location.LocationManager.NETWORK_PROVIDER;
Log.i("Provider Status", "Network enabled");
// Register the listener with the Location Manager to receive location updates
locationManager.requestLocationUpdates(locationProvider, MIN_TIME_BW_UPDATES, MIN_DISTANCE_CHANGE_FOR_UPDATES, this);
}
if (isGPSEnabled) {
String locationProvider = android.location.LocationManager.GPS_PROVIDER;
Log.i("Provider Status", "GPS enabled");
// Register the listener with the Location Manager to receive location updates
locationManager.requestLocationUpdates(locationProvider, MIN_TIME_BW_UPDATES, MIN_DISTANCE_CHANGE_FOR_UPDATES, this);
}
}
if(locationManager != null){
Log.i("Location Manager", "Tracking started");
}
}
public void onLocationChanged(Location location) {
SharedPreferences sharedPreferences = context.getSharedPreferences("mobileHistory", Context.MODE_PRIVATE);
String mobileHistory_GUID = sharedPreferences.getString("GUID", "DEFAULT");
String location_GUID = String.valueOf(UUID.randomUUID());
if (location != null) {
String latitude = valueOf(location.getLatitude());
String longitude = valueOf(location.getLongitude());
String altitude = valueOf(location.getAltitude());
String accuracy = valueOf(location.getAccuracy());
String speed = valueOf(location.getSpeed());
String provider = location.getProvider();
float floatAccuracy = Float.valueOf(accuracy);
if(floatAccuracy <= 20 && provider.equals("gps")){
Arrays.setLocationArrayList(new Model_Location(location_GUID, mobileHistory_GUID, provider, latitude, longitude, altitude, accuracy, speed));
Log.i("Location", "GPS");
Log.i("Location", "<= 20");
Log.i("Location", latitude + " " + longitude + " " + altitude + " " + accuracy + " " + speed);
previousProvider = provider;
previousAccuracy = floatAccuracy;
}
else if(floatAccuracy > 20 && provider.equals("gps")){
previousProvider = provider;
previousAccuracy = floatAccuracy;
}
else if(floatAccuracy > 20 && floatAccuracy <= 100 && provider.equals("network")){
if(previousAccuracy > 20 && previousProvider.equals("gps")){
Arrays.setLocationArrayList(new Model_Location(location_GUID, mobileHistory_GUID, provider, latitude, longitude, altitude, accuracy, speed));
Log.i("Location", "Network");
Log.i("Location", ">= 20 && <= 50");
Log.i("Location", latitude + " " + longitude + " " + altitude + " " + accuracy + " " + speed);
}
}
else{
Log.i("Location", latitude + " " + longitude + " " + altitude + " " + accuracy + " " + speed);
}
}
}
public void onProviderDisabled(String provider) {
}
public void onProviderEnabled(String provider) {
}
public void onStatusChanged(String provider, int status, Bundle extras) {
}
}

The problem solve, I shouldn't put function in the onCreate() on service, moved to onStartCommand() and its work perfectly well...

My GPS provider is enabled but I get null location nonetheless

I'm using this code to get the geo-position of the user
public Location getLocation() {
Location location = null;
double lat;
double lng;
try {
LocationManager mLocationManager = (LocationManager) con.getSystemService(LOCATION_SERVICE);
// getting GPS status
boolean isGPSEnabled = mLocationManager.isProviderEnabled(LocationManager.GPS_PROVIDER);
// getting network status
boolean isNetworkEnabled = mLocationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
if (!isGPSEnabled && !isNetworkEnabled) {
Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
startActivity(intent);
} else {
// First get location from Network Provider
if (isNetworkEnabled) {
mLocationManager.requestLocationUpdates( LocationManager.NETWORK_PROVIDER, 0, 0, this);
Log.d("Network", "Network");
if (mLocationManager != null) {
location = mLocationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
if (location != null) {
lat = location.getLatitude();
lng = location.getLongitude();
System.out.println(lat);
}
}
}
//get the location by gps
if (isGPSEnabled) {
mLocationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,0,0, this);
Log.d("GPS Enabled", "GPS Enabled");
if (mLocationManager != null) {
location = mLocationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
if (location != null) {
lat = location.getLatitude();
lng = location.getLongitude();
System.out.println(lat);
}
}
}
}
} catch (Exception e) {
e.printStackTrace();
}
return location;
}
An this is what I get:
Network
39.68967
Gps Enabled
(nothing)
I can't understand the reason why Gps is enabled and I still can't get the coordinates from the gps provider

I just finished creating a sample project for understanding the usage of Location Services. I am just posting my code, feel free to use it for your need and understanding the working of Location Services.

Cannot get current location coordinates

I want to get current longitude and latitude as int
So I use this code
locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0,
0, this);
Location location = locationManager
.getLastKnownLocation(LocationManager.GPS_PROVIDER);
try {
gps_enabled = locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER);
} catch (Exception ex) {
}
try {
network_enabled = locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
} catch (Exception ex) {
}
// don't start listeners if no provider is enabled
if (!gps_enabled && !network_enabled) {
....Notify
}
if (gps_enabled) {
if (location != null) {
longitude =(int) (location.getLongitude()*1e6);
latitude = (int) (location.getLatitude()*1e6);
String accuracy = "Accuracy: " + location.getAccuracy();
}
}
if (network_enabled) {
if (location != null) {
longitude =(int) (location.getLongitude()*1e6);
latitude = (int) (location.getLatitude()*1e6);
String accuracy = "Accuracy: " + location.getAccuracy();
}
}
locationManager.removeUpdates(this);
Unfortunately longitude and latitude are always null.
I have all permission needed in the manifest.
How can I fix this issue?

Well this is what i use for location listener
import android.content.Context;
import android.location.Criteria;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;
public class LocationUtils implements LocationListener{
Context context;
private String provider;
private LocationManager locationManager;
private String latitude="no value";
private String longitude="no value";
public LocationUtils(Context context) {
this.context=context;
// Get the location manager
locationManager = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);
// Define the criteria how to select the locatioin provider -> use
// default
latitude="no value";
longitude="no value";
Criteria criteria = new Criteria();
provider = locationManager.getBestProvider(criteria, false);
Location location = locationManager.getLastKnownLocation(provider);
// Initialize the location fields
if (location != null) {
/*Toast.makeText(context, "Provider " + provider + " has been selected.",
Toast.LENGTH_SHORT).show();*/
// System.out.println("Provider " + provider + " has been selected.");
onLocationChanged(location);
} else {
/*Toast.makeText(context, "Location not available",
Toast.LENGTH_SHORT).show();*/
}
}
#Override
public void onLocationChanged(Location location) {
double lat = (double) (location.getLatitude());
double lng = (double) (location.getLongitude());
latitude = lat + "";
longitude = lng + "";
/* Toast.makeText(context, " lat: "+lat +" Long:"+lng,
Toast.LENGTH_SHORT).show(); */
}
#Override
public void onProviderDisabled(String provider) {
//Toast.makeText(context, "Disabled provider " + provider,
// Toast.LENGTH_SHORT).show();
}
#Override
public void onProviderEnabled(String provider) {
//Toast.makeText(context, "Enabled new provider " + provider,
// Toast.LENGTH_SHORT).show();
}
#Override
public void onStatusChanged(String provider, int status, Bundle extras) {
// TODO Auto-generated method stub
}
public String getLatitude() {
return latitude;
}
public String getLongitude() {
return longitude;
}
}
Now in your activity u can get
LocationUtils appLocationManager = new LocationUtils(getContext());
String latitude = appLocationManager.getLatitude();
String longitude = appLocationManager.getLongitude();
Also add
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"></uses-permission>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"></uses-permission>
in your manifest file

First check the GPS enabled in your device.
Check all the permissions included in the manifest
You are fetching the last known location using the GPS provider so remove that line and fetch the location individually for both the provider(There should be possible that your GPS is not available at that time so you did not get the location and you are fetching the last known location using the GPS so it can be null and if location will be null then it will not goes inside the conditions like if(network_enabled) and if(gps_enabled).).
In short check the Last known location of GPS if it is null then try to get the location using the Location provider and use that location.

hey you can make the service and use this code to get altitude and latitude and decode this using class

Try This code
double longitude,latitude;
int lon,lat;
getcurrentloc.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
if(!locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER)){
Toast.makeText(GpsLocationFinder.this, "Enable Your GPS", Toast.LENGTH_LONG).show();
}else{
LocationResult locationResult=new LocationResult() {
#Override
public void gotLocation(Location location) {
// TODO Auto-generated method stub
longitude=location.getLongitude();
latitude=location.getLatitude();
lon=(int)longitude;
lat=(int)latitude;
Toast.makeText(GpsLocationFinder.this, "Current Longitude"+longitude+" Current Latitude"+latitude,Toast.LENGTH_LONG).show();
}
};
MyLocation myLocation = new MyLocation();
myLocation.getLocation(GpsLocationFinder.this, locationResult);
}
}
});
And the MyLocation Class is Below
public class MyLocation {
Timer timer1;
LocationManager lm;
LocationResult locationResult;
boolean gps_enabled=false;
boolean network_enabled=false;
double longitude,latitude;
public boolean getLocation(Context context, LocationResult result)
{
//I use LocationResult callback class to pass location value from MyLocation to user code.
//Log.e("GPS DISTANCE","GPS Enabled");
locationResult=result;
if(lm==null)
lm = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);
//exceptions will be thrown if provider is not permitted.
//don't start listeners if no provider is enabled
//try{
try{
gps_enabled=lm.isProviderEnabled(LocationManager.GPS_PROVIDER);
}catch(Exception ex){
}
try{
network_enabled=lm.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
}catch(Exception ex){
}
if(!gps_enabled && !network_enabled){
return false;
}
if(gps_enabled){
lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 100, 100, locationListenerGps);
}
if(network_enabled)
lm.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, locationListenerNetwork);
timer1=new Timer();
timer1.schedule(new GetLastLocation(), 30000);
return true;
}
LocationListener locationListenerGps = new LocationListener() {
public void onLocationChanged(Location location) {
timer1.cancel();
locationResult.gotLocation(location);
lm.removeUpdates(this);
lm.removeUpdates(locationListenerNetwork);
}
public void onProviderDisabled(String provider) {}
public void onProviderEnabled(String provider) {}
public void onStatusChanged(String provider, int status, Bundle extras) {}
};
LocationListener locationListenerNetwork = new LocationListener() {
public void onLocationChanged(Location location) {
timer1.cancel();
locationResult.gotLocation(location);
lm.removeUpdates(this);
lm.removeUpdates(locationListenerGps);
}
public void onProviderDisabled(String provider) {
}
public void onProviderEnabled(String provider) {}
public void onStatusChanged(String provider, int status, Bundle extras) {}
};
class GetLastLocation extends TimerTask {
#Override
public void run() {
lm.removeUpdates(locationListenerGps);
lm.removeUpdates(locationListenerNetwork);
Location net_loc=null, gps_loc=null;
if(gps_enabled)
gps_loc=lm.getLastKnownLocation(LocationManager.GPS_PROVIDER);
if(network_enabled)
net_loc=lm.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
//if there are both values use the latest one
if(gps_loc!=null && net_loc!=null){
if(gps_loc.getTime()>net_loc.getTime())
locationResult.gotLocation(gps_loc);
else
locationResult.gotLocation(net_loc);
return;
}
if(gps_loc!=null){
locationResult.gotLocation(gps_loc);
return;
}
if(net_loc!=null){
locationResult.gotLocation(net_loc);
return;
}
locationResult.gotLocation(null);
}
}
public static abstract class LocationResult{
public abstract void gotLocation(Location location);
}
}
