Implementing a background service to catch location

I have an app that can capture fotos and send to the server.
I need to get location(lat,lon,alt) everytime i take a foto.
After a lot of research i understood that taking this data requires some time, the gps triangulation must run asyncronous, so i tried to figure out the best way to do this.
After some time, i had the idea, to start a service, everytime i run the aplication, this service will grab the last location everytime, and when i send a foto i will get the last location values.
So i did something like this(Service):
package com.example.afcosta.inesctec.pt.android.services;
import android.app.Service;
import android.content.Intent;
import android.location.Location;
import android.location.LocationManager;
import android.os.Bundle;
import android.os.IBinder;
import android.util.Log;
public class MyService extends Service {
private static final String TAG = "BOOMBOOMTESTGPS";
private LocationManager mLocationManager = null;
private static final int LOCATION_INTERVAL = 1000;
private static final float LOCATION_DISTANCE = 10f;
private class LocationListener implements android.location.LocationListener
{
Location mLastLocation;
public LocationListener(String provider)
{
Log.e(TAG, "LocationListener " + provider);
mLastLocation = new Location(provider);
}
#Override
public void onLocationChanged(Location location)
{
Log.e("asd", "onLocationChanged: " + location);
mLastLocation.set(location);
}
#Override
public void onProviderDisabled(String provider)
{
Log.e(TAG, "onProviderDisabled: " + provider);
}
#Override
public void onProviderEnabled(String provider)
{
Log.e(TAG, "onProviderEnabled: " + provider);
}
#Override
public void onStatusChanged(String provider, int status, Bundle extras)
{
Log.e(TAG, "onStatusChanged: " + provider);
}
}
LocationListener[] mLocationListeners = new LocationListener[] {
new LocationListener(LocationManager.GPS_PROVIDER),
new LocationListener(LocationManager.NETWORK_PROVIDER)
};
#Override
public IBinder onBind(Intent arg0)
{
return null;
}
#Override
public int onStartCommand(Intent intent, int flags, int startId)
{
Log.e(TAG, "onStartCommand");
super.onStartCommand(intent, flags, startId);
return START_STICKY;
}
#Override
public void onCreate()
{
Log.e(TAG, "onCreate");
initializeLocationManager();
try {
mLocationManager.requestLocationUpdates(
LocationManager.NETWORK_PROVIDER, LOCATION_INTERVAL, LOCATION_DISTANCE,
mLocationListeners[1]);
} catch (java.lang.SecurityException ex) {
Log.i(TAG, "fail to request location update, ignore", ex);
} catch (IllegalArgumentException ex) {
Log.d(TAG, "network provider does not exist, " + ex.getMessage());
}
try {
mLocationManager.requestLocationUpdates(
LocationManager.GPS_PROVIDER, LOCATION_INTERVAL, LOCATION_DISTANCE,
mLocationListeners[0]);
} catch (java.lang.SecurityException ex) {
Log.i(TAG, "fail to request location update, ignore", ex);
} catch (IllegalArgumentException ex) {
Log.d(TAG, "gps provider does not exist " + ex.getMessage());
}
}
#Override
public void onDestroy()
{
Log.e(TAG, "onDestroy");
super.onDestroy();
if (mLocationManager != null) {
for (int i = 0; i < mLocationListeners.length; i++) {
try {
mLocationManager.removeUpdates(mLocationListeners[i]);
} catch (Exception ex) {
Log.i(TAG, "fail to remove location listners, ignore", ex);
}
}
}
}
private void initializeLocationManager() {
Log.e(TAG, "initializeLocationManager");
if (mLocationManager == null) {
mLocationManager = (LocationManager) getApplicationContext().getSystemService(this.LOCATION_SERVICE);
}
}
}
and then i call the service when my app runs(at the moment i am testing this just with login(onCreate))
startService(new Intent(this, MyService.class));
i get this logTrace(with red):
`05-22 20:35:39.652 32426-32426/com.example.afcosta.inesctec.pt.android E/BOOMBOOMTESTGPS: LocationListener gps

`
i don't get any location, i don't know why, the onlocationchanged never runs, if the location doesn't change i want to get the last.
How can i accomplish that?
Thanks

You don't need service class as you can get location in activity in which you are taking photos.
So first of all add permissions in manifest file
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
and dependencies in gradle
compile 'com.google.android.gms:play-services:10.2.6'
Then in activity in which you are taking photos
Implement listeners
public class Activity extends AppCompatActivity implements ConnectionCallbacks, OnConnectionFailedListener{
protected Location mLastLocation;
private double Latitude;
private double Longitude;
in onCreate method ask user for location permission and call
buildGoogleApiClient();
and then define buildGoogleApiClient() method
/**
* Builds a GoogleApiClient. Uses the addApi() method to request the LocationServices API.
*/
protected synchronized void buildGoogleApiClient() {
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.addApi(LocationServices.API)
.build();
}
after that implements listener interfaces methods
#Override
public void onConnected(Bundle connectionHint) {
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
return;
}
mLastLocation = LocationServices.FusedLocationApi.getLastLocation(mGoogleApiClient);
if (mLastLocation != null) {
Latitude = mLastLocation.getLatitude();
Longitude = mLastLocation.getLongitude();
}
}
#Override
public void onConnectionFailed(ConnectionResult result) {
// Refer to the javadoc for ConnectionResult to see what error codes might be returned in
// onConnectionFailed.
Log.i(TAG, "Connection failed: ConnectionResult.getErrorCode() = " + result.getErrorCode());
}
#Override
public void onConnectionSuspended(int cause) {
// The connection to Google Play services was lost for some reason. We call connect() to
// attempt to re-establish the connection.
Log.i(TAG, "Connection suspended");
mGoogleApiClient.connect();
}
then at the end
#Override
protected void onStop() {
super.onStop();
if (mGoogleApiClient.isConnected()) {
mGoogleApiClient.disconnect();
}
}
#Override
protected void onStart() {
super.onStart();
mGoogleApiClient.connect();
}
let me know if you don't understand anything

GoogleApiClient OnConnected Not Called unless Service is stopped

I am calling a service which connects to googleapiclient. Whenever the service is called first time, everything works smooth, client is connected, Onconnected is called. But the moment I recall service without stopping, I get googleapiclient connected but Onconnected is never called. Why So? Is there required to terminate service everytime. Here is the code:
public class ALW extends Service implements GoogleApiClient.OnConnectionFailedListener, GoogleApiClient.ConnectionCallbacks, LocationListener {
private GoogleApiClient mGoogleApiClient;
#Override
public void onDestroy() {
super.onDestroy();
if (mGoogleApiClient.isConnected()) {
mGoogleApiClient.disconnect();
}
Log.d("ALWFA", "Stopped");
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
Log.d("ALWFA", "Called");
if (!mGoogleApiClient.isConnected()) {
Log.e("ALWFA", "Called for Connection");
mGoogleApiClient.connect();
} else {
Log.e("ALWFA", "Already Connected");
}
//Do Work
return super.onStartCommand(intent, flags, startId);
}
#Nullable
#Override
public IBinder onBind(Intent intent) {
return null;
}
#Override
public void onCreate() {
super.onCreate();
buildGoogleApiClient();
}
#Override
public void onConnected(#Nullable Bundle bundle) {
Log.d("Google Client", "Connected");
//Do work
}
#Override
public void onConnectionSuspended(int i) {
System.out.println("Connection Sus");
buildGoogleApiClient();
}
#Override
public void onConnectionFailed(#NonNull ConnectionResult connectionResult) {
Log.i("Connection Error", "onConnectionFailed:" + connectionResult.getErrorCode() + "," + connectionResult.getErrorMessage());
buildGoogleApiClient();
System.out.println("Connection Failed");
}
synchronized void buildGoogleApiClient() {
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.addApi(LocationServices.API)
.build();
}
}
and I m not getting any error in Onconenctiofailed. Normally code stuck at onStartCommand: "ALWFA Called". whenever service is called second time.

You should check before calling it again like this
if(mGoogleApiClient!=null && !mGoogleApiClient.isConnected())
{
//Do your work
}
and implement these methods
#Override
protected void onStart() {
super.onStart();
if (mGoogleApiClient != null)
mGoogleApiClient.connect();
}
#Override
protected void onStop() {
super.onStop();
if (mGoogleApiClient != null)
mGoogleApiClient.disconnect();
}

Before any operation is executed, the GoogleApiClient must be connect using the 'connect()' method. The client is not considered connected until the onConnected(Bundle) callback has been called.
You should instantiate a client object in your Activity's 'onCreated(Bundle)' method then call connect() on onStart()
You may call startLocationUpdate() from the onConnected() callback
#Override
public void onConnected(Bundle connectionHint) {
...
if (mRequestingLocationUpdates) {
startLocationUpdates();
}
}
protected void startLocationUpdates() {
LocationServices.FusedLocationApi.requestLocationUpdates(
mGoogleApiClient, mLocationRequest, this);
}
Here's a Google Documentation regarding Location Updates: http://developer.android.com/training/location/receive-location-updates.html

android location apis : FusedLocationApi.getLastLocation is giving null

I am trying to find last known location of device using GoogleApiClient, So I used fine level access, but getting following exception because location coming is null.
E/AndroidRuntime: FATAL EXCEPTION: main
Process: com.example.kuldeep.location2, PID: 1421
java.lang.NullPointerException: Attempt to invoke virtual method 'double android.location.Location.getLatitude()' on a null object reference

private GoogleApiClient mGoogleApiClient;
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.addApi(LocationServices.API)
.build();
}
#Override

}
#Override
public void onConnected(Bundle bundle) {
try {
Location mLastLocation = LocationServices.FusedLocationApi.getLastLocation(
mGoogleApiClient);
Toast.makeText(this, mLastLocation.getLatitude() + ", " + mLastLocation.getLongitude(), Toast.LENGTH_SHORT);
} catch (SecurityException e){
e.printStackTrace();
}
}
My manifest file is as follow :
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.kuldeep.location2">
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
</manifest>

First of all, getLastLocation() can be null so you be carefull acessing directly to mLastLocation without a "null" check. In second place, i suggest you to add in your manifest:
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
and then call a LocationRequest.
if(locRequest== null)
{
locRequest= new LocationRequest();
locRequest.setInterval( interval );
locRequest.setFastestInterval( fastestInterval );
locRequest.setPriority( priority );
LocationServices.FusedLocationApi.requestLocationUpdates(yourGoogleApiClient, locRequest, this);
}

Using GoogleApiClient find a CurrentLocation like these:
private GoogleApiClient googleApiClient;
private Location mLastLocation;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
isCheckLocationServiceisOn(context);
if(googleApiClient == null) {
googleApiClient = new GoogleApiClient.Builder(this)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.addApi(LocationServices.API)
.build();
}
#Override
protected void onStart() {
mGoogleApiClient.connect();
super.onStart();
}
#Override
protected void onStop() {
mGoogleApiClient.disconnect();
super.onStop();
}
#Override
protected void onResume() {
super.onResume();
isCheckLocationServiceisOn(context);
}
#Override
public void onConnected(Bundle arg0) {
if(googleApiClient.isConnected()) {
mLastLocation = LocationServices.FusedLocationApi.getLastLocation(googleApiClient);
if (mLastLocation != null) {
System.out.println("latiTude....."+ String.valueOf(mLastLocation.getLatitude()));
System.out.println("longiTude....."+ String.valueOf(mLastLocation.getLongitude()));
}
}
}
#Override
public void onConnectionFailed(ConnectionResult arg0) {
System.out.println("onConnectionFailed...."+ arg0.toString());
}
#Override
public void onConnectionSuspended(int arg0) {
System.out.println("onConnectionSuspended...."+ arg0);
}
Add Permission in manifest:
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
Here,
Implements ConnectionCallbacks, OnConnectionFailedListener interface for that supported override methods they must be com.google.android.gms.common.api.GoogleApiClient package.
MUST REMEMBER:
Wi-Fi and GSM and GPS is must be on in device if not then generate these kind of error in onConnected()
I give you code to check & open location service also:
public static void isCheckLocationServiceisOn (final Context context) {
LocationManager lm = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);
boolean gps_enabled = false;
boolean network_enabled = false;
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) {
// notify user
AlertDialog.Builder dialog = new AlertDialog.Builder(context);
dialog.setMessage("Location Services Disabled. \n Please enable location services.");
dialog.setPositiveButton("Enable", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface paramDialogInterface, int paramInt) {
Intent myIntent = new Intent(android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS);
context.startActivity(myIntent);
//get gps
}
});
dialog.setNegativeButton("Cancle", new DialogInterface.OnClickListener() {
#Override

});
dialog.show();
}
}

Doesn't onConnected() imply GoogleApiClient is connected and ready to be used? How can I resolve this?

https://developer.android.com/reference/com/google/android/gms/common/api/GoogleApiClient.html
You should instantiate a client object in your Activity's onCreate(Bundle) method and then call connect() in onStart() and disconnect() in onStop(), regardless of the state.
The implementation of the GoogleApiClient appears designed for only a single instance. It's best to instantiate it only once in onCreate, then perform connections and disconnections using the single instance.

Maybe you should notice, GoogleApiClient.Builder has a method setAccountName(). You should invoke this method with your Google account name. I have tried, and succeeded. I used the following code:
if (mGoogleApiClient == null) {
mGoogleApiClient = new GoogleApiClient.Builder(context)
.addApi(LocationServices.API)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.setAccountName("李江涛")
.build();
}
if (mLocationRequest == null) {
mLocationRequest = new LocationRequest();
mLocationRequest.setInterval(10000);
mLocationRequest.setFastestInterval(5000);
mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
}

Try using com.google.android.gms.location.LocationClient instead of GoogleApiClient. Note that the ConnectionCallbacks and OnConnectionFailedListener interfaces that you implement will be slightly different.
Here's a quick example:
class LocationHandler implements ConnectionCallbacks,
OnConnectionFailedListener, LocationListener {
private LocationClient client;
void getLocation(Context context) {
client = new LocationClient(context, this, this);
client.connect();
}
#Override
public void onConnected(Bundle connectionHint) {
LocationRequest request = LocationRequest.create();
request.setNumUpdates(1);
client.requestLocationUpdates(request, this);
client.unregisterConnectionCallbacks(this);
}
#Override
public void onDisconnected() { }
#Override
public void onConnectionFailed(ConnectionResult result) {
// handle connection failure
}
#Override
public void onLocationChanged(Location location) {
client.removeLocationUpdates(this);
client.disconnect();
// do stuff with the location
}
}
