Run Gps as background service and send coordinates to web server (PHP)

Just create a service that runs in the background all the time.

For Example:-

AndroidLocationServices

public class AndroidLocationServices extends Service {WakeLock wakeLock;private LocationManager locationManager;public AndroidLocationServices() {    // TODO Auto-generated constructor stub}@Overridepublic IBinder onBind(Intent arg0) {    // TODO Auto-generated method stub    return null;}@Overridepublic void onCreate() {    // TODO Auto-generated method stub    super.onCreate();    PowerManager pm = (PowerManager) getSystemService(this.POWER_SERVICE);    wakeLock = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "DoNotSleep");    // Toast.makeText(getApplicationContext(), "Service Created",    // Toast.LENGTH_SHORT).show();    Log.e("Google", "Service Created");}@Override@Deprecatedpublic void onStart(Intent intent, int startId) {    // TODO Auto-generated method stub    super.onStart(intent, startId);    Log.e("Google", "Service Started");    locationManager = (LocationManager) getApplicationContext()            .getSystemService(Context.LOCATION_SERVICE);    locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,            5000, 5, listener);}private LocationListener listener = new LocationListener() {    @Override    public void onLocationChanged(Location location) {        // TODO Auto-generated method stub        Log.e("Google", "Location Changed");        if (location == null)            return;        if (isConnectingToInternet(getApplicationContext())) {            JSONArray jsonArray = new JSONArray();            JSONObject jsonObject = new JSONObject();            try {                Log.e("latitude", location.getLatitude() + "");                Log.e("longitude", location.getLongitude() + "");                jsonObject.put("latitude", location.getLatitude());                jsonObject.put("longitude", location.getLongitude());                jsonArray.put(jsonObject);                Log.e("request", jsonArray.toString());                new LocationWebService().execute(new String[] {                        Constants.TRACK_URL, jsonArray.toString() });            } catch (Exception e) {                // TODO Auto-generated catch block                e.printStackTrace();            }        }    }    @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    }};@Overridepublic void onDestroy() {    // TODO Auto-generated method stub    super.onDestroy();    wakeLock.release();}public static boolean isConnectingToInternet(Context _context) {    ConnectivityManager connectivity = (ConnectivityManager) _context            .getSystemService(Context.CONNECTIVITY_SERVICE);    if (connectivity != null) {        NetworkInfo[] info = connectivity.getAllNetworkInfo();        if (info != null)            for (int i = 0; i < info.length; i++)                if (info[i].getState() == NetworkInfo.State.CONNECTED) {                    return true;                }    }    return false;}}

LocationWebService

public class LocationWebService extends AsyncTask<String, String, Boolean> {public LocationWebService() {    // TODO Auto-generated constructor stub}@Overrideprotected Boolean doInBackground(String... arg0) {    ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();    nameValuePairs.add(new BasicNameValuePair("location", arg0[1]));    HttpClient httpclient = new DefaultHttpClient();    HttpPost httppost = new HttpPost(arg0[0]);    HttpParams httpParameters = new BasicHttpParams();    httpclient = new DefaultHttpClient(httpParameters);    try {        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));        HttpResponse response;        response = httpclient.execute(httppost);        StatusLine statusLine = response.getStatusLine();        if (statusLine.getStatusCode() == HttpStatus.SC_OK) {            Log.e("Google", "Server Responded OK");        } else {            response.getEntity().getContent().close();            throw new IOException(statusLine.getReasonPhrase());        }    } catch (Exception e) {        e.printStackTrace();    }    return null;}}
