Android send Gps Data to server without a button press

Currently i have a class that sends data to the server on button press, i am looking to automate this service so that every 4 hrs it send the data to the server without pressing a button. The POST service is currently working in the background , Any pointers?? Do i have to implement a Timer no clue its out of my realm ?? Thanks in Advance !!

  Button btnCreateUser = (Button) findViewById(R.id.btnSend);
    // button click event
    btnCreateUser.setOnClickListener(new View.OnClickListener() {
        public void onClick(View view) {
            // creating new product in background thread
                new CreateNewUser().execute();
            }
    });
}

class CreateNewUser extends AsyncTask<String, String, String> {
    @Override
    protected String doInBackground(String... args)  {
        String lat=latitude, lng=longitude;
        SimpleDateFormat sdfDateTime = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss", Locale.US);
        String newtime =  sdfDateTime.format(new Date(System.currentTimeMillis()));
        EditText username = (EditText) findViewById(R.id.myText); 
        String newString= (String)username.getText().toString();
        String created_at=newtime;
        String timezone="UTC";
        HttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new HttpPost(url_create_user);
        String responseBody = "";
        HttpResponse response = null;

        try {

            String base64EncodedCredentials = "Basic " + Base64.encodeToString( 
          (username + ":" + created_at +":"+timezone+":"+lat+":"+lng).getBytes(), 
                    Base64.NO_WRAP);

            httppost.setHeader("Authorization", base64EncodedCredentials);
            httppost.setHeader(HTTP.CONTENT_TYPE,"application/json");
            JSONObject obj = new JSONObject();
            obj.put("username", String.valueOf(newString)); 
            obj.put("created_at",String.valueOf(newtime));
            obj.put("timezone", String.valueOf(timezone));
            obj.put("lat", String.valueOf(latitude));
            obj.put("lng", String.valueOf(longitude));
            httppost.setEntity(new StringEntity(obj.toString(), "UTF-8"));

            // Execute HTTP Post Request
            response = httpclient.execute(httppost);

            if (response.getStatusLine().getStatusCode() == 200) {

                Log.d("response ok", "Reached Server ok");
                 startActivity(new Intent("com.xxxxx.CLEARSCREEN"));

            } else {
                Log.d("response not ok", "Something went wrong :/");
            }
            responseBody = EntityUtils.toString(response.getEntity());

        } catch (ClientProtocolException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
        catch (JSONException e) {
           e.printStackTrace();
        }
        return responseBody;
    }

Use AlarmManager (http://developer.android.com/reference/android/app/AlarmManager.html) to start your activity repeatedly in future.

Assuming that the activity you use to collect user data and send them to server is called YourActivity just add some static methods as below for scheduling activity start. You may call the schedule method either on application start or from BOOT_COMPLETE BroadcastReceiver.

public static void schedule(Context context, String url,
        long triggerAtMillis, long intervalMillis) {
    final AlarmManager alarmManager =
            (AlarmManager) context.getSystemService(ALARM_SERVICE);
    alarmManager.setRepeating(AlarmManager.RTC, triggerAtMillis,
            intervalMillis, createPendingOperation(context));
}

public static void unschedule(Context context) {
    final AlarmManager alarmManager =
            (AlarmManager) context.getSystemService(ALARM_SERVICE);
    alarmManager.cancel(createPendingOperation(context));
}

private static PendingIntent createPendingOperation(Context context) {
    return PendingIntent.getActivity(
            context, 0, new Intent(context, YourActivity.class),
            PendingIntent.FLAG_CANCEL_CURRENT);
}

you can solve it by this code :

 Timer timer = new Timer();

  timer.scheduleAtFixedRate(new TimerTask() {
  public void run() {

    btnCreateUser.post(new Runnable() {
                @Override
                public void run() {
                    btnCreateUser .performClick();
                }
            }); 
  }
   }, 0, 14400); // for 4 hours
