I start service from an android activity
startservice(intent);
stopservice(intent);
When i call for stopping service but service it does not stop actually my service class contains LocationListener that get latitude and longitude and then store in sqlite and also sent such information into server.
Another issue is LocationUpdate method is automatically call after second
How to extend time e.g 30 second
How to stop service to stop LocationListener and storing value in sqlite server.

Dear Attaullah use Periodic service. I had the same problem i solved like this. In my case this was the code.
Service Code:
public class PeriodicService extends Service {
Context context;
private MyTask task;
@Override
public void onCreate() {
// TODO Auto-generated method stub
super.onCreate();
this.context = (MainActivity) MainActivity.context;
RequestPackage p = new RequestPackage();
p.setMethod("GET");
p.setUri("http://192.168.137.1/new/connect.php");
p.setParams("param1", "" + MainActivity.lastIndex);
task = new MyTask(this);
task.execute(p);
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
task = new MyTask(this);
RequestPackage p = new RequestPackage();
p.setMethod("GET");
p.setUri("http://192.168.137.1/new/connect.php");
p.setParams("param1", "" + MainActivity.lastIndex);
task.execute(p);
return START_NOT_STICKY;
}
@Override
public IBinder onBind(Intent intent) {
// TODO Auto-generated method stub
return null;
}
@Override
public void onDestroy() {
// TODO Auto-generated method stub
super.onDestroy();
Intent ishintent = new Intent(this, PeriodicService.class);
PendingIntent pintent = PendingIntent.getService(this, 0, ishintent, 0);
AlarmManager alarm = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
alarm.cancel(pintent);
alarm.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(),
30000, pintent);
}
}
Start and stop your service
Call stop service method after start service. As according to the life cycle of the service the destroy method is called when the service is stopped. After stopping the service pending intent is used where the service is delayed for some time according to your choice.
Intent intent = new Intent(
"com.urdo.news.updates.latest.service.PeriodicService");
MainActivity.this.startService(intent);
stopService(intent);
MyTask Class
public class MyTask extends AsyncTask<RequestPackage, String, List<Flower>> {
Context context;
private ArrayList<MyTask> tasks;
List<Flower> flowerList;
LazyImageLoadAdapter adapter;
ProgressBar bar;
NewLocalDb db;
public MyTask(Context context) {
this.context = context;
tasks = new ArrayList<>();
db = new NewLocalDb(context);
}
@Override
protected void onPreExecute() {
tasks.add(this);
}
@Override
protected List<Flower> doInBackground(RequestPackage... params) {
String content = HttpManager.getData(params[0]);
if (content.trim().length() == 4) {
return null;
} else {
flowerList = FlowerJSONParser.parseFeed(content);
if (flowerList.size() > 0) {
for (int i = 0; i < flowerList.size(); i++) {
Flower flower = new Flower();
flower = flowerList.get(i);
int id = flower.getProductId();
String title = flower.getHealine();
String des = flower.getDetail();
String imageName = flower.getPhoto();
try {
if (db.isValueAvailable(id) > 0) {
Log.d("Valuexist", "value eixst");
} else {
db.addNews(id, title, des, imageName);
Log.d("TAG", imageName);
}
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
Log.d("ERRor", e.getMessage().toString());
}
}
} else {
return null;
}
flowerList = db.getAllNews();
db.close();
}
Log.d("EEEEEE", "" + content.trim().length());
return flowerList;
}
@SuppressWarnings("unused")
@Override
protected void onPostExecute(List<Flower> result) {
tasks.remove(this);
if (result == null) {
Toast.makeText(context, "Web service not available",
Toast.LENGTH_LONG).show();
return;
}
flowerList = result;
if (result != null) {
// add in data base
updateDisplay();
}
}
protected void updateDisplay() {
adapter = new LazyImageLoadAdapter(context, flowerList);
MainActivity.list.setAdapter(adapter);
MainActivity.lastIndex = MainActivity.list.getAdapter().getCount();
Toast.makeText(context, "" + MainActivity.lastIndex, 500).show();
}
}
M D
but service it does not stop.
Because you have return
return START_STICKY;
in onStartCommand(...)
read more at START_STICKY and START_NOT_STICKY
and Official docs
