Android服务没有停止

我创建了一项服务,将设备的位置发送到服务器,然后将该位置存储在数据库中。

在该服务中,我实现了一个LocationListner,并在onLocationChanged方法中,通过HttpPost将服务器发送到服务器的位置设置服务的警报(因为我希望它每小时发送一次),然后停止服务

问题是即使我称之为'自己',服务在停止前继续运行几次(如发送位置几次)。如何更改它以便他立即停止服务。

PFB onLocationChanged方法的代码

public void onLocationChanged(android.location.Location location) {
            if(location!=null)
            {
                System.out.println("here");
                latid = location.getLatitude();
                longid = location.getLongitude();
                 String userinfo = ``Double.toString(latid)+"&&&&"+Double.toString(longid);
                 Location = userinfo;

                 Toast.makeText(getApplicationContext(), Location, 1000).show();

                 HttpClient httpclient = new DefaultHttpClient();
                    HttpPost httppost = new HttpPost("http://www.easymontra.in/location/try.php");

                    List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
                    nameValuePairs.add(new BasicNameValuePair("lat", Double.toString(latid)));
                    nameValuePairs.add(new BasicNameValuePair("long", Double.toString(longid)));
                    try {
                        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
                    } catch (UnsupportedEncodingException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }

                    // Execute HTTP Post Request
                    try {
                        HttpResponse response = httpclient.execute(httppost);
                    } catch (ClientProtocolException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    } catch (IOException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }


                AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);



                    Calendar calendar = Calendar.getInstance();

                    calendar.setTimeInMillis(System.currentTimeMillis());

                    calendar.add(Calendar.MINUTE, 60);

                    alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), alarmIntent);

                    Toast.makeText(getApplicationContext(), "stopping now", 1000).show();
                   stopSelf();



            }

stopSelf()是一个请求,它取决于运行时,它处理请求的时间。它是一个异步方法调用,因此当调用此方法时,可能不会期望服务立即结束。此外,在您的情况下,您的服务停止时会触发更多位置更新,因此您可以使用locationManager.removeUpdates(locationListener);将其置于stopSelf();

之前停止侦听位置更新
