Connection being refused while sending data from Android app to server

Question

I'm new to android application development and i want to send three parameters Latitude , Longitude and Bimari(which i am mentioning in my code below) to phpMyAdmin server via internet. The problem is that after selecting bimari from spinner when i click send button my app crashes. My server side is working correctly.Can anyone please tell me why i can't send my data to server ?

Thanks alot for reading !

MainActivity.java is as follows:-

public final static String EXTRA_MESSAGE = "com.example.sushma.myfirstapp.MESSAGE";


String nn, nn1, nn2, nn3, nn4, nn5, nnf;  // used to make URL
String sss1, sss2;  // used to convert lat and long to string
String s; // used to save bimari as string

double lat, lng;
LocationManager lm;

String provider;
Location l;
private View view;

@Override
protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    lm = (LocationManager)this.getSystemService(Context.LOCATION_SERVICE);
    Criteria c = new Criteria();
    provider = lm.getBestProvider(c, false);
    l = lm.getLastKnownLocation(provider);

    if (l != null) {

     //get latitude and longitude of the location
     lng = l.getLongitude();
     lat = l.getLatitude();

     } else {
    System.out.println("No lat/long");

    }

    {


        LinearLayout l1 = new LinearLayout(this);
        l1.setBackgroundResource(R.drawable.ambulance);
        setContentView(R.layout.activity_main);
    }
}


public void ongobuttonclick(View view) {
    this.view = view;

    Spinner sp = (Spinner) findViewById(R.id.problems);

    s = sp.getSelectedItem().toString();
    sss1 = String.valueOf(lng);
    sss2 = String.valueOf(lat);

    nn = "http://192.168.2.8/tech/new_predict.php?Latitude=";
    nn1 = sss2;
    nn2 = "&Longitude=";
    nn3 = sss1;
    nn4 = "&Bimari=";
    nn5 = s;

    nnf = nn + nn1 + nn2 + nn3 + nn4 + nn5;

    HttpClient httpclient = new DefaultHttpClient();
    HttpPost httPost = new HttpPost(nnf);
    System.out.println(nnf);
    new Thread(new Runnable() {
        @Override
        public void run() {
            try {
                httpclient.execute(httPost);
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }).start();
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.menu_main, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();

    //noinspection SimplifiableIfStatement
    if (id == R.id.action_settings) {
        return true;
    }

    return super.onOptionsItemSelected(item);
}

You tried execute httpclient.execute(httPost); method in UI thread. You can not do this.

You can use AsyncTask to resolve this issue.

public void ongobuttonclick(View view) {

     ...
    //your code 

    //use AsyncTask if you  want ot inform ui thread
     final HttpClient httpclient = new DefaultHttpClient();
    final HttpPost httPost = new HttpPost(nnf);

    new AsyncTask<HttpPost, Void, HttpResponse>() {
        //YourParams, YourProgress, YourResult can be Void
        @Override
        protected HttpResponse doInBackground(HttpPost... params) {
            HttpResponse response = null;
            try {
               response = httpclient.execute(params[0]);
            } catch (IOException e) {
                e.printStackTrace();
            }
            return response;
        }

        @Override
        protected void onPostExecute(HttpResponse response) {
            if(response != null){
                //do sth in UI thread
            }
        }
    }.execute(httPost);

    //or in new thread if you doesn't want ot inform ui thread
    new Thread(new Runnable() {
        @Override
        public void run() {
            try {
                httpclient.execute(httPost);
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }).start();
}

okay sir , but i would be very thankful if you could guide me where i have to execute httpclient.execute(httPost); . I am really a novice in android. – SUNIL KAPUR Jan 26 '15 at 16:26
wait I will edit my post – Konrad Krakowiak Jan 26 '15 at 16:27
Sir actually i have tried to use Async Task already but couldn't understand (protected string doInBackground(String... urls)) string as return type , as i have to post my variables on server , i don't need to return anything . So how can i proceed further . If anyways you could sum up that part of code and post it here i would be extremely thankful – SUNIL KAPUR Jan 26 '15 at 16:33
One more question isn't Async Task for downloading stuff from a web page ? – SUNIL KAPUR Jan 26 '15 at 16:34
I give you two solution first is how to use AsyncTask the second is how to use thread – Konrad Krakowiak Jan 26 '15 at 16:34
I show you how to execute your httPost if you want to do something with this you have to handle response – Konrad Krakowiak Jan 26 '15 at 16:36
Look on my post one more time. I edited AsyncTask. Do you see? How you execute your request in some thread and you can handle it in UI thread – Konrad Krakowiak Jan 26 '15 at 16:38
Okay sir so let me sum up just to clarify myself There are two solutions In the first one that is async task Do i need to pass any parameters or just the way you have posted it on ? Ques 2 If i use the second method of new thread do i need to pass anything as parameter – SUNIL KAPUR Jan 26 '15 at 16:43
I made one more edit. You have two solution First with AsyncTask the second with thread. If you want to do something with HttpResponse on UI thread you have to use AsyncTask and do it in postExecute method as is shown in code in post. If you want just execute http request and you doesn't care about HttpResponse you can use Thread – Konrad Krakowiak Jan 26 '15 at 16:50
Sir according to my requirement i implemented the second way and i am just left with the following two errors 01-26 22:23:53.714 21425-21425/com.example.sushma.myfirstapp E/ViewRootImpl﹕ sendUserActionEvent() mView == null 01-26 22:23:58.959 21425-22036/com.example.sushma.myfirstapp W/System.err﹕ org.apache.http.conn.HttpHostConnectException: Connection to http://192.168.2.8 refused – SUNIL KAPUR Jan 26 '15 at 17:00
Did you try open this url in phone by browser? You get Connection to 192.168.2.8 refused. You can be in different network than server – Konrad Krakowiak Jan 26 '15 at 17:04
Sir i have edited my code above in MainActivity.java please have a look(using a new thread) And regarding connection my browser is on my laptop where i am running phpmyadmin server and i am testing my app on my mobile . And my phone and laptop(server) are connected to the same wifi network . – SUNIL KAPUR Jan 26 '15 at 17:12
Could you attach your log? – Konrad Krakowiak Jan 26 '15 at 18:09
Sir i have attached my new logcat – SUNIL KAPUR Jan 27 '15 at 03:37
It's look that problem is on server site. Try open http://192.168.2.8/tech/new_predict.php?Latitude=31.310573780338718&Longitude=75.55498407042245&Bimari=Bones this link in some browser on your phone. – Konrad Krakowiak Jan 27 '15 at 08:52
