I'm trying to get location on android device But it crashes immediately after execution

Question

I'm trying to get location on android device the code is as follows:

private void openLocation() {
    lm = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
    Criteria c = new Criteria();
    pro = lm.getBestProvider(c,false);
    Location l = lm.getLastKnownLocation(pro);

    if (l != null) {
        Toast.makeText(WebActivity.this, "Longitude : "+String.valueOf(l.getLongitude())+", Latitude : "+String.valueOf(l.getLatitude()), Toast.LENGTH_LONG).show();
    } else {
        Toast.makeText(WebActivity.this,"loc object is null",Toast.LENGTH_LONG).show();
    }

    mgac = new GoogleApiClient.Builder(this)
            .addConnectionCallbacks(this)
            .addOnConnectionFailedListener(this)
            .addApi(LocationServices.API)
            .build();
}

but it crashes when executed. What's wrong in the code, or please give me a working code that give me location to string and I want to send the data to another url using get/post request and this request should run in background.

if it crashes first see is it consoling some error/exception in console, if yes what is it? — Akhilesh Kumar, May 31 '15 at 18:39

This might help u,

Thread thread = new Thread(new Runnable() {
            @Override
            public void run() {

            try {

                URL url = new URL(url);
                HttpURLConnection conn = (HttpURLConnection) url
                        .openConnection();
                conn.setReadTimeout(10000 /* milliseconds */);
                conn.setConnectTimeout(15000 /* milliseconds */);
                conn.setRequestMethod("GET");
                conn.setDoInput(true);
                // Starts the query

                conn.connect();
                InputStream stream = conn.getInputStream();

                String data = convertStreamToString(stream);

                // u can read data here
                stream.close();


            } catch (Exception e) {
            }
        }
    });

    thread.start();

& the convertStreamToString is,

static String convertStreamToString(java.io.InputStream is) {
        java.util.Scanner s = new java.util.Scanner(is).useDelimiter("\\A");
        return s.hasNext() ? s.next() : "";
    }

this can help you in sending the some request to server in background but for getting location I'm not very sure.

he wants to send These data to some url using get/post request and this request should run in background and I think this is a solution for that @Commons sir. — Akhilesh Kumar, May 31 '15 at 18:41
@AkhileshKumar you are right but it would be batter if you can answer my first question also — jai chandal, May 31 '15 at 18:46
