Not moving to profile screen even after giving genuine credentials in login page

Question

In database we have login details {"email":"nagu@gmail.com","pwd":"12345"}.By using REST services I got the URL, I need to validate the credentials and move to next screen. But unable to move to next screen so please help me

public class LoginScreen extends DIBaseActivty {

public static final int CONNECTION_TIMEOUT=10000;
public static final int READ_TIMEOUT=15000;

private EditText editTextUsername;
private EditText editTextPassword;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_login_screen);

    editTextUsername = (EditText)findViewById(R.id.emaiId);
    editTextPassword = (EditText)findViewById(R.id.password);

}

public void buttonLogin (View arg0)
{
    final String username = editTextUsername.getText().toString();
    final String password = editTextPassword.getText().toString();
    new TaskLogin().execute(username,password);
}

public class TaskLogin extends AsyncTask<String,String,String>
{
    ProgressDialog pdLoading = new ProgressDialog(LoginScreen.this);
    HttpURLConnection conn;
    URL url = null;

    @Override
    protected void onPreExecute() {
        super.onPreExecute();

        pdLoading.setMessage("\t Loading...");
        pdLoading.setCancelable(false);
        pdLoading.show();
    }

    @Override
    protected String doInBackground(String... params) {
        try{
            url = new URL("http://localhost:8080/RestSpring/DialysisInfo/login");
        } catch (MalformedURLException e) {
            e.printStackTrace();
            return "exception";
        }
        try{
            conn = (HttpURLConnection)url.openConnection();
            conn.setReadTimeout(READ_TIMEOUT);
            conn.setConnectTimeout(CONNECTION_TIMEOUT);
            conn.setRequestMethod("POST");

            conn.setDoInput(true);
            conn.setDoOutput(true);

            Uri.Builder builder = new Uri.Builder()
                    .appendQueryParameter("username",params[0])
                    .appendQueryParameter("password",params[1]);
            String query = builder.build().getEncodedQuery();

            OutputStream os = conn.getOutputStream();
            BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(os,"UTF-8"));
            writer.write(query);
            writer.flush();
            writer.close();
            os.close();
            conn.connect();
        } catch (IOException e1)
        {
            e1.printStackTrace();
            return "Exception";
        }
        try{
            int response_code = conn.getResponseCode();
            if(response_code==HttpURLConnection.HTTP_OK)
            {
                InputStream input = conn.getInputStream();
                BufferedReader reader = new BufferedReader(new InputStreamReader(input));
                StringBuilder result = new StringBuilder();
                String line;
                while ((line= reader.readLine())!=null)
                {
                    result.append(line);
                }
                return (result.toString());
            } else { return ("unsuccessful");
            }

        } catch (IOException e)
        {
            e.printStackTrace();
            return "Exception";
        } finally {
            conn.disconnect();
        }
    }

    @Override
    protected void onPostExecute(String result) {
        pdLoading.dismiss();
        if(result.equalsIgnoreCase("true"))
        {
            Intent intent = new Intent(LoginScreen.this,DIUserProfile.class);
            startActivity(intent);
            LoginScreen.this.finish();
        }else if (result.equalsIgnoreCase("false"))
        {
            Toast.makeText(LoginScreen.this, "Invalid email or password", Toast.LENGTH_LONG).show();
        } else if(result.equalsIgnoreCase("exception") || result.equalsIgnoreCase("unsuccessful"))
        {
            Toast.makeText(LoginScreen.this, "OOPs! Something went wrong. Connection Problem.", Toast.LENGTH_LONG).show();
        }
    }
}
}

Here is my error log

It causes an excepion. Try to debug and find the point where it causes an exception — Pragnesh Ghoda シ, Feb 02 '17 at 05:29
is your URL publicly accessible? or at first check your URL in your phone/emulator browser . — , Feb 02 '17 at 05:38
@Prag'sシ i'm new to android and unable to find exact exception, URL cannot accessible — nikhil jack, Feb 02 '17 at 05:42
Try to give you pc's ip address instead of `localhost`, if you are on same intranet — Paresh P., Feb 02 '17 at 05:58
have you added permission of access_network_state in manifest ? — Pragnesh Ghoda シ, Feb 02 '17 at 07:20
@NikhilKulkarni Things to notice : 1st you have to change your url from localhost to IP address. 2nd you must have connected to the local server. otherwise your device can not be connected to the local server url. Try to run it from emmulator and if you are using wifi, you have to use LAN wifi for running this service in your device. — Pragnesh Ghoda シ, Feb 02 '17 at 09:22
same way i tried what you said but still i did not get the result..!! is it possible to come teamviewer to solve? — nikhil jack, Feb 02 '17 at 09:59

From your logcat:

java.net.ConnectException: failed to connect to localhost/127.0.0.1 (port 8080) after 10000ms: isConnected failed: ECONNREFUSED (Connection refused)

Your Android app failed to connect to the server. Set debug breakpoints and check the following:

Url is correct
Method name is correct
Parameters key and value are correct
Server is working fine or not

Unable to find out where the exception is – nikhil jack Feb 02 '17 at 10:12
From the URL (localhost/127.0.0.1). i think you have hosted it in your pc(Think how can a mobile communicate with Data which is local to your computer). try hosting it live then check. – saravanan r Feb 02 '17 at 10:16
I'm using IP address instead of local host..!! what else you want me to change? – nikhil jack Feb 02 '17 at 10:23

Since you have not specified you are connected to a server from the device or emulator so I guess you are using your application in the emulator.

If you are referring your localhost on your system from the Android emulator then you have to use http://10.0.2.2:8080/ Because Android emulator runs in a Virtual Machine therefore here 127.0.0.1 or localhost will be emulator's own loopback address.

Replace: url = http://localhost:8080/RestSpring/DialysisInfo/login"

With : url = "http://10.0.2.2:8080/RestSpring/DialysisInfo/login"

Try to open 10.0.2.2:8080/RestSpring/DialysisInfo/login url from your machine if it's not working then there may be issue with your firewall let me know that if it's working with your pc. – Pranav Darji Feb 02 '17 at 05:58

So might be the problem with your IIS Server if you are using Windows so first thing is upload your WebService to IIS server and try to open from IIS server if it will work then you just need to use the same url in android. – Pranav Darji Feb 02 '17 at 06:28
I'm not aware of this iis server... can you help me how to use that one – nikhil jack Feb 02 '17 at 06:49
In case if you are using .Net service then follow this link to deploy service on IIS http://programmerguru.com/webservice-tutorial/how-to-deploy-asp-dot-net-webservice-in-iis/ – Pranav Darji Feb 02 '17 at 06:52
i'm Using REST Api – nikhil jack Feb 02 '17 at 07:25
i'm using remote system from local system.. i should work in remote machine only – nikhil jack Feb 02 '17 at 08:43
Okay and what about device are you using emulator or Genymotion or real device for testing? – Pranav Darji Feb 02 '17 at 08:49
Android Studio's AVD only – nikhil jack Feb 02 '17 at 08:55
Follow this link http://stackoverflow.com/a/15864222/6032850 and let me know if your problem is solved or not. – Pranav Darji Feb 02 '17 at 09:13
