Hi, my app that I am making is not working. Here is the code:

package com.awsomechat;

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

        initialise();
    }

    private void initialise() {
        // TODO Auto-generated method stub

        blogin = (Button) findViewById(R.id.etSubmit);
        blogin.setOnClickListener(this);

    }

        try {

            nameValuePairs.add(new BasicNameValuePair("username", username));
            nameValuePairs.add(new BasicNameValuePair("password", password));

            httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

            response = httpclient.execute(httppost);

            if(response.getStatusLine().getStatusCode() == 200){

                // Get the info given to us.
                entity = response.getEntity();

                if(entity != null){
                    InputStream instream = entity.getContent();

                    JSONObject jsonResponse = new JSONObject(convertStreamToString(instream));

                    String retPass = jsonResponse.getString("password");

                    // Start the validation process
                    if(username.equals(retUser) && password.equals(retPass)){
                        //
                        //
                        SharedPreferences sp = getSharedPreferences("logindetails", 0);

                        SharedPreferences.Editor spedit = sp.edit();

                        spedit.putString("user", username);
                        spedit.putString("pass", password);

                    } else {
                        Toast.makeText(getBaseContext(), "Login Fialed.", Toast.LENGTH_SHORT).show();
                    }

        }
    }

    private static String convertStreamToString(InputStream is) {
        /*
         * To convert the InputStream to String we use the BufferedReader.readLine()
         * method. We iterate until the BufferedReader return null which means
         * there's no more data to read. Each line will appended to a StringBuilder
         * and returned as String.
         */
        BufferedReader reader = new BufferedReader(new InputStreamReader(is));

}

I am not sure what is making this app not work. I don't know how to fix this. The wierd thing is is that LogCat did not display anything, nor the Console. I really don't know what is wrong here.

You sure it is Android app and not your website that is problematic? I got this error when visited login

@peter_budo it still does not work after I fixed the login.php

I will try to have look at it later, just returned from holidays...
