Android error : org.apache.http.conn.ConnectTimeoutException

Question

I am working on JSON data parsing, I am new to this as i am doing JSON parsing for the first time. I tried an example from This Link. It runs fine. But when i change the example code according to my need i got error. My changed code is as follows :

MainActivity.Java

public class MainActivity extends ListActivity {

private ProgressDialog pDialog;

// URL to get contacts JSON
private static String url = "https://123.xxx.x.xxx/DEMO/login_data.php";

// JSON Node names
private static final String TAG_STATUS = "Status";
private static final String TAG_USERNAME = "User Name";
private static final String TAG_PASSWORD = "Admin password";

// contacts JSONArray
JSONArray sampleData = null;

// Hashmap for ListView
ArrayList<HashMap<String, String>> userNamePass;

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

    userNamePass = new ArrayList<HashMap<String, String>>();

    ListView lv = getListView();

    // Listview on item click listener
    lv.setOnItemClickListener(new OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> parent, View view,
                int position, long id) {
            // getting values from selected ListItem
            String name = ((TextView) view.findViewById(R.id.name))
                    .getText().toString();
            String cost = ((TextView) view.findViewById(R.id.password))
                    .getText().toString();

            // Starting single contact activity
            Intent in = new Intent(getApplicationContext(),SingleContactActivity.class);
            in.putExtra(TAG_USERNAME, name);
            in.putExtra(TAG_PASSWORD, cost);
            startActivity(in);

        }
    });

    // Calling async task to get json
    new GetContacts().execute();
}

        pDialog.setMessage("Please wait...");
        pDialog.setCancelable(false);
        pDialog.show();

    }

        String jsonStr = sh.makeServiceCall(url, ServiceHandler.POST);

        Log.d("Response: ", "> " + jsonStr);

        if (jsonStr != null) {
            try {
                JSONObject jsonObj = new JSONObject(jsonStr);

                // Getting JSON Array node
                sampleData = jsonObj.getJSONArray(TAG_STATUS);

                // looping through All Contacts
                for (int i = 0; i < sampleData.length(); i++) {
                    JSONObject c = sampleData.getJSONObject(i);

                    String name = c.getString(TAG_USERNAME);
                    String password = c.getString(TAG_PASSWORD);

Where i am wrong or what steps should i follow not to acheve my task. Please give your valuable suggestions...

Answer 1

Confirm that your URL is right or not. I faced the same issue as my URL is http:// and i am accessing it as https://.

May be your URL is like :

// URL to get contacts JSON
private static String url = "http://123.xxx.x.xxx/DEMO/login_data.php";

Answer 2

Your URL is most likely invalid. Change it to your appropriate URL.

private static String url = "https://123.xxx.x.xxx/DEMO/login_data.php";

That just doesn't look like any URL I've ever seen...

In the event that you masked it for SO, then make sure you get something by typing the same URL into a web browser, including the formatted strings. The best way to ensure this is to print the URL used immediately before using it, to ensure that nothing unusual has been added, and that the URL works exactly as intended.

As this is a local URL, it could be that your device isn't connected to the appropriate network. Try pinging the local URL from your phone (There's several utilities to try this, just look around).
