Http Get using Android HttpURLConnection

Try getting the input stream from this you can then get the text data as so:-

    URL url;    HttpURLConnection urlConnection = null;    try {        url = new URL("http://www.mysite.se/index.asp?data=99");        urlConnection = (HttpURLConnection) url                .openConnection();        InputStream in = urlConnection.getInputStream();        InputStreamReader isw = new InputStreamReader(in);        int data = isw.read();        while (data != -1) {            char current = (char) data;            data = isw.read();            System.out.print(current);        }    } catch (Exception e) {        e.printStackTrace();    } finally {        if (urlConnection != null) {            urlConnection.disconnect();        }        }

You can probably use other inputstream readers such as buffered reader also.

The problem is that when you open the connection - it does not 'pull' any data.

Here is a complete AsyncTask class

public class GetMethodDemo extends AsyncTask<String , Void ,String> {    String server_response;    @Override    protected String doInBackground(String... strings) {        URL url;        HttpURLConnection urlConnection = null;        try {            url = new URL(strings[0]);            urlConnection = (HttpURLConnection) url.openConnection();            int responseCode = urlConnection.getResponseCode();            if(responseCode == HttpURLConnection.HTTP_OK){                server_response = readStream(urlConnection.getInputStream());                Log.v("CatalogClient", server_response);            }        } catch (MalformedURLException e) {            e.printStackTrace();        } catch (IOException e) {            e.printStackTrace();        }        return null;    }    @Override    protected void onPostExecute(String s) {        super.onPostExecute(s);        Log.e("Response", "" + server_response);    }}// Converting InputStream to Stringprivate String readStream(InputStream in) {        BufferedReader reader = null;        StringBuffer response = new StringBuffer();        try {            reader = new BufferedReader(new InputStreamReader(in));            String line = "";            while ((line = reader.readLine()) != null) {                response.append(line);            }        } catch (IOException e) {            e.printStackTrace();        } finally {            if (reader != null) {                try {                    reader.close();                } catch (IOException e) {                    e.printStackTrace();                }            }        }        return response.toString();    }

To Call this AsyncTask class

new GetMethodDemo().execute("your web-service url");

I have created with callBack(delegate) response to Activity class.

public class WebService extends AsyncTask<String, Void, String> {    private Context mContext;    private OnTaskDoneListener onTaskDoneListener;    private String urlStr = "";    public WebService(Context context, String url, OnTaskDoneListener onTaskDoneListener) {        this.mContext = context;        this.urlStr = url;        this.onTaskDoneListener = onTaskDoneListener;    }    @Override    protected String doInBackground(String... params) {        try {            URL mUrl = new URL(urlStr);            HttpURLConnection httpConnection = (HttpURLConnection) mUrl.openConnection();            httpConnection.setRequestMethod("GET");            httpConnection.setRequestProperty("Content-length", "0");            httpConnection.setUseCaches(false);            httpConnection.setAllowUserInteraction(false);            httpConnection.setConnectTimeout(100000);            httpConnection.setReadTimeout(100000);            httpConnection.connect();            int responseCode = httpConnection.getResponseCode();            if (responseCode == HttpURLConnection.HTTP_OK) {                BufferedReader br = new BufferedReader(new InputStreamReader(httpConnection.getInputStream()));                StringBuilder sb = new StringBuilder();                String line;                while ((line = br.readLine()) != null) {                    sb.append(line + "\n");                }                br.close();                return sb.toString();            }        } catch (IOException e) {            e.printStackTrace();        } catch (Exception ex) {            ex.printStackTrace();        }        return null;    }    @Override    protected void onPostExecute(String s) {        super.onPostExecute(s);        if (onTaskDoneListener != null && s != null) {            onTaskDoneListener.onTaskDone(s);        } else            onTaskDoneListener.onError();    }}

where

public interface OnTaskDoneListener {    void onTaskDone(String responseData);    void onError();}

You can modify according to your needs. It's for get
