How can I send HTTP Basic Authentication headers in Android?

Question

I am not sure how to send HTTP Auth headers.

I have the following HttpClient to get requests, but not sure how I can send requests?

public class RestClient extends AsyncTask<String, Void, JSONObject> {
        private 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));
            StringBuilder sb = new StringBuilder();

            String line = null;
            try {
                while ((line = reader.readLine()) != null) {
                    sb.append(line + "\n");
                }
            } catch (IOException e) {
                e.printStackTrace();
            } finally {
                try {
                    is.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }

            return sb.toString();
        }

        /*
         * This is a test function which will connects to a given rest service
         * and prints it's response to Android Log with labels "Praeda".
         */
        public JSONObject connect(String url) {
            HttpClient httpclient = new DefaultHttpClient();

            // Prepare a request object
            HttpGet httpget = new HttpGet(url);

            // Execute the request
            HttpResponse response;
            try {
                response = httpclient.execute(httpget);
                // Examine the response status
                Log.i("Praeda", response.getStatusLine().toString());

                // Get hold of the response entity
                HttpEntity entity = response.getEntity();

                if (entity != null) {

                    // A Simple JSON Response Read
                    InputStream instream = entity.getContent();
                    String result = convertStreamToString(instream);

                    // A Simple JSONObject Creation
                    JSONObject json = new JSONObject(result);

                    // Closing the input stream will trigger connection release
                    instream.close();

                    return json;
                }

            } catch (ClientProtocolException e) {
                e.printStackTrace();
            } catch (IOException e) {
                e.printStackTrace();
            } catch (JSONException e) {
                e.printStackTrace();
            }

            return null;
        }

        @Override
        protected JSONObject doInBackground(String... urls) {
            return connect(urls[0]);
        }

        @Override
        protected void onPostExecute(JSONObject json) {

        }
    }

This is covered in the HttpClient documentation and in their sample code.

Some methods in the documentation don't exist on the android platform.

Maybe the documentation of HttpClient can help: link

FYI, your link is for HttpClient 3.x, and Android has HttpClient 4.x built in.

Since Android compiles HttpClient 4.0.x instead of 3.x, below snippet is for your reference.

    if (authState.getAuthScheme() == null) {
        AuthScope authScope = new Au    HttpRequestInterceptor preemptiveAuth = new HttpRequestInterceptor() {
    public void process(final HttpRequest request, final HttpContext context) throws HttpException, IOException {
        AuthState authState = (AuthState) context.getAttribute(ClientContext.TARGET_AUTH_STATE);
        CredentialsProvider credsProvider = (CredentialsProvider) context.getAttribute(
                ClientContext.CREDS_PROVIDER);
        HttpHost targetHost = (HttpHost) context.getAttribute(ExecutionContext.HTTP_TARGET_HOST);thScope(targetHost.getHostName(), targetHost.getPort());
        Credentials creds = credsProvider.getCredentials(authScope);
        if (creds != null) {
            authState.setAuthScheme(new BasicScheme());
            authState.setCredentials(creds);
        }
    }
}    
};
DefaultHttpClient httpclient = new DefaultHttpClient();
httpclient.addRequestInterceptor(preemptiveAuth, 0);
