Doubt in Android HTTP Get method?

[sowmya235]

We are facing problem in the below code while running the HTTP example[ we are not getting any response while running the below code]:Could anyone suggest us where we are going wrong?

Mainactivity.java:
public class MainActivity extends Activity {

TextView httpStuff;
private static String TAG = "Httpclient";

protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Log.d(TAG, "Inside main");
httpStuff = (TextView) findViewById(R.id.tvHttp);
//httpStuff.setText("Data returneedddd");

HttpClient newClient = new HttpClient(this);
newClient.sendHttpGetRequest("http://74.125.224.119");
}

HttpClient.java:
public class HttpClient extends DefaultHttpClient {

// Member variable
private Activity mMainActivity;
private HttpContext mHttpContext;
private static String TAG = "Httpclient";

/**
* Constructor
*/
HttpClient(Activity mainActivity) {

// Initialize member variables
mMainActivity = mainActivity;
mHttpContext = new BasicHttpContext();
}

/**
* Creates and send the Http get requests
*/
public void sendHttpGetRequest(String hostUrl) {

// Set the headers
HttpGet httpGet = new HttpGet(hostUrl);
httpGet.setHeader("Accept", "*/*");
httpGet.setHeader("Accept-Encoding", "identity");
httpGet.setHeader("X-Transcend-Version", "1");

// Send the request Async
HttpRequestAsync sendReqAsync = new HttpRequestAsync(mMainActivity, this, mHttpContext);
sendReqAsync.execute(httpGet);
}

public void sendHttpGetRequest(HttpGet httpGet) {

// Send the request Async to retrieve configuration file.
HttpRequestAsync sendReqAsync = new HttpRequestAsync(mMainActivity, this, mHttpContext);
sendReqAsync.execute(httpGet);
}
public void receivedResponse(HttpResponse response) {

//TextView httpStuff = (TextView)mMainActivity.findViewById(R.id.tvHttp);

if(response != null) {

if (response.getStatusLine().getStatusCode() != HttpStatus.SC_OK) {
Log.d(TAG, response.getStatusLine().toString());
//httpStuff.setText(response.getStatusLine().toString());
} else {


try {

InputStream inputStream = response.getEntity().getContent();
Reader inputStreamReader = new InputStreamReader(inputStream, "UTF-8");

// Read the data from the InputStream
char[] buffer = new char[100];
StringBuilder readData = new StringBuilder();
int read;
Log.d(TAG, "Got HTTP Response");
Log.d(TAG, inputStreamReader.toString());
do {
read = inputStreamReader.read(buffer, 0, buffer.length);
Log.d(TAG, "Read val" + read);
if (read>0) {
Log.d(TAG, "Readdinggg dataaa");
readData.append(buffer, 0, read);
}
} while (read>=0);
Log.d(TAG, "out of the while loop");
Log.d(TAG, "Received data" + readData.toString());
//httpStuff.setText(readData);

} catch (IOException e) {
Log.d(TAG, "IO exception");
} catch (IllegalStateException e) {
Log.d(TAG, "IllegalStateException");
} catch (IndexOutOfBoundsException e ) {
Log.d(TAG, "Index out of bound exception");
}
}
}
}
}

HttpRequestAsync.java:
public class HttpRequestAsync extends AsyncTask<HttpUriRequest, Integer, HttpResponse> {

private static String TAG = "Httpclient";
private HttpClient mHttpClient;
private HttpContext mHttpContext;

/**
* Constructor
*/
HttpRequestAsync(Activity activity, HttpClient httpClient, HttpContext httpContext) {

// Initialize the member variables
mHttpClient = httpClient;
mHttpContext = httpContext;

// Create and initialize progress bar
}

/**
* Sends the input Http request in background thread
*/
@Override
protected HttpResponse doInBackground(HttpUriRequest... request) {

try {

// Send the Http Request
return mHttpClient.execute(request[0], mHttpContext);

} catch (ClientProtocolException e) {

// Send the error log to UI thread to update in the dialog
Log.d(TAG, e.getMessage());


} catch (IOException e) {

// Send the error log to UI thread to update in the dialog
Log.d(TAG, e.getMessage());
}

return null;
}

/**
* Runs on the UI thread.
* Starts a progress dialog and displays it.
*/
protected void onProgressUpdate (Integer... values) {
super.onProgressUpdate(values[0]);
//mDownloadProgressBar.show();
}

/**
* Gets the return value returned by doInBackground() and calls received response of HttpClient
*/
protected void onPostExecute (HttpResponse response) {
super.onPostExecute(response);

//mDownloadProgressBar.hide();
mHttpClient.receivedResponse(response);
}

}
