Hi Ludwig,
Thanks for ur Response.. i added that entry. After adding <uses-
permission> tag in androidmanifest.xml, i was getting
UnknownHostException...it was basically due to URL class....I replaced
everything with HTTPClient classes....
Here is my modified class and it worked me.....
import java.io.InputStream;
import javax.xml.parsers.SAXParser;
import javax.xml.parsers.SAXParserFactory;
import org.apache.commons.httpclient.HostConfiguration;
import org.apache.commons.httpclient.HttpConnection;
import org.apache.commons.httpclient.HttpConnectionManager;
import org.apache.commons.httpclient.HttpState;
import org.apache.commons.httpclient.HttpURL;
import org.apache.commons.httpclient.SimpleHttpConnectionManager;
import org.apache.commons.httpclient.methods.PostMethod;
import org.xml.sax.InputSource;
import org.xml.sax.XMLReader;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.widget.TextView;
public class ParsingXML extends Activity {
private final String DEBUG_TAG = "ParsingXML";
protected HttpConnectionManager connectionManager = new
SimpleHttpConnectionManager();
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
TextView tv = new TextView(this);
String baseURL = "http://www.anddev.org/images/tut/basic/
parsingxml/example.xml";
HttpConnection connection = null;
try{
HttpURL httpURL = new HttpURL(baseURL);
HostConfiguration host = new HostConfiguration();
host.setHost(httpURL.getHost(), httpURL.getPort());
connection = connectionManager.getConnection(host);
Log.d("MyLogger", "Before Opening Conn");
connection.open();
PostMethod postMethod = new PostMethod(baseURL);
postMethod.execute(new HttpState(), connection);
InputStream response = postMethod.getResponseBodyAsStream();
Log.d("MyLogger", response.toString());
SAXParserFactory spf = SAXParserFactory.newInstance();
SAXParser sp = spf.newSAXParser();
XMLReader xmlReader = sp.getXMLReader();
ExampleHandler exampleHandler = new ExampleHandler();
xmlReader.setContentHandler(exampleHandler);
xmlReader.parse(new InputSource(response));
ParsedExampleDataSet parsedExampleDataSet =
exampleHandler.getParsedData();
tv.setText(parsedExampleDataSet.toString());
}catch(Exception e){
tv.setText("Error: " + e.getMessage());
Log.e(DEBUG_TAG, "ParsingXMLError", e);
}
this.setContentView(tv);
}
}
i got response from that Specified URL....
Thanks
