I try an example from a video for http client and i want to load data from that site but when i run it it does not show anything , here is my getmethod code:
public class GetMethodEx {
public String getInternetData() throws Exception{
BufferedReader in= null;
String data=null;
try{
HttpClient client = new DefaultHttpClient();
URI website = new URI("http://www.mybringback.com");
HttpGet request = new HttpGet();
request.setURI(website);
HttpResponse response = client.execute(request);
in = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
StringBuffer sb = new StringBuffer("");
String l = "";
String nl= System.getProperty("line.seperator");
while((l=in.readLine()) != null)
{
sb.append(l+nl);
}
in.close();
data = sb.toString();
return data;
}finally{
if(in != null){
try{
in.close();
return data;
}catch(Exception e)
{
e.getStackTrace();
}
}
}
}
}
and here is main code :
TextView httpStuff;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.httpex);
httpStuff=(TextView)findViewById(R.id.tvhttp);
GetMethodEx test = new GetMethodEx();
String returned;
try {
returned = test.getInternetData();
httpStuff.setText(returned);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
and this is my logcat:
