java - Android Simple HTTP Request? -

-

i have code android application i'm trying create interact php website. have android.permission.internet permission activated , keeps creating toast says "error." instead of contents of website. here java file:

package com.http.request;  import java.io.ioexception;  import org.apache.http.httpresponse; import org.apache.http.httpstatus; import org.apache.http.client.httpclient; import org.apache.http.client.methods.httppost; import org.apache.http.impl.client.defaulthttpclient; import org.apache.http.util.entityutils;  import android.app.activity; import android.os.bundle; import android.widget.toast;  public class httprequestactivity extends activity {     /** called when activity first created. */      private string dohttprequest(string url){         string results = "error";         try         {             httpclient hc = new defaulthttpclient();             httppost post = new httppost(url);              httpresponse rp = hc.execute(post);              if(rp.getstatusline().getstatuscode() == httpstatus.sc_ok)             {                 results = entityutils.tostring(rp.getentity());             }         }catch(ioexception e){             e.printstacktrace();         }         return results;     }      @override     public void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.main);          string results = dohttprequest("http://www.yahoo.com");         toast.maketext(getapplicationcontext(), results, toast.length_long).show();     } }

i check make sure that,

  1. if there exception being thrown, investigate causing ioexception
  2. your server potentially returning non-200 response code.

put in breakpoints , see whats happening there. bet on response code.
