the php json this

{"cities":[{"name":"aitor"}]}

and logcat:

12-02 04:24:01.492: e/webservice(2190): end of input @ character 0 of  

thanks

you in mainactivity line

httpresponse execute = cliente.execute(httpget); 

is throwing networkonmainthreadexception can check using (in first try catch well)

catch (exception e) {         // todo: handle exception          log.e("errormsg", e.tostring();     } 

so instead of using asynctaskloader better use asynctask.

public class mainactivity extends activity {  textview tv1;  @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_main);     tv1 = (textview) findviewbyid(r.id.text);     exe exe = new exe();     try {         uri uri = new uri("http://comupunt.esy.es/cities.php");     } catch (urisyntaxexception e) {         // todo auto-generated catch block         e.printstacktrace();     }     exe.execute();  }  class exe extends asynctask<url, string, string> {      string entrada = "";      @override     protected string doinbackground(url... url) {          string resultado = "";          try {             defaulthttpclient cliente = new defaulthttpclient();              defaulthttpclient httpclient = new defaulthttpclient();             uri uri = new uri("http://comupunt.esy.es/cities.php");             httpget http = new httpget(uri);               httpresponse execute = cliente.execute(http);              inputstream contenido = execute.getentity().getcontent();              bufferedreader buffer = new bufferedreader(                     new inputstreamreader(contenido));              string s = "";              while ((s = buffer.readline()) != null) {                 resultado += s;             }             jsonobject object = new jsonobject(resultado);             log.e("webservice1", object.tostring());             jsonarray jarray = object.getjsonarray("cities");              (int = 0; < jarray.length(); i++) {                 jsonobject jobject = jarray.getjsonobject(i);                 string name = jobject.getstring("name");                 entrada = name;              }          } catch (exception e) {             // todo: handle exception             log.e("webservice", e.getmessage());         }          return entrada;      }       @override     protected void onpostexecute(string res) {          tv1.settext(entrada);     } } 

}
