I have a C# Web Service but I can’t consume it on Android. Follows the Code of android and the LogCat.

//----------------------------- Conectando a Base WS

class asynProjeto extends AsyncTask<String,String,String>{

    @Override
    protected void onPreExecute(){
        super.onPreExecute();
        Log.i("AsyncTask", "onPreExecute");
        dialogo = new ProgressDialog(MainActivity.this);
        dialogo.setMessage("Carregando");
        dialogo.setIndeterminate(false);
        dialogo.setCancelable(false);
        dialogo.show();

    }

    @Override
    protected void onPostExecute(String s){

        //super.onPostExecute(s);
        dialogo.dismiss();
        if(s.equals("ok")){
            carregarHello();
        }else {
            Log.e("Script", "Deu Errado:" + s);
        }
        }

    @Override
    protected String doInBackground(String... strings){


        if (Hello()){
            return "Ok";
        }else{
            return "erro";
        }
    }

And that’s the exception:

c# android json

  • Dude, try directing to the part of code you think is the problem...

  • The URL you are using (http://localhost:2749/Service.asmx?WSDL) is the address of description web service (WSDL), not the service itself (which should be the same URL, without the ?WSDL).

  • I do not understand the negativity in the question of the guy... ta missing a little quality and perception on the part of those who want to answer... take a look at my answer and see if it helped!

Android SDK does not give the javax.microedition.io preview. Take a look at Package Index

This is missing this past as I realized in the error:

Caused by: java.lang.Noclassdeffounderror: Failed Resolution of: Ljavax/microedition/io/Connector; at org.ksoap2.transport.Serviceconnectionmidp.(Unknown Source)

I believe Voce has to download the ksoap2 package: ksoap2-android-Assembly-2.4-jar-with-dependencies.jar

NOTE: Always check the latest version of ksoap2.
