                 if(response!=0)
                 {

Maybe the Android class AsyncTask can be helpfull.

make the WebService request on doInBackground method and show the gallery on postExecute method.

more info: AsyncTask on Android doc

Update: Replace the onclick method content with:

AsyncTask<String, Void, Integer> task = new AsyncTask<String, Void, Integer>(){

    @Override
    protected Integer doInBackground(String... params) {


        // TODO Auto-generated method stub
        //request code for Webservice
        SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
        //sending the username to the webservice
        request.addProperty("kullaniciAdi",username.getText().toString());
        //sending the password to the webservice
        request.addProperty("password",password.getText().toString());
        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
        envelope.dotNet = true;
        //Putting the request in an envelope
        envelope.setOutputSoapObject(request);
        HttpTransportSE transport = new HttpTransportSE(SERVICEURL);
        try
        {
             transport.call("http://tempuri.org/"+METHOD_NAME, envelope);
             //getting the response from the webservice
             return (Integer) envelope.getResponse();
        }//end of try 
        catch(Exception exception)
        {
            exception.printStackTrace();
        }//end of catch
        return 0;
    }


    protected void onPostExecute(Integer result) {
        if(result!=0)
        {
           openGaleryVideo();
        }//end of if statement
    };
};

But I need to use AsnycTask while uploading too. Can I use this more than once in the app? — answer88, Jul 12 '12 at 12:55
what about the arguments? what should I use as arguments in this situation? — answer88, Jul 12 '12 at 12:58
In the example code of the question the Ws returns an Integer, so for example AsyncTask, the String are params to the doInBackground method and the Integer the response of this method and the param of the onPostExecute method. — sabadow, Jul 12 '12 at 13:01
could you plesa show me in the code or corrected version? Because I am a bit confused. @sabadow — answer88, Jul 12 '12 at 13:08
Sorry but it does not connect anymore to the webservice too. @sabadow — answer88, Jul 12 '12 at 13:23
