android - Webサービスに接続した後、ギャラリーを開くことができませんでした

Question

Webサービスに接続できますが、Webサービスに接続した後、ギャラリーを開いてそこからビデオを選択します。問題がどこにあるのか教えていただけませんか。これが私のコードです：

Android クラスの AsyncTask が役立つかもしれません。

doInBackground メソッドで WebService リクエストを作成し、postExecute メソッドでギャラリーを表示します。

詳細: Android ドキュメントの AsyncTask

更新: onclick メソッドの内容を次のように置き換えます。

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
    };
};
