private static final String Soap_Action = "http://tempuri.org/UploadFile";
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
handlerobj.post(runnableobj);
}
private Handler handlerobj = new Handler();
private Runnable runnableobj = new Runnable() {
public void run() {
