I used the tutorial http://www.c-sharpcorner.com/UploadFile/88b6e5/how-to-call-web-service-in-android-using-soap/ and did some chances that it shoud work for android 4.0.3! But it still doesn't! Can someone post me a correct solution?

You can not access any UI elements in th DoInBackground() method, as it runs on its own thread, not on the UI thread. You should use
txtFar.setText(result.getProperty(0).toString());
and
Toast.makeText(getApplicationContext(), "No Response",Toast.LENGTH_LONG).show();
call in the onPostExecute, or in onProgressChanged() methods.
You are updating UI in the background thread. You have to update UI on the UI thread.
Return result in doInBackground()
In onPostExecute() update ui.
Void onPostExecute(int result)
{
if(result != null)
{
txtFar.setText(result.getProperty(0).toString());
}
else
{
Toast.makeText(getApplicationContext(), "No Response",Toast.LENGTH_LONG).show();
}
}
http://developer.android.com/reference/android/os/AsyncTask.html. Look at the link especially the topic under The 4 steps.
In your Activity.
new SoapRequestTask().execute();//call asyntask from ui.
private class SoapRequestTask extends AsyncTask<Void, Void, Long> {
protected void onPreExecute() {
//display progress dialog
}
protected Long doInBackground(Void... params) {
//make soap request and get result. do not update ui here.
return result;
}
protected void onPostExecute(Long result) {
//dismiss dialog. update ui here.
}
