How to call multiple web service methods in android. I make web service in asp.net.
In android I call my web method in AsyncTask. on PostExecute() I write this code

protected void onPreExecute() 
{
	super.onPreExecute();
	callmethod("http://tempuri.org/getOffer","getOffer");
	//callmethod("http://tempuri.org/getWeapon","getWeapon");
	result = (SoapObject)envelope.bodyIn;
}

I also call web method getWeapon but then how i find result that which method is called?
