Java for Android Call getPackageName() from within an AsyncTask -

i working on android app using inappbilling. moved following code main activity asynctask, recommended google:

class getitemlist extends asynctask<integer, integer, long> {  iinappbillingservice mservice;  serviceconnection mserviceconn = new serviceconnection() {    @override    public void onservicedisconnected(componentname name) {        mservice = null;    }     @override    public void onserviceconnected(componentname name,       ibinder service) {        mservice = iinappbillingservice.stub.asinterface(service);    } };  @override protected long doinbackground(integer... params) {     arraylist<string> skulist = new arraylist<string> ();     skulist.add("i001");     skulist.add("i002");     bundle queryskus = new bundle();     queryskus.putstringarraylist("item_id_list", skulist);     bundle skudetails = null;     try {         skudetails = mservice.getskudetails(3, getpackagename(), "inapp", queryskus);         int response = skudetails.getint("response_code");         if (response == 0) {            arraylist<string> responselist               = skudetails.getstringarraylist("details_list");            (string thisresponse : responselist) {               jsonobject object;               object = new jsonobject(thisresponse);               string sku = object.getstring("productid");               string price = object.getstring("price");               string mpremiumupgradeprice;               string mgasprice;             if (sku.equals("i001")) mpremiumupgradeprice = price;               else if (sku.equals("i002")) mgasprice = price;            }         }     } catch (remoteexception e) {         // todo auto-generated catch block         log.d("synch billing", "error remote: " + e.getmessage());         e.printstacktrace();     }     catch (jsonexception e) {         // todo auto-generated catch block         log.d("synch billing", "error json: " + e.getmessage());         e.printstacktrace();     }     return null; } 

}

my problem call getpackagename() (the first line of try block) giving error, "the method getpackagename() undefined task getitemlist." how call getpackagename() within asynctask? i've tried getcontextwrapper.getpackagename(), getapplicationcontext.getpackagename(), , getresources.getpackagename().

add constructor getitemlist accepts packagename , assigns private field. use in mservice.getskudetails().

and when instantiate getitemlist in activity pass value returned getpackagename() getitemlist constructor.
