android - Making AsyncTask Static (Having Issues, code provided) -

i need know how start asynctask in original activity service that activity starts. fetches music , plays in service , want grab next song after has completed right here:

mediaplayer.setoncompletionlistener(new mediaplayer.oncompletionlistener()      {                    public void oncompletion(mediaplayer mp)          {                            if (mainmenu.radioflag == 1) {                 // start new asynctask             } else {             stopself();             }         }                }); 

down below asynctask, in radio.class. not know how make static references radio.this , getting errors on startservice(i) , stopservice(i). appreciate help, thanks.

private class loadlist extends asynctask<string, userrecord, jsonarray> {      string result = null;     inputstream = null;     stringbuilder sb = null;     jsonarray jarray;      @override     protected void oncancelled() {         toast toast = toast.maketext(getapplicationcontext(), "loading failed, trying again", toast.length_long);

you don't want make asynctask static if could. each instance 1 shot , can never run again.

it seems have fair bit of communication between activity , service. in such situation, should binding service activity. you'll have easy channel calling methods , forth, or can set message , handler channels if want things asynchronously.
