Ich bin verwirrt, wo ich meine AsynTask nennen sollte? Um acct.getEmail() zu bekommen, muss ich mich anrufen handleSigninResult(), aber wenn ich dort anrufen AsynTask bekommen jedes Mal aufgerufen, wenn ich die App öffne. Eigentlich muss ich AsynTask nur zum Zeitpunkt der ersten Anmeldung anrufen ... was zu tun, irgendwelche Ideen ... ????
fetchUserdataServerAsync mfetchUserdataServerAsync= new fetchUserdataServerAsync(acct.getEmail());
mfetchUserdataServerAsync.execute();
