android - Facebook SDK(4.x): AccessToken.getCurrentAccessToken() returns null during run and not null in debug mode -
method one:in case set place holder objects current accesstoken , profile
facebooksdk.sdkinitialize(getapplicationcontext()); // initialize sdk before executing other operations, // especially, if you're using facebook ui elements. accesstoken accesstoken = accesstoken.getcurrentaccesstoken(); profile profile = profile.getcurrentprofile(); //attempts recognize if user has logged in before if(accesstoken !=null){ if(profile !=null) { //set user parceable //start intent next activity //in final code intent 3 tabbed activity (faves, nearby, specials) //for navigating nearby intent intent = new intent(splash.this, nearbyplacesholder.class); startactivity(intent); finish(); } else{ } } method two: use if statement check if getcurrentaccesstoken() == null , if set boolean islogged in false. if getcurrentaccesstoken() == null condition returns set isloggedin true , perform if statement on isloggedin.
the problem inside of debug mode code works perfectly, when run it, no go, app stays login activity , requires user perform login. doesn't prompt actual login overlays spinning circle , continues. profile , accesstoken there.
instead of trying retrieve profile again, after login facebook save info want, including fb id, sqlite db. no issues anymore.
old:
as of right code catching isloggedin 95% of time. not 100% tho. think timing issue, wish there way make sure isloggedin() doesn't called until facbook resources ready.
