i don't see in code onactivityresult method. required sdk workflow.
you need add mainactivity:
@override protected void onactivityresult(int requestcode, int resultcode, intent data) { super.onactivityresult(requestcode, resultcode, data); callbackmanager.onactivityresult(requestcode, resultcode, data); } cause:
every activity , fragment integrate facebooksdk login or share should forward onactivityresult callbackmanager.
you can find in documentation here.
