I know this question has been asked many times but hear me out. I have MainActivity which is a LoginActivity & it uses facebook login and AccountKit From Facebook to login and start next activity which is a ContactsActivity. When i am in ContactsActivity and press back button it takes me to MainActivity but i want to close the application as user has successfully logined in and if the user again opens the app it should open ContactsActivity directly as user has signed in successfully previously.
Problem is when i press Back button in Contacts Activity,it takes me to LoginActivity,i already tried finish() after startActivity(intent) which closes my app and not takes me to ContactsActivity after successfull signin.If i open my app again then it takes me directly to ContactsActivity. I even tried onBackPressed in which i wrote finish but it doesnt work. In Android Manifest also i wrote android:noHistory="true" in MainActivity tag but it doesn't work. Please help
