Answer 1

At the time of login successfull put this code:

prefs = getSharedPreferences("logindetail", 0);
                        SharedPreferences.Editor edit = prefs.edit();
                        edit.putString("userLoginStatus", "yes");
                        edit.commit();

At the time of logout use this:

prefs = getSharedPreferences("logindetail", 0);
SharedPreferences.Editor edit = prefs.edit();
                                edit.clear();
                                edit.commit();

And at the time of checking if user is login or not use below code:

 Loginprefs = getApplicationContext().getSharedPreferences("logindetail", 0);
            userLoginStatus = Loginprefs.getString("userLoginStatus", null);
if(userLoginStatus.tostring().equals("yes")){
    //the user is login
}else{
    //user is logout
}

Hope this helps you
