Answer 1

You can try this

 fun checkLoginInfo(): Boolean{
    val saveLogin = sharedPreferences.getBoolean(SAVE_LOGIN, false)
    return saveLogin
}

 Checks whether the preferences contains a preference. 
 @param(SAVE_LOGIN) key The name of the preference to check.
 @param(false) default
 @return Returns true if the preference exists in the preferences, otherwise false.
