Fragment and factory method
Static factory methods allow us to initialize and setup a new Fragment without having to call its constructor and additional setter methods. Providing static factory methods for your fragments is good practice because it encapsulates and abstracts the steps required to setup the object from the client. http://www.androiddesignpatterns.com/2012/05/using-newinstance-to-instantiate.html

Android perform action when Curren time is match to entered time(got from json)
I don't think it is necessary to check if the given time is equal to the current time. Instead when you get your JSON, make an alarm on the time of the JSON. Then show a notification when the alarm goes off. Android will automatically check if the alarm time (so the JSON time) is equal to the current time. If you make an alarm and notification it will work even if your application is not running.
