Android : One Android App which can work as native for diffrent events

I want to develop an Android app which will show information (Date, Venue, Sessions, Speakers etc..) about different Events from a web service, but i wanted it to feel native, like if Event 1 user run this app they should not know about Event 2, they just see there Event details.

Example

Like Facebook, they identify you by your login and show you your profile.

Here are possible solutions

1. Offer user to type Event Code on App Launch & remember it


2. Auth User and Show related event


3. Create Native app for every Event

and I want to Have only one app, which will not required any Input from user and show there event. Is it possible to do, please help

or is there any way to generate apk dynamically with different event ids
