How can i create own "online" private data, and connect it to my android db app?

I have an android application that includes many persons objects. Any person have first name, last name and sentence about him.

But i have something like 3500 persons.

I created a SQLite db for my app, and i want that in the first time that user use my app, he will get all the persons to his db.

One of the options is to write all persons in my application, and load this information to the db in the first time that the user open my app, but it is a bad idea.

So, i heard about storing my information somewhere in the internet (online DB, own domain, etc.), but i really dont know what i should and how to do this.

The perpose is that every user will load this information once.

Thanks!
