# Usage of Blog Repository

Now that we have all the necessary pieces to implement offline support, we can finally use them in the `MainActivity`.

Start by creating a `BlogRepository` object in the `onCreate` method *(1).* 

In the `OnRefreshListener`, we are going to call the `loadDataFromNetwork` method *(2)*. 

At the very end of the `onCreate` method, when everything is initialized, we can load data from the database *(3)* and launch loading data from the internet *(4)*. Because loading data from the database is very fast and loading data from the internet is slow, we will see cached data until the data from the internet is loaded.

Apply what you’ve learned about a Repository pattern to build offline support in this lesson.
