Modern Android App Development with Java

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 `loadDataFromNetwork` method *(2)*. 

At the very end of the `onCreate` method, when everything is initialized, we can load data from database *(3)* and then 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 data from the internet is loaded.

This lesson will provide instructions on how the application should function when not connected to a network.
