This app is a tutorial on how to use the Retrofit library to make HTTP requests within an Android App. To do this, we request upcoming launches from the SpaceX API.

Read about the SpaceX API here: https://github.com/r-spacex/SpaceX-API

There are several TODO items throughout the code. Complete the TODO items to make the app functional.

To see the solution code, see the solution branch.

Steps to finish the app:

1. Add the INTERNET permission in AndroidManifest.xml.
2. Create a Retrofit service to get upcoming launches in LaunchesService.kt.
3. Set the Base URL for the API.
4. Build the retrofit client and set properties.
5. Assign call to the return of getUpcomingLaunches in LaunchesService.
6. Set launchesRetriever to the LaunchesRetriever class instead of null.
7. Call getUpcomingLaunches on launchesRetriever, passing the callback function as a parameter.
8. Set the type within Response to the type we expect the API to return.

Final Result

The final app will look like this:
