Image capturing is no fun without the ability to share images; for example, on Facebook. We will be using the Facebook SDK for that.

Challenge! If you are building an app running on a Parse backend, as we did in Chapter 2, Applications with a Cloud-based Backend, there is no need for that, as the Facebook SDK is already in there. If you want, you can combine the recipes from Chapter 2, Applications with a Cloud-based Backend with this one, and create a real cool app real quick!

Getting ready

For this recipe, you need to have the previous recipe completed successfully and you need to have a real Android device (or a virtual one, but this will require some additional steps).

You also need to have a Facebook account, or you can create one just for testing purposes.

How to do it...

Let's take a look at how we can share our sepia captured image on Facebook:

1. Get the code from the previous recipe. Open the build.gradle file in the app folder. Add a new dependency to the dependencies section...
