This week was exciting because, instead of using an external API, we were able to create our own backend for an Instagram-like app in both Android and iOS. We used Back4App to get and post user and post data. This required use of the Parse library in both projects.

In the Android version of the application, I used Parse to enable a user to sign up for an account and to login. I also implemented persistent login and the ability for the user’s to pull up the system’s camera to take a picture, add a caption, and post it to the backend.

In the iOS version, I did the same thing, but also implemented the ability to view the last 20 posts (something that I will get to in the Android version next week).
