Instagram (Parsetagram) is a photo sharing app using Parse as its backend.
Time spent: 17 hours spent in total. (5 for required stories, 12 for extra features)
The following required functionality is completed:
- User sees app icon in home screen.
- User can sign up to create a new account using Parse authentication
- User can log in to his or her account
- The current signed in user is persisted across app restarts
- User can log out of his or her account
- User can take a photo, add a caption, and post it to "Instagram"
- User can view the last 20 posts submitted to "Instagram"
- User can pull to refresh the last 20 posts submitted to "Instagram"
- User can tap a post to go to a Post Details activity, which includes timestamp and caption.
- User sees app icon in home screen
The following stretch features are implemented:
- Style the login page to look like the real Instagram login page.
- Style the feed to look like the real Instagram feed.
- User can load more posts once he or she reaches the bottom of the feed using endless scrolling.
- User should switch between different tabs using fragments and a Bottom Navigation View.
- Feed Tab (to view all posts from all users)
- Capture Tab (to make a new post using the Camera and Photo Gallery)
- Profile Tab (to view only the current user's posts, in a grid)
- Show the username and creation time for each post
- User Profiles:
- Allow the logged in user to add a profile photo
- Display the profile photo with each post
- Tapping on a post's username or profile photo goes to that user's profile page
- User Profile shows posts in a grid
- After the user submits a new post, show an indeterminate progress bar while the post is being uploaded to Parse
- User can comment on a post and see all comments for each post in the post details screen.
- User can like a post and see number of likes for each post in the post details screen.
The following additional features are implemented:
- User can change to night mode! (Thanks to Ainsley, my manager, for this great guide: https://www.geeksforgeeks.org/how-to-implement-dark-night-mode-in-android-app/)
- User can create a post from image on the gallery
Please list two areas of the assignment you'd like to discuss further with your peers during the next class (examples include better ways to implement something, how to extend your app in certain ways, etc):
- Ways to persist like and comment interactions between Detail view and main feed withouth doing requests (maybe with intents)
- How did they handle the database relationship between comments, posts and likes
Here's a walkthrough of implemented user stories:
- Be able to see and create comment and like interactions from main feed (since fragments are hosted on activities, we cannot use intents to pass info between them. In that case, when a post is liked from detail view, maybe we can use Bundle and call PostFragment from DetailActivity passing the modified post as an argument)
- Add number of posts in the user profile
List an 3rd party libraries, icons, graphics, or other assets you used in your app.
- Android Async Http Client - networking library
Describe any challenges encountered while building the app.
