User Stories

The following required functionality is completed:

• User can sign in to Twitter using OAuth login
• User can view tweets from their home timeline
  • User is displayed the username, name, and body for each tweet
  • User is displayed the relative timestamp for each tweet "8m", "7h"
• User can compose and post a new tweet
  • User can click a “Compose” icon in the Action Bar on the top right
  • User can then enter a new tweet and post this to Twitter
  • User is taken back to home timeline with new tweet visible in timeline
  • Newly created tweet should be manually inserted into the timeline and not rely on a full refresh
• User can see a counter with total number of characters left for tweet on compose tweet page
• User can pull down to refresh tweets timeline
• User can see embedded image media within a tweet on list or detail view.

The following optional features are implemented:

• User is using "Twitter branded" colors and styles
• User sees an indeterminate progress indicator when any background or network task is happening
• User can select "reply" from home timeline to respond to a tweet
  • User that wrote the original tweet is automatically "@" replied in compose
• User can tap a tweet to open a detailed tweet view
  • User can see embedded image media on a recycler view
  • User can take favorite (and unfavorite) or retweet actions on a tweet
• User can view more tweets as they scroll with infinite pagination
• Compose tweet functionality is built using modal overlay
• User can click a link within a tweet body on tweet details view. The click will launch the web browser with relevant page opened.
• Replace all icon drawables and other static image assets with vector drawables where appropriate.
• User can view following / followers list through any profile they view (with TabLayout, PageFragments, RecyclerView)
• Use the View Binding library to reduce view boilerplate.
• On the Twitter timeline, apply scrolling effects such as hiding/showing the toolbar by implementing CoordinatorLayout.
• User can open the twitter app offline and see last loaded tweets. Persisted in SQLite tweets are refreshed on every application launch. While "live data" is displayed when app can get it from Twitter API, it is also saved for use in offline mode.

The following additional features are implemented:

• User can view a profile's name, banner, profile picture, bio, followers and following count
• User can view the favorite and retweet counts for each tweet on the home feed

Notes

Some challenges I faced were with the additional/optional stories, particularly displaying the followers/following users and replying to a tweet. With followers/following users, I used a TabLayout and PageFragments which I were new to me and required much debugging. Replying to a tweet challenged me, as I was not certain how to start the Compose Activity for a result when the reply icon on the tweet was clicked in the recycler view.
