SimpleTweet is an android app that allows a user to view his Twitter timeline and post a new tweet. The app utilizes Twitter REST API.

Time spent: 12 hours spent in total

The following required functionality is completed:

• 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

The following optional features are implemented:

• User can pull down to refresh tweets timeline
• 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 detail view 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 take favorite (and unfavorite) or reweet actions on a tweet
• User can see embedded image media within a tweet on list or detail view.

The following bonus features are implemented:

• User can view more tweets as they scroll with infinite pagination
• Compose tweet functionality is build using modal overlay
• Use Parcelable instead of Serializable using the popular Parceler library.
• Replace all icon drawables and other static image assets with vector drawables where appropriate.
• User can click a link within a tweet body on tweet details view. The click will launch the web browser with relevant page opened.
• User can view following / followers list through any profile they view.
• User can see embedded image media within the tweet detail view
• Use the popular ButterKnife annotation library to reduce view boilerplate.
• On the Twitter timeline, leverage the CoordinatorLayout to apply scrolling behavior that hides / shows the toolbar.
• 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.

Here's a walkthrough of implemented user stories:

The URL for the tweet images comes from using the meta tags of web pages which the tweet links to. If no appropriate meta tag is present, no image is displayed with the tweet. Images can load in after the RecyclerView Viewholder has been bound, and the RecyclerView is notified of the index in the dataset which has changed, which triggers the image to be loaded.
