Project 2 - Simple-Tweet

Simple-Tweet 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: 5 hours spent in total

User Stories

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 is using "Twitter branded" colors and styles
• User can click links in tweets launch the web browser
• User can select "reply" from detail view to respond to a tweet
• The "Compose" action is moved to a FloatingActionButton instead of on the AppBar
• Compose tweet functionality is build using modal overlay
• Use Parcelable instead of Serializable using the popular Parceler library.
• 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.
• When a user leaves the compose view without publishing and there is existing text, prompt to save or delete the draft. If saved, the draft should then be persisted to disk and can later be resumed from the compose view.
• Enable your app to receive implicit intents from other apps. When a link is shared from a web browser, it should pre-fill the text and title of the web page when composing a tweet.

The following additional features are implemented:

• Used Snackbars to show alerts
• Used AlertDialog in order to ask the user in case he/she/they wants to save it as a draft

Notes

Describe any challenges encountered while building the app.

I had to research and debug in order to find the specific problem when reading/writing the saved tweets as Android requires more permissions for security purposes.

I took some time figuring out how to create a AlertDialog and still going back afterward. I fixed this by creating the AlertDialog window inside the onBackPressed overriden function.

Due to my current lack of time, I could not create all the exciting stretch stories and find the Twitter resources in order to make my Twitter clone more similar as the original application, but will definitely polish this application during my free time as I had a lot of fun creating it!
