I improved both the Android and iOS versions of my simple Twitter client this week.
In the Android version, users can now compose and post a new Tweet through a compose button added to the ActionBar. After a user posts a tweet, the timeline is automatically refreshed! I used a library called Parcelable in order to pass information from one Android activity to another. Using Parcelable is more time/memory efficient than the Serializable interface.
On the iOS side, I also implemented the ability for a user to compose and post a Tweet. However, what differed from the Android implementation this week was that I also added the ability to favorite and retweet tweets!
