Here's a walkthrough of implemented user stories:
Describe any challenges encountered while building the app.
- I faced some challenges with the reply, retweet, and favorite functionality. Specifically with the reply feature, I had difficulty with having the @ load automatically in the compose activity page. However, I was able to do this by passing extras with the intent and adding parameters to the POST request.
- I also faced some challenges with applying scrolling effects to the toolbar since I got confused with the action bar in the app with adding my own new action bar and toolbar. After running the app, I had two action bars. I realized later on that I had to set the original action bar to no action bar and ensure that the menu items and styling applied to the new toolbar.
