Please list two areas of the assignment you'd like to discuss further with your peers during the next class (examples include better ways to implement something, how to extend your app in certain ways, etc):
- Databases and querys
- Fragments
Here's a walkthrough of implemented user stories:
List an 3rd party libraries, icons, graphics, or other assets you used in your app.
- Android Async Http Client - networking library
Describe any challenges encountered while building the app.
- My main challenge while building this app was implementing the like and comment features. I was initially unsure how to store the information (ArrayLists through the Post or User class or as separate classes in the database). After discussing with my manager, I decided that Like and Comment should each be separate classes in the database since there is a many-to-many relationship between users and posts. For the like and comment features, in the database, I have pointers to the user who took the action as well as the post where the action occurred. I also had some difficulties querying the correct posts or getting the correct count for the number of likes and comments. I resolved this issue by learning more about querys and various methods I can call such as whereEqualTo.
