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):
- Fragments
- Uploading an image from gallery
Here's a walkthrough of implemented user stories:
User persistence and logout
GIF created with LICEcap.
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.
This app was pretty fun to make, this time I completed most of the optional user stories and I am pretty happy with the end result. I finally was able to understand fragments properly and implemented them nicely in the app. The main challenge of this assignment was understanding how to use Parse, it was a completely new concept and I was able to understand it thanks to Codepath's documentation and some extra help from stackoverflow. During this assignment I never really got stuck other than when trying to allow the user to upload a profile picture from the phone's gallery, this took some reasearch in Google and I ended up adapting a random code I found online to my needs, I ended up getting a URI from the gallery, then transforming it to an array of bytes using a function I found online and finally transforming it again into a Parse File. Overall it was a fun assignment.
