CC @nesquena @timothy1ee

Private repo cuz of all the twitter creds. This is for Cory Dominguez, I offer you a early preview, everything is complete with the exception of the tweet getting immediately added to the feed post posting the update. I intend to mix in some sql goodness before it is done but I thought I would touch this issue off.

User Stories:

• User can sign in using OAuth login flow
• User can view last 25 tweets from their home timeline
• User can compose a new tweet
• User can click a “Compose” icon in the Action Bar on the top right
• User will have a Compose view opened
• User can enter a message and hit a button to Post
• User can load more tweets once they reach the bottom

:+1: Nice work overall. A few thoughts:

• Good that you only have a single method used everywhere which sends the timeline API call
• Nice use of Jackson for object mapping and HTML Parsing
• Optional: Consider adding the character count for Compose Activity to limit to 140. See this event handler for more details.

I have provided a detailed Project 3 Feedback Guide here which covers the most common issues with this submitted project. Read through the feedback guide point-by-point to determine how you could improve your submission.

Let us know if you have any other thoughts or questions about this assignment. Hopefully by now you feel pretty comfortable with all the major pieces to basic Android apps (Views, Controllers, Models, Authentication, API Communication, Preferences, ActionBar, et al) and see how they all fit together.

Hey @nesquena @timothy1ee

I gave it an honest try to get the active android sql working, currently I am mired in foreign key constraint exception hell. There just isn't enough documentation and I suspect that active android does not support this much abstraction. If you are inclined you can check it out, I have it in a branch called sqlite.

Shit I just figured it out, if you muck up your models and run the app then you establish the tables and they don't change when you edit the models. I ended up deleting the emulator and making a new one and now everything works fine. Huzzah. This might be worth going in your common problems section.

@corydominguez Does problem #4 capture the issue well?

Problem #4: Using ActiveAndroid, got an error saying that there is no such table. This is because ActiveAndroid only generates the schema if there is no existing database file. In order to "regenerate" the schema after creating a new model, the easiest way is to uninstall the app from the emulator and allow it to be fully re-installed. This is because this clears the database file and triggers ActiveAndroid to recreate the tables based on the annotated models in the project.
