A sample Instagram viewer project for CodePath

This is an Android demo application for displaying the latest popular posts from Instagram.

The following required functionality is completed:

• User can scroll through current popular photos from Instagram
• For each photo displayed, user can see the following details: - Graphic, Caption, Username - Optional) relative timestamp, like count, user profile image

The following optional features are implemented:

• Add pull-to-refresh for popular stream with SwipeRefreshLayout
• Show latest comment for each photo (bonus: show last 2 comments: 2nd comment not shown due to layout size)
• Display each user profile image using a RoundedImageView
• Display a nice default placeholder graphic for each image during loading (read more about Picasso: used Glide)
• Improve the user interface through styling and coloring
• Allow user to view all comments for an image within a separate activity or dialog fragment
• Allow video posts to be played in full-screen using the VideoView

The following additional features are implemented:

• Added a splash screen
• Added activity transition animations
• Added a floating action bar button for refreshing the view
• Added logic to start pre-loading the content in the splash page
• The list of popular pictures refreshes onResume if the previous load is over 20 seconds ago
• The video restarts if the orientation changes in the middle of playback
• Added a “Play” button to watch video directly from the popular pictures activity

Walkthrough of all user stories:

• Please note that video playback doesn’t work in the emulator, but works in an physical device and hence is not part of the video walkthrough.
