Notes

To compile and run this app, you will need to edit the Configuration.getInstagramClientId() method to return a valid client id. Otherwise, the app will crash upon boot.

• Ran into a lot of issues trying to dynamically scale the TextView icons to match the height, eventually bailing on that.
• Had some issues with the relative layout not cascading below/above to elements which were left/right of another element.

Open-source libraries used

• Android Async HTTP - Simple asynchronous HTTP requests with JSON parsing
• Picasso - Image loading and caching library for Android
