• There is a back ground service for fetching twits and storing it in database
• There is use of OAuth for authentication
• Notification Manager is used for notifying users about newer twits
• Battery Drain is monitored and Twitter Service is closed to help save battery, and when battery is charged then again Twitter Service is started. (Yet to be implemented- Coming soon)
• In UI side we use shapes and drawable states for background and button images
