and [Handling countdown timers in recyclerview - android] (https://stackoverflow.com/questions/38241539/handling-countdown-timers-in-recyclerview-android)
The aim of the project is to showcase how to handle multiple timer inside the recyclerview and how to clean up the resource.
Instead of CountdownTimer/TimerTask app performs count down operation using Runnable and handler.
Motivation of the application is to have individual timer for each row, however recycle the timer as same logic as view recycling, so that there won't be peak memory usage and leading to impact on performance.
