New Factorial Calculator

Inspired from Project Euler, Factorial Calculator can calculate 10000! and above in very short time. This app uses completely difference algorithm (logic) to find the factorial compared to usual algorithm used to calculate small factorials.

It also shows the number of digits in the factorial along with the sum of individual digits. In the More activity, the number of individual digits is shown. All the tasks are done using LoaderCallbacks.

It was fun to implement and learn about background threading and parallelism. Don't forget to rate the app. :)
