Prime Number Generator for Android
There are a number of things you can do: generate of lists of prime numbers, check if a number is a prime or not, produce random primes for whatever reason you got, or just read and learn a little about the world of prime numbers.
The prime number generator-function produces a list of all the numbers up to a given number of your choice. For really big numbers, this is quite a work intensive task, but it doesn't run on the main thread, so even though it takes a couple of seconds to calculate tens of thousands of prime numbers, it doesn't crash like many other apps of this kind.
In the future this app will also contain a function to do some prime factorization.
