I mentioned some other payment options in https://coderanch.com/t/611538/Android/Mobile/SMS-SMS-ticket-system-simular#2793681, but those don't support the in-app aspect of several small items being sold to the same customer, AFAIK, it's more about a fixed price for the app. So you'd have to implement all that, regardless of payment method.

It's harder to get people to switch to a different app (some will do, but you'll lose some in the process), and fewer people check out apps that cost money from the start. There's a clear trend away from paid apps towards in-app purchases.

You want an answer in seconds, so you're going to have to multiply feet by seconds/feet (yes, the dimensions work just like their values do in arithmetic). So suppose your track length is 18 feet and the speed is 2 feet/second. To get seconds/feet you take the reciprocal, so that's 0.5 seconds/feet. Multiplying that by 18 feet gives you 9 seconds for the length of the animation.
Now, that's assuming you want your animation to take the same amount of time that the box actually takes to move along the conveyor. You might want to speed it up, because having it take 9 seconds to cross a small computer monitor might not produce the right effect. However I'd leave that part aside for now and just work on simulating the box's travel in real time. Inserting a speed-up (or slow-down) factor could be done later without too much difficulty.

No, it should be Metformin HCL, Januvia, Abilify.
Without the quotes.
Too bad you can't use opencsv or Apache commons CSV.
