thanks for the links...
I'm doing preliminary research on how I can write a native android ordering application, specifically for a restaurant. This app essentially allows people to order food on the go. There are two main concerns that I have.
1. What technology are available to connect the restaurant and their customers to process their order? (for example. customer places/pays for order and the order transaction is sent to the restaurant to process/acknowledge the order.) To my knowledge, SMS is a possibility. Also using the in-app payment from google as mentioned above is another good idea since it has some useful functions already built in.
2. My second concern is implementing a shopping cart to add items to and be able to edit it while also, if possible in android, send it to a server or database(Similar to most e-commerce) and do all the processing there. As of now, I realize the in-app payment from google includes a shopping cart, so this could be a solution but I still need to do more thorough research.
Cheers!
