Postmates Android API Wrapper
NOTE: Yondon and I built the iOS wrapper @ https://github.com/yondonfu/ios-postmates and it's available on CocoaPods.
Classes you should use for API: PostmatesAPI.java, Delivery.java, and DeliveryQuote.java
TestCallback,java exists only to make outputting chunks of json data easier when I was making the wrapper. You can customize your callbacks for each api call so that the response can be converted to an object of your choice: JSONObject, String, etc.
MainActivity.java serves no purpose than to test the API with random parameters.
HAVE FUN SPREADING POSTMATES!
