Parse for Corona SDK

This sample project shows how to communicate with Parse.com, a back-end data service, from a Corona SDK app. You should be able to adapt it to your needs with minimal changes. See main.lua for a barebones UI. To use the parse.lua module, add: 1 local Parse = require("parse") to your main project file and refer to functions as shown in main.lua. You'll want to use SDK build 2012.782 or later, for... More...

Streaming "News Ticker" (Twitter Feed or Online Text File)

I wrote the following bit of code for an app I'm working on where I wanted to have a "news ticker" scroll along the bottom of the home screen that I could change remotely. I also briefly considered streaming the most recent tweets from a Twitter account - so I'm including that code as well. See the commented-out text below for notes on how to change the ticker text or Twitter feed that displays. If you copy this... More...

Facebook helper/support module

This library creates a wrapper around the Corona SDK Facebook API support. Using this library will streamline your Facebook client logic and make it easier to debug and to catch/handle errors (well, it did for my anyway, YMMV). The biggest feature is probably that it supports Facebook functionality in the simulator (for most things). More...

Super Simple IAP in 1 Line

I use this in pretty much all my projects, and it works perfectly. I stripped out some of my own custom code, and left it with all the essentials that you need. Please let me know if it works for you. When you try to fetch the price of an item, it seems to be a hit or miss for me. I've tried multiple devices, and I'm not sure why it only works sometimes. Apples IAP servers are pretty bad, and there's lots of small... More...

Ad Mediator for Corona®

Ad Mediator for Corona is a client-side ad mediation module very much like AdWhirl. It supports admob, inmobi, inneractive, herewead and house ads out of the box and can be extended easily by using a simple plugin framework. Ad Mediator is using providers' http api interface to request and fetch ad banners. By using this method, it knows whether there aren't any ads from a provider and able to select next available...

RSS Parser Take Two

I've replaced the old RSS parser with this one..... Please use this one instead. This project includes a very basic RSS parser which requires the use of Jonathan Beebee's XML parser (included). It should process any well formed, valid RSS 2.0 feed. I still need to update the atom.lua parser for ATOM 1.0 feeds and it will be added here when it's ready. Please note, you will need daily build 721 if you want to use... More...

Flickr Photo Browser

Awhile ago, I was approached to do a custom app for someone. The app itself is finished (not published yet) and in the process of creating it I thought it would be a good idea to publish the source for the dynamic image slider control I created. Well, not content with just publishing a simple control, I decided to create an entire demonstration app to see it in action. The Flickr Photo Browser is the result of this... More...

Check Network Connection with Callback function table

My app has some social elements to it. Primarily, posting to Facebook and tweeting. When the user touches either action, I first wanted to check their Internet connection and wait on the result. Thanks Lerg for help. To use, you pass several arguments: The URL to check, and four function callbacks for unreachable, reachable via Wifi, via Cell, and viaOther. The calling code looks like this for example: 1 DataNet.... More...

Simple Loading Message

This piece of code displays a simple animated loading message, "Loading...", while asynchronously downloading a file. Animated feedback is critical for apps on mobile devices, especially when performing network operations. Users tend to wait a lot longer when they have some kind of feedback.

Text-to-speech using network.download

As discussed here, Google provides an unofficial text-to-speech (TTS) API. It's quite easy to implement in Corona by modifying the Ansca-provided async network code. It could be useful for app accessibility or to have a synthesized voice speak when buttons are pressed, for example. More...

Async/Sync State Management For Debug

I got really excited when I read about Niels Async HTTP workaround using Web Pop Ups. I realised early on the difficulty of trying to debug code which couldn't run within the Corona Simulator which doesn't support Web Pop Ups. I wrote some code which which can switch between Sync for local debug, and Async for deployment to the phone. In order to maintain the event flow I had to build in an onComplete event for Sync...

corona-async-http

Currently (November 3, 2010), the Corona SDK only support synchronous http requests, meaning your app blocks while the http request is in flight. Even sound playback comes to a grinding halt. While we wait for Corona to officially support async http, I have created a workaround based on webpopups and AJAX. Usage is as follows: 1 2 3 4 5 6 7 8 local async_http = require("async_http") local... More...
