Last night I received an email from the Amazon Mobile App Distribution Team. They wanted to let me know that as a Mobile App Distribution Developer, I can now add promotional images to my apps. Apparently their internal marketing team uses promotional images in featured placements to highlight apps, and they'll be using these "creative assets" in more places, so they want you to participate. If you're a mobile developer who publishes their apps in the Amazon Marketplace, you'll need to use the dimensions 1024 x 500 pixels for your promotional images and provide them in PNG or JPG format. If you...

Hello all you groovy mobile developers! Today Amazon announced support for international sales in the U.K., Germany, Italy, and Spain. Since I haven't published an app in the Amazon Appstore yet, I wasn't even aware that these weren't already options, so tada! I am a registered developer though, so Amazon sent all their developers an email announcing the news. In the email they said, "You now have the ability to select the countries where you would like your apps to be sold and can set your list prices by marketplace." So far, I've submitted apps to the Google Play Marketplace (I...

When I first started using the Corona SDK in December of last year, I was eager to learn as much as possible about what the SDK could do and where it was headed. When a Dallas Corona SDK developers meetup was scheduled in the Dallas area, I jumped at the opportunity to talk with other developers and meet Walter Luh, Co-Founder of the company. During that meetup I met a lot of talented developers who were able to discuss the Corona SDK in-depth including Dr. Brian Burton, author of the book "Mobile App Development With Corona". As a college professor and app...

Recently I came across a great bit of Corona SDK sample code written by Adam Smith at iNSERT.CODE that really intrigued me. The code simulates the buoyancy of objects in water and it's very well written and extremely well commented. The code is a great example of how much you can accomplish with a relatively small amount of code using the Corona SDK. Even if you don't need to include this feature in your project it's worth exploring. So, I decided to reach out to the Adam to see if he would answer a few questions about his background and how he came to...

A friend of mine sent me a link to this article on Android fragmentation. The article includes a pretty interesting info-graphic that shows 3,997 different Android devices. These are the 3,997 different Android devices that OpenSignalMaps users experienced the app with. How many devices do iOS developers have to worry about?...
