What Will iPhone5 Mean To Corona SDK Developers

Posted by & filed under Corona Geek.


According to the rumor sites iPhone 5, or whatever it will be officially called, is set to be announced soon with a taller screen that will support another row of icons. For consumers this will mean they’ll have access to more apps on their home screen and more viewable real-estate for playing games and getting things done, but what will it mean to mobile developers who use the Corona SDK to produce their cross platform mobile apps? As the MacRumors mock-up video below shows, it probably won’t mean much initially. Existing Corona apps will likely function as they do today, with the exception that they’ll be displayed in the center of the screen with black letterbox bars on either side of the app. That’s good

Amazon Now Accepts Promotional Images

Posted by & filed under Corona Geek.


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 are looking for extra ways to market your mobile apps, check out the full details on the Amazon Mobile App Distribution Blog. Charles

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 think that’s what they officially call it), and Apple’s App Store and each of them already support international sales.
