There is a Spanish blog post up with two videos demonstrating how to build your own client for sending push notifications to Android and IOS apps using Delphi XE7 Firemonkey. Basically both Google and Apple have APIs for accepting push notifications which get sent to your Android and IOS apps. These videos show how to create applications in Delphi that can send the push notifications through the platform API instead of relying on some third party service to do it for you (and paying for that service). The videos and blog post are in Spanish but the code itself is just normal Object Pascal and looks pretty easy to understand. The demos show a VCL app but it could just as easily be built in an FMX app (with Appmethod for example). Even if your apps aren’t built with Delphi you can send push notifications to them from these applications. I found the blog post over on Humphrey: Kim Hyun – Soo’s blog about it.
