Every now and then there's a post (on Stack Overflow, Delphi Praxis, Facebook etc) asking about developing cross-platform (usually specifically mobile) apps with Delphi, for example the "current state" of the product and whether there's anything they should be aware of. This article details some of the things to be aware of when choosing Delphi. [...]
An enquiry I had from a Hans Jakobsen of EarMaster (brilliant music teaching software for PC, Mac, iPad and iPhone) recently was regarding an apparent "lag" for the OnMouseDown event for controls near the edge of the screen on devices with later versions of iOS. This article poses a workaround for the problem. A [...]
Previously, I have written two articles on monitoring location changes: one for iOS, and one for Android. This article and the related demo brings everything up-to-date and merges support for both operating systems. STTP (Straight To The Point - I'm coining an acronym to replace TLDR) If you're just after the demo, you may find [...]
The requirement for macOS apps to be notarized has thrown a few challenges, one of them being that developers are having trouble with apps that use Indy components with SSL. This article describes how to overcome that issue. Rather than dive headlong into working out why the notarized app would not work, I decided to [...]
Before the release of Delphi 10.3.2, Embarcadero released a patch for including FCM (Firebase Cloud Messaging) for Android in your apps, and now that support is included in Delphi 10.3.2. This article describes how to include support for iOS in FCM. UPDATE: With many thanks to Antonello Carlomagno, the iOS implementation now has been [...]
A little over a year ago, I posted a two part article about integrating Firebase Cloud Messaging in your Delphi mobile apps. This time, it's a single part article because much of the work is done for you, or is simplified. The code in this article was built and tested using an install of [...]
Nearly 5 years ago I wrote an article for checking whether a mobile device has an internet connection. This article revisits that solution, dropping the "less-used" functionality, however it also gains an important feature. The code and demo for this article was written and tested on Delphi Tokyo 10.2.3, however it should work on earlier [...]
Monitoring location updates on Android in a consistent fashion (e.g in a service, and while the screen is locked) can be quite a challenge. This article tackles the problem head-on UPDATE: This article, and the demo for it, has been superceded by this article and the demo associated with it. Please refer to that, [...]
Developing software with Delphi is easy regardless of "cross-platformness", relatively speaking, in comparison to other tools I've used, however this article shows how insanely easy it can be to put together an application that runs on iOS, Android, Windows and MacOS. UPDATE: Developer Jerry Dodge has alerted me to this project of his, called [...]
This is Part 2 of a 2-part article on incorporating support for FCM in your Delphi apps for Android and iOS, and this part covers implementation on iOS. Issues with later versions of the Firebase SDK: For those who are having compile issues with later versions of the SDK, I'm working on resolving the [...]
