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 [...]
In this article I revisit (again) the seemingly perennial problem of controls being obscured by the virtual keyboard when it appears. The code related to this article was tested with Delphi Tokyo 10.2.3, however it may work with earlier versions. TL;DR: The demo code is part of, and relies on units from the KastriFree project. [...]
In my last article, I discussed the new requirements for Android apps on Google Play to target Android 8 (API level 26) and higher, and described one possible way of handling permission requests at runtime, as required when targeting Android 6 (API level 23) and higher. In this article, I describe an alternative, and [...]
****IMPORTANT****: Please use the solution presented in my follow-up article at this link, in preference to the one presented here. This article is retained here for reference only. From August 2018, all new apps on Google Play must target Android 8 (API level 26) or higher, and from November 2018, all app updates on [...]
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 This article tackles the problem head-on UPDATE: This article, and the demo for it, has been superceded by this article and the demo associated with it.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, [...]
The recent Delphi 10.2.2 Tokyo release has resulted in a flurry of reports for apps on Android that "hang" when using tab transitions, or when using "wait" animations. This article offers an explanation for the issue, as well as a potential workaround. Update: As per E. Spelt's suggestion on the report, I've modified the [...]
iPhone X has recently been released, and Delphi developers are a little in the dark about how their apps can support the new devices. This article goes some way to make a start in the right direction. Update 2: Delphi Tokyo 10.2.2 now supports the new layout on iPhone X, including launch images, so [...]
This is one CodeRage you won't want to miss. Specifically, because there are some very interesting speakers this year, including Uncle Bob Martin (author of The Clean Coder, and many others) and Steve McConnell (author of Code Complete and Software Project Survival Guide), and some sessions will be live only (i.e. without replay). CodeRage XII [...]
"Slack" is an internet collaboration tool that seems to be gaining popularity pretty quickly. I've been using it for over a year now, and have set up a team for Delphi Worlds.I have channels dedicated to discussing the Kastri Free library, as well as other channels, and just discussing Delphi in general.If you'd like to [...]
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 [...]
