Getting started with developing applications for a mobile platform can be a challenging task, especially when it comes to building and testing the application on the mobile device itself.
The Librem 5 makes its application development workflow extremely simple.
The “quick start” video below that I made for the Librem 5 developers documentation demonstrates how quickly you can get up and running with making your own GTK applications on a Librem 5.
In this video, I have attached a Librem 5 to an external keyboard, mouse and monitor through a USB-C hub, and I use GNOME Builder to quickly create a new GTK application project, build it and run it on both the big desktop monitor and the small mobile screen with just a drag and drop across the screens.
Yes, I do all that with the computing power of the Librem 5 only! There are no special effects nor a hidden desktop computer. I even did the screencast recording with an external device so it shows the real speed of the Librem 5 when driving a 32″ Full HD monitor.
