DSE Wizard — A Digital Signage Solution For Android


We delivered an Android mobile app as an assistant for a digital signage software solution to efficiently manage media content on connected screens.


Our client — a global leader in delivering telecommunications and technology solutions — set the challenge for our team to develop a digital signage application and integrate it into the client’s existing software and hardware suite. Digital signage implies using LED and LCD projection, as well as e-paper technology to display digital images, video, web content, weather data, menus, etc. This type of solution is suited well for stadiums, stores, museums, hotels, restaurants, offices, transport terminals, or any other public place, to show wayfinding directions and outdoor advertising, among other functions. The client needed a team of experts who could be in touch 24/7 during the entire digital signage software development process. In addition to meeting qualification requirements, our developers were ready to provide that level of commitment. That became the key factor why the client chose our Android development team for their digital signage project.


The Android mobile application developed by our team became the third integral component of this suite. The main functions of this digital signage app, named DSE Wizard, were the authorization of consoles during their first-time use and their connection to the screens displaying digital signage. When businesses buy consoles distributed by our client, they just need to scan the QR-code appearing on the screen when connecting the console for the first time, then enable WiFi, Bluetooth, and other connectivity services. After that, users can activate their consoles online. There were some additional features of the DSE Wizard app that we implemented: Status check of connected displays. The app sends notifications in case of errors or issues. User profile management. The app allows setting up and connecting multiple screens, monitoring their statuses, locking specific displays, and more. The console app ecosystem maintenance The digital signage suite also featured four Android apps preinstalled on the client’s consoles. Our team was tasked with improving these applications and maintaining their flawless performance as part of the project. These apps included: Launcher — an environment for configuring the console UI, launching the player, and executing commands sent from the admin panel (for example, to upload logs and files, restart the application, install updates, etc.). The Launcher either executed the incoming commands on its own or delegated it to one of the other preinstalled applications, Fota or Executer. Fota — an application for downloading and installing updates for all the console apps, as well as running commands received from the Launcher. Executer — a service application for caching the progress status of each command, recording the results (successful or not), transferring them to the server, and running specific commands received from the Launcher. LED Indicator — a light indicator displaying the hardware status. To extend the functionality of these apps, our Android development team: Added new commands and tasks to the Launcher app Extended the range of tasks and commands taken up by the Executor app Enhanced the update installation process for the Fota app
