We're back for 2026, and looking forward to seeing you at our February event, where you can learn more about Android and meet fellow mobile devs in person! As usual, we’ll have two great talks to set the tone of the evening, both from returning speakers at our meetup, exploring build configuration testing and code generation. **📜 Schedule:** 18:00 - 18:30: Gathering and socializing 18:30 - 19:05: First talk 19:05 - 19:30: Break 19:30 - 20:05: Second talk 20:05 - : More socializing! — **🔷 Gradle Testing: Unlocking TestKit for Developers - Tom Koptel** Testing custom Gradle plugins is a critical step in ensuring their reliability, especially when developing for Android projects. This talk will focus on leveraging the Gradle TestKit framework to set up robust testing environments for custom plugins. Attendees will learn how to configure their projects effectively, enabling seamless plugin testing and integration. Key topics include: * Project Setup for Plugin Testing: Laying the groundwork for a Gradle plugin project with proper dependencies and configurations tailored for Android development. * Using Gradle TestKit: A deep dive into functional testing with TestKit, including creating isolated test environments using GradleRunner and managing temporary directories for test builds. * Testing Against Multiple Android Gradle Plugin (AGP) Versions: Techniques to ensure compatibility across AGP versions by dynamically injecting dependencies during tests. * Advanced Testing Tools and Techniques: Exploring tools like Jacoco for code coverage metrics and live debugging of code under test. **🔷 Compile-time code generation with Kotlin Symbol Processing - Lajos Nyéki** In this talk, we will explore the advantages of compile-time code generation and how it can streamline development workflows by reducing boilerplate, improving performance and catching errors early. We’ll dive into Kotlin Symbol Processing (KSP), highlighting its modern approach compared to the older Kotlin Annotation Processing Tool (KAPT), and discuss why KSP is becoming the preferred choice for many Kotlin developers. To ground these concepts, we’ll walk through a real-world case study demonstrating how compile-time code generation with KSP can be applied to solve practical problems. — 🏢🍴 Thanks to [EPAM](https://careers.epam.hu/) for hosting us in their office, and keeping us fed and hydrated throughout the event! 🚪 **Doors open at 18:00** and the first talk starts at 18:30! 🗓️ The event is free but requires registration, so **please RSVP** here and don’t forget to update your response if it changes! 📸 We plan to take photos, so if you would not like to appear on them, please tell one of the organizers! 🎤 We are always looking for new presenters, so if you have an idea for a talk, please reach out to us at [meetup@androidbudapest.com](http://meetup@androidbudapest.com/) or submit at [https://androidbudapest.com/talkidea](https://androidbudapest.com/talkidea)!

**We are back. And by popular demand: We are finally doing this on a Friday!** For Event #4, we’re flipping the script. Forget the best practices. This time, we're focusing on **worst practices.** We’ll dissect real business failures through three lenses: legal, psychological, and marketing. Decisions that looked smart on paper, passed approval, and still detonated. We’ll revisit familiar disasters like **Theranos** and **Fyre Festival**, then go deeper into lesser-known, more uncomfortable cases and even scandals including global brand implosions and local examples like **Shrooly**. **This isn’t about laughing at failure.** It’s about understanding how smart teams convince themselves bad ideas are good ones, and learning how to spot the moment everything starts going wrong. **The Agenda & What You'll Learn** Three angles, one goal: Make sure you don't end up on this list next year. * **17:45:** Arrive, grab a drink (it's Friday!), and connect. * **18:00 – 18:15: How NOT to run your business (legal angle).** We look at the structural red flags that sink ships. From the valuation hallucinations of **WeWork** to the **Honey scam** and local hardware flops like **Shrooly**. We’ll cover how to mismanage cash, ignore the law, and implode your company from the inside out. * **18:15 – 18:30: How NOT to gain customers (marketing angle).** “There’s no such thing as bad publicity” is how this always starts. Then the backlash hits. We’ll break down campaigns that went viral for all the wrong reasons - from **Pepsi and Bumble** to **Bud Light and Apple** \- unpacking how rebrands\, stunts\, and culture\-driven ads cross the line from attention to alienation\, and how brands lose their audience because of some 'viral' ideas\. * **18:30 – 18:35:** **🎁** A super secret surprise * **18:35 – 18:50: How NOT to handle customers (psychological angle).** Users don’t leave when something breaks, instead they leave when something feels off. We’ll explore dark UX patterns, manipulative design, and behavioral shortcuts that quietly cross ethical lines from **friend.com** to platforms that optimized engagement until users turned hostile. This is how loyal users become your loudest critics. * **18:50 – 19:00:** A very special announcement * **19:00 – 20:00:** Genuine networking & conversations with quality food and drinks. * **20:00 onwards:** We are heading to a nearby bar. Since **nobody** has work tomorrow, we expect the conversation to go late. **Who Is This For?** This is for freelancers, digital nomads, and founders in Budapest who want to disaster-proof their work. Join a community of curious, open-minded people for an honest conversation. No corporate fluff, just genuine connections. If you want actionable takeaways on what *not* to do, this is for you. **Location** We'll be hosting at the fantastic **KLUSTER Coworking** space. **The Legal Bit** Our imaginary lawyers (who are currently panicking about this event topic) wanted us to mention that we'll be taking some photos. By attending, you consent to this. Thanks for reading, see you on **the 20th**! Bence & Marguerite & Nándi

Digital products are evolving from “screens” to intelligent partners—services that notice context, anticipate intent, and adapt in real time. That shift is exciting… and risky. How do we design experiences that feel helpful without becoming creepy, confusing, or out of control? Join us at Product Design Talks by Ergomania for: Beyond UX: How Digital Products Become Intelligent Partners **📍 Rudas Bistro, 1013 Budapest, Döbrentei tér 9.** **📅 18 February 2026 \| 🕔 17:00** ⏱ Practical, inspiring knowledge in 2 hours We’ll unpack **Sentient Design** (popularised by Josh Clark): moving beyond rigid self-service flows toward **products** that **respond** **dynamically** to **real-life situations. Think: your banking app surfaces the right action the moment you land in Tokyo** \- currency exchange\, nearby ATMs\, relevant insights\, without you hunting for them\. Programme: **17:00 Welcome reception** **17:20 Talk: When Banking Apps Stop Being Static and Start Noticing Context — [Adam Dragus](https://www.linkedin.com/in/adamdragus/)** **17:45 Panel: [Dr Andras Rung - UX Strategist](https://www.linkedin.com/in/drandrasrung/), [Adam Gyökhegyi](https://www.linkedin.com/in/adamgy/), [Adam Dragus](https://www.linkedin.com/in/adamdragus/), [Gábor Lukács](https://www.linkedin.com/in/gbr-lukacs/)** **18:45 Networking** In the panel we’ll compare approaches teams use today, **discuss when anticipation helps vs. hurts, and how to balance adaptability with clarity**, **trust**, and **user** **control**, especially in regulated products. Bring your questions—there’ll be time for discussion, and you’ll meet like-minded peers over drinks. 🎟 Seats are limited. Register here: [https://productdesigntalks.ergomania.eu/en/events/beyond-ux-how-digital-products-become-intelligent-partners/](https://productdesigntalks.ergomania.eu/en/events/beyond-ux-how-digital-products-become-intelligent-partners/)

We meet at **05:45 AM** (**Gellért Hill**) for a small, low-volume **synthwave / retrowave / ambient** sunrise hang. Coffee or wine in hand, neon-coded accessories welcome, friendships are to be made. This isn’t a party; it’s a shared moment, music, conversation, and Budapest waking up. **Who should join:** Music lovers, sunrise people, photographers, internationals & locals who enjoy calm vibes and good talk. **How it works:** * **RSVP to get the exact pin** (capacity **20**) * **One speaker provided, please don’t bring yours** * 60–90 min flow: ambient → lift at first light * Optional group photo + coffee walk after **Bring:** blanket, coffee/wine, warm layer, subtle 80s/neon touch. **Vibe & etiquette:** quiet & considerate, **leave no trace**, no litter, no drones at dawn, respect neighbors/sleepers. **Lore:** Rumor says the host is a friendly **cyborg** powered by synths and caffeine. Come verify.

**A 2026-os meetup évadot egy AI SEO workshoppal indítjuk: valós projekten, lépésről lépésre vesszük végig az AI Search és SEO folyamatát, gyakorlati, kevésbé ismert tippekkel. Előadó: Papp Gábor (The Pitch).** **Program:** * 17:45 – 18:00: érkezés * 18:05 – 19:30: AI SEO workshop * 19:30 – 19:45: Q&A * 20:00-ig esemény zárás, kötetlen beszélgetés **Regisztráció:** Az eseményen való részvétel ingyenes, de a létszámkorlát miatt regisztrációhoz kötött. Regisztrálni a Meetup felületén tudsz. Az eseményre csak akkor tudjuk biztosítani a belépésed, ha ezt legkésőbb az eseményt megelőző napon éjfélig megteszed. **Egyéb információk:** A terem befogadóképessége 50 fő. Aki RSVP-zik, de nem tud jönni, az legkésőbb 24 órával a meetup kezdése előtt mondja le a részvételi szándékát. Mások elől ne vegyük el a helyet! A meetupot követően az előadások slide-jait mindig a Meetup rendszerén keresztül küldjük ki, így automatikusan megkapja az, aki valóban ott is volt az eseményen. Ez akkor működik, ha nem iratkozol le a hírlevelekről (Meetup szolgálati közlemények). A workshopról és az élő kódolásról nem készül felvétel és nem kerül streamelésre sem. Köszönjük!

Join us for an evening dedicated to the evolving landscape of software engineering. As our tools become more powerful, our focus shifts from simply writing syntax to building architecture and stronger teams. We’ll explore two distinct sides of this evolution: the human side, where **peer and mob programming** foster trust and shared ownership, and the technical side, where **AI agents** allow us to "print code" and one-shot complex features. Whether you are looking to improve "team quality" or manage the "review bottleneck" of AI-driven development, this meetup offers practical insights for every engineer. This English-language event will be held at the **Formlabs Budapest office**, where we'll provide snacks and drinks to fuel conversations. Arrival is from 17:30, Announcements and agenda at 17:55, first presentations will start at 18:00. \-\-\- **Peer Programming to increase "Team Quality"** **with [Nico Riedmann](https://www.linkedin.com/in/nico-riedmann/)** Most engineers are familiar with pair programming. Your team may already encourage it to foster learning or as an alternative to ensuring code quality via pull-request reviews. This talk will show you the impact that collaboratively creating code has on "team quality" rather than just "code quality" - creating opportunities to build trust, increase shared ownership, and define and better understand a shared vision. And if you weren’t convinced before, we’ll end with a few practical tips on getting started with pair and mob-programming. **One-Shotting Features: The Reality of Agentic Workflows** **With [János Molnár](https://www.linkedin.com/in/j%C3%A1nos-moln%C3%A1r-9b582896/)** This talk explores our journey from using AI as a glorified auto-complete to one-shotting complex features. I’ll discuss our team’s evolution from using AI for basic code generation to adopting agentic workflows that shift our focus toward planning and architecture. We’ll explore the benefits of this high-level approach alongside the "review bottleneck" that occurs when AI velocity outpaces human auditing, and how we adapted our processes while releasing and building our Greenhouse project. \-\-\- Come learn and connect with other tech enthusiasts. See you there! You can also find the recordings of previous events on the [@DevBPMeetup YouTube channel](https://www.youtube.com/@DevBPMeetup).

Ez nem előadás, nem panelbeszélgetés és nem agilis best practice-ekről szól. Ez egy kötetlen este, ahol **minden résztvevő hoz egy elcseszett helyzetet – és egy tanulást belőle**. Nincs cégnév, nincs hibáztatás, nincs okoskodás. Csak őszinte történetek, közös nevetés és az a megnyugtató felismerés, hogy nem vagyunk egyedül ezekkel a dilemmákkal. És sör. *Helyszín:* A Grund - Bazsesz terem (az emeleten a csocsó asztal után jobbra) *Időtartam:* 17:30-tól kifulladásig
