Join us for a special edition of the Android Budapest meetup in May! This time, we’re collaborating with mDevCamp, the Prague-based mobile dev conference. You will have an opportunity to get a free ticket to the conference! Before the summer break, you’ll have another opportunity to learn more about Android and meet fellow mobile devs! We’ll have two great talks to set the tone of the evening - this time you’ll hear from two organizers of our meetup, on the topics of Kotlin Multiplatform and screen recording on Android. **📜 Schedule:** **18:00 - 18:30: Gathering and socializing** **18:30 - 19:15: First talk** **19:15 - 19:45: Break** **19:45 - 20:15: Second talk** **20:15 - : More socializing!** **—** **🔷 Going Multiplatform with Your Android App - Márton Braun, JetBrains** Existing Android apps are in a great position to expand into Kotlin Multiplatform: you might already be using patterns, libraries, and APIs that work on more platforms than just Android. With Compose Multiplatform, you can build an app with a fully shared Kotlin codebase, targeting iOS, desktop, and even the web! In this talk, we’ll look at how you can migrate an existing Android app to multiplatform. As this can be a significant engineering effort for an existing, well-established app, we’ll also discuss how to plan and organize the required changes, and how to adopt KMP incrementally across your codebase without disrupting day-to-day development. **🔷 When MediaProjection Isn't Enough - Building a Custom In-App Session Recorder - István Juhos, Spoke** Debugging user issues gets so much easier when you can see exactly what they experienced. While off-the-shelf solutions exist to integrate screen recording into our apps, they didn't give us the quality, flexibility, or control we needed. So, our team built our own native, in-app session recording tool for Android. In this talk, I'll share why we decided to go in-house, how we tackled the technical and UX hurdles along the way, and what we learned about recording high-quality video and audio data. We'll dive into tricky bits like exploring - and discarding - the MediaProjection API, handling codecs and muxers across devices, designing recording controls that stay out of the user's way, playing back recordings, and managing background uploads without draining your users' battery or patience. — 🏢🍴 Thanks to [Supercharge](https://supercharge.io/careers) for the drinks and hosting us in their lovely office, and the organizers of [mDevCamp](https://mdevcamp.eu) for the food and discounted conference tickets! 🚪 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 or submit at [https://androidbudapest.com/talkidea](https://androidbudapest.com/talkidea)!**

Practice Buddhist meditation in the middle of Budapest! The meditation is suitable for beginners. Each regular meditation is guided and begins with a short introduction. (all together is about 30-40 minutes) Our regular Buddhist meditations have proven popular with people who want to integrate authentic Buddhist methods into their daily lives. For the modern lay person who is juggling work, relationships, and an active role in society, we teach a meditation that is easy to learn, and profound and powerful for experienced practitioners. The meditation originates from the Karma Kagyu tradition of Tibetan Buddhism. It has a cumulative effect on mind, leading to greater clarity and calmness. Fearlessness, joy, and active compassion are the result of regular practice of Buddhist meditation. * Do I need any special clothing? No special clothing needed. * Does the attendance cost anything? No, the meditation is free.

Gyere és folytasd az olvasmányod a csendes könyvklubunkon a Fővárosi Szabó Ervin Könyvtárban: hozd magaddal az aktuális könyvedet, merülj el benne egy órácskát, majd oszd meg velünk, amit olvastál. 🗺 **Hogyan találsz meg minket:** A Központi Könyvtár fő épületének **Metszéspont** termében leszünk (régi tanulótér): a könyvtárba belépve haladj tovább a liftekig, de mielőtt elérnéd őket, fordulj balra a mosdók irányába. Az ott található lépcsőkön gyere fel fél emeletet. 💡 Az eseményen való részvételhez nem szükséges könyvtári regisztráció vagy beiratkozás, csak jelezd, hogy a Csendes Könyvklubra jössz. 🥤 **Étel-ital:** Kérünk, zárható üvegben hozz magaddal innivalót, ha az esemény alatt megszomjaznál. Másból inni, valamint a teremben enni nem lehet, de az épület átriumában üzemel kávézó. 🕑 **A menetrend (változás!):** 17:30–18:00 – Bemutakozókör: mit fogsz olvasni? 18:00–18:45 – Csendes olvasás 18:45–19:30 – Kiscsoportos beszélgetés a könyvekről (opcionális) 🍹 Az esemény után igény szerinti **afterezés** a [Prága Kávéház és Sörözőben](https://pragakavezo.hu/) (Baross u 8.), hogy ne csak könyvekről beszélgessünk! Ha csak erre jönnél, írj üzenetet, hogy ne kerüljük el egymást. 🇭🇺 Fontos: Ez egy teljesen **magyar nyelvű esemény**. A bemutatkozó kör az elején és a kötetlen beszélgetés a végén is magyarul zajlik. Az olvasás csendje persze mindenkié, így nyugodtan hozhatsz bármilyen nyelvű könyvet. **✨** **Önkéntes hozzájárulás** A Meetup-felület fenntartására elfogadunk adományokat, hogy eseményeket az eddig megszokott színvonalon és nyitott emberek között tarthassuk.

Customer identity resolution becomes increasingly complex as organizations scale across multiple systems, regions, and data formats. Traditional rule-based approaches often fail to keep up with data variability, require constant manual tuning, and struggle with real-time processing needs. This session presents a practical approach to building a scalable identity resolution pipeline using AWS services and modern AI techniques. The architecture combines data ingestion through Amazon S3 and AWS Glue, transformation pipelines using Spark on EMR, and machine learning models deployed via SageMaker for entity matching and standardization. Graph-based relationship modeling is implemented using Amazon Neptune to improve resolution accuracy by incorporating household and shared attribute context. We will walk through how machine learning models can be used for name and address normalization, how intelligent blocking strategies improve matching efficiency, and how feedback loops can be introduced to continuously improve accuracy. The session also highlights how serverless components such as AWS Lambda can be used for orchestration and real-time processing. **SPEAKER BIO** Mosaic Syed is a Senior Data Engineering and Cloud Solutions Architect with over 20 years of experience designing and delivering scalable, secure, and high-performance data solutions across global enterprise environments. https://www.linkedin.com/in/mosaic-basha-syed-92300856 **CALL FOR SPEAKERS** Learn more: [https://www.awscolumbus.com/get-involved/](https://www.awscolumbus.com/get-involved/) **THANK YOU** *VEEAM* for hosting our meetup!

Practical AI for Power BI Developers A year ago, “agentic AI” was mostly hype for Power BI teams. Today, it deserves your undivided attention. For Power BI pros, there is now a real opportunity to reduce repetitive development work, accelerate delivery, and help developers do more, but only when strong DataOps practices are in place to make AI workflows effective. This session is a no-nonsense introduction to effective AI patterns for Power BI and Fabric development. Along the way, we will make sense of the growing pile of terminology, including skills, plugins, hooks, and MCP. You will see examples of how modern AI tooling can help with development tasks across Power BI and Fabric, along with the prerequisites, guardrails, and DataOps principles needed to use it responsibly. Whether you're burned out on AI hype or already using Copilot CLI daily, this session will show you the foundations that are finally making AI-assisted development genuinely useful.
