DroidKernel

Welcome to DroidKernel — a meetup community for people who don’t just use Android, but want to understand it, build on it, and push it further.
I’m Yosuke (English name: John, nickname: Obsidian)— an Android developer and long-time Linux user. Over the past few years, my work and personal projects have been driven by one obsession: Android as a real, hackable, engineering playground. Android isn’t just an app platform — it’s a Linux-based system with layers worth exploring, from UI and APIs down to the “kernel-ish” side of how devices actually behave.
DroidKernel is an independent Android + Linux studio and project universe, built around practical learning, shipping real things, and sharing deep technical knowledge in a friendly, welcoming space. I also publish books about Android/Linux (rooting workflows, tooling, and hands-on labs), and this meetup is the community side of that mission: a place to learn together, build together, and level up.

### What DroidKernel meetups are like

Depending on the session, we’ll do things like:

• Android app development meetups (beginner → intermediate), with real-world patterns and workflows
• Workshops and mini-labs focused on Android internals (ADB, debugging, logs, system behavior, performance)
• Linux-for-Android developers topics (shell power, tooling, automation, dev environments)
• Rooting / custom ROM culture (responsibly) — discussed as learning and engineering, not shady hacking
• Occasional project nights where we build something together (apps, utilities, CLI tools, scripts)

### Who should join

You’re welcome here if you are:

• learning Android development from scratch
• already building apps and want a stronger foundation
• a Pixel/Android power user curious about the system under the hood
• a Linux user who wants to connect your skills to Android
• someone who simply loves Google’s OS and open-source tech culture

No elitism, no gatekeeping. If you’re curious and willing to learn, you belong here.
DroidKernel is where Android enthusiasts become builders — and builders become specialists.
