<p>This is a review of the current state of Free and Open Source Software on Mobile devices. Mobile computing continues to be one of the most conspicuous and rapidly evolving software ecosystems ever, and open source software is at the heart of it - from the Linux kernel, the tooling, languages and libraries needed to write apps, through to devices that run a completely open source stack</p>
<p>We will talk about the changes in the way Google releases AOSP code and how that affects developers of custom ROMs and off-the-shelf devices. We will talk about developments in fully Android-free platforms, and we will talk about hardware support, drawing on voices from across the FOSS mobile community.</p>
<p>The presentation will be of interest to those already involved in the FOSS and mobile communities, and also to those who are just interested to get an overview of the landscape.</p>

<p>Android support for RISC-V is advancing rapidly, and this talk delivers an in-depth technical update on the open-source AOSP porting effort. We will walk through the current status of AOSP on RISC-V platforms, including ART/LLVM, Bionic, HAL and vendor-interface development, and compatibility work for emerging RISC-V SoCs. The session will examine the key engineering challenges encountered along the way—such as JIT/AOT differences on RISC-V, graphics-stack porting (Mesa, DRM/KMS, GPU ...

<p>The Android Open Source Project (AOSP) is more than just the yearly and now half-yearly releases of the Android platform source code. It consists of 3000+ git repositories, 1500+ repo XML manifests, and 1.8+TB of (compressed) source code data.</p> <p>In this talk I want to give a detailed tour of the AOSP releases, the code, and everything that can be found in the AOSP repositories: How are the <code>_rXXX</code> releases assembled? And why do the git tags sometimes go backward? Where do I ...

<p>Building Android is notoriously slow and resource-hungry. Even on high-end hardware, a full AOSP build can take hours, and each release continues to grow by ~10–20%, amplifying compile times and storage pressure. For anyone maintaining custom ROMs, vendor trees, or downstream forks, faster builds are not just nice to have: regulation requiring shipping fixes faster makes build performance a core productivity issue.</p> <p>Over the years, the Android ecosystem has tried to keep pace with ...

<p>Securely signing Android releases, while being a critical process and operation for every AOSP-based project, has been lacking in comprehensive documentation, especially for building a production-grade and enterprise-level signing infrastructure. This talk presents our experience in designing and implementing a Hardware Security Module (HSM)-based signing solution for CalyxOS that ensures transparency and operational practicality while upholding security standards widely endorsed by security ...

<p>NewPipe is a widely used <strong>FOSS Android app</strong> that provides privacy-respecting access to <strong>YouTube, PeerTube, and other streaming services</strong>. It can search, view channels, play videos, listen to playlists, download media, and more.</p> <p>Developing an application with so many distinct features often involves compromises or <strong>feature trade-offs</strong>. During the talk, we'll explain how TeamNewPipe takes these decisions together with the community. In recent ...
