Android 15 source code pushed to AOSP

Android 15 AOSP

Android 15 will only become available on supported Pixel devices in the coming weeks, and on other phones in the next couple of months, but Google has already pushed Android 15 source code to AOSP (the Android Open-Source Project). We already documented some of the main changes in Android 15 when the first developer preview was released in February 2024. These included improvements related to privacy and security, the addition of the partial screen-sharing feature, camera and audio improvements, and some performance optimizations. You should be able to retrieve the Android 15 source code from AOSP with the following commands:

Android 15 is based on Linux 6.6 LTS, so Android 15 SDKs from silicon vendors will likely be offered with Linux 6.6, although I can see Linux 6.1 is also an option. It’s also possible to browse Android 15 source code without downloading several GB of data to your […]

Android 13 is already working on Qualcomm Robotics RB3 and RB5 platforms

Qualcomm Robotics RB5 Android 13

Qualcomm Robotics RB3 (aka DragonBoard 845c) and Robotics RB5 boards can already support Android 13, just a few days after the source code was pushed to AOSP (Android Open Source Project). Once upon a time (i.e. a few years ago), it would have taken weeks, and more likely months, to port the latest version of Android (AOSP) to a specific single board computer. But thanks to initiatives such as Project Treble, Android reference boards such as DragonBoard 845c (RB3), HiKey 960, Khadas VIM3, and Qualcomm Robotics Board RB5 can now get the latest version of Android up and running in a matter of days. Android 13 was released on August 15, and Linaro wrote about RB3 and RB5 support on August 18, and while Linaro engineers collaborated with Google engineers before the AOSP, it is still an impressive feat. Amit Pundir, Linaro Engineer, explains how this was made possible: Over […]

Android 13 released, source code pushed to AOSP

Android 13 release

Android 13 has just been released rolling out to Google Pixel devices initially, and later to other devices from Samsung Galaxy, Asus, HMD (Nokia phones), iQOO, Motorola, OnePlus, Oppo, Realme, Sharp, Sony, Tecno, vivo, Xiaomi and more. Google also pushed Android 13 source code to AOSP (The Android Open Source Project). Most of the changes to the new version of the Android operating system were introduced with the first Android 13 developer preview – released in February 2022 – adding privacy, security, and productivity improvements, and even some hidden gems such as virtualization enabling Pixel 6 to run Linux and Windows 11, although the feature was mostly implemented for security reasons and running third-party code such as DRM or crypto outside of the Android OS. Other notable features added since then include Spatial Audio on headphones that enable head tracking, Bluetooth LE audio support, HDR video support on third-party camera […]

Android RISC-V progress update, emulator support, and roadmap to 2023

Android 12 RISC-V

We’ve first covered Alibaba T-Head work on Android 10 for RISC-V in January 2021, and later that year they started selling the T-Head RVB-ICE dual-core RISC-V board with GPU for software development. The company has now provided an update for Android 12 RISC-V port, instructions to build Android RISC-V to run it in an emulator,  as well as a 2022-2023 roadmap. Alibaba T-head is working on hardware platforms, which appears to be similar to T-Head RVB-ICE board, with the following minimal specifications: CPU – At least Dual-core XuanTie C910 (rv64imafdcv) processor GPU – Compatible with OpenGL ES and OpenCL VPU – HW Video/Picture codec Neural Network Accelerator System Memory – 4GB or more DDR Memory Display – MIPI/HDMI Audio – Multi-Channel Audio output & input Camera – ISP with support for multiple MIPI CSI lanes USB interface(s) They built upon the work done on Android 10 to add support for […]

Android 12 on Raspberry Pi 4 – (Almost) everything works

Android 12 Raspberry Pi 4

Android 12 (AOSP) source code was released last month, and a developer took the opportunity to port Android 12 to the Raspberry Pi 4 single board computer and derivatives. More specifically, KonstaT created an unofficial build of LineageOS 19.0 for Raspberry Pi 4, Raspberry Pi 400 keyboard PC, and Compute Module 4 working on systems with at least 2GB of RAM. While it’s reserved for advanced users, the Android 12 build appears to work pretty well with most features supported including: Video HDMI display including CEC Touchscreen/multi-touch (USB touchscreens, Waveshare SPI touchscreens) Hardware-accelerated graphics (V3D, OpenGL & Vulkan) Audio HDMI, 3.5mm jack, USB microphones, Bluetooth speakers/headphones Audio DACs such as Hifiberry DAC+ Connectivity Ethernet WiFi including tethering Bluetooth including Bluetooth tethering GPS using external USB modules USB tested with USB mouse, keyboard, storage, etc… USB-C: ADB, MTP, PTP, USB tethering I/Os (GPIO, I2C, SPI) tested with Remote controls via external […]

Android 12 source code AOSP

Google has now pushed Android 12 source code to AOSP (Android Open Source Project), after introducing Android 12 new features and the developer preview in February, and the first Android 12 Beta in May. The latest version of the mobile operating system should become available on recent Google Pixel phones in the next few weeks, followed by phones from Samsung, OnePlus, Oppo, Realme, Tecno, Vivo, and Xiaomi. You can download the code with the following command :

Eventually, there should be an Android 12 tag in the manifest similar to android-12.0.0.0_r1. But that still means developers can start retrieving the source code to adapt the operating system to their needs, for example, to implement support for single board computers or TV boxes that do not use Android TV OS. The release notes for the source code list of the changes made to Android 12 OS including: Support for Android […]
