For Raspberry Pi 4 Model B and Compute Module 4 with 2, 4, or 8 GB of RAM, as well as for the Raspberry Pi 400 all-in-one, an unofficial build of the experimental branch of the LineageOS 19.0 firmware, based on the Android 12 platform, has been created. The source code for the firmware is available on GitHub. To use Google services and applications, the OpenGApps package can be installed, but its proper functioning is not guaranteed, as support for Android 12 in OpenGApps is still under development.
The builds support graphics acceleration (V3D, OpenGL, Vulkan, featuring the latest release Mesa 21.2.5), audio subsystem (Audio DAC, output via HDMI, 3.5mm, USB, Bluetooth), Bluetooth, WiFi (including hotspot mode), GPIO, GPS (via external USB module U-Blox 7), Ethernet, HDMI, I2C, sensors (accelerometer, gyroscope, magnetometer, temperature, pressure, humidity), SPI, touch screen control, USB (keyboard, mouse, storage), USB-C (ADB, MTP, PTP, USB tethering). Support for cameras and hardware video encoding/decoding is currently absent.
It is worth noting the update to the Android 11 environment for various models of Orange Pi boards, Raspberry Pi 4, Pinephone, and the Pinetab tablet, developed by the GloDroid project. The GloDroid edition is based on the code of the mobile platform Android 11 from the AOSP (Android Open Source Project) repository and focuses on supporting devices based on Allwinner processors and Broadcom platforms. The project aims to adhere as closely as possible to the original version of Android available in the AOSP repository and uses only open drivers, including drivers for GPU and VPU. Ready builds based on the new GloDroid 0.7 release are still in the process of being formed, but all necessary components for self-assembly are available.
