For Raspberry PI 4 Model B and Compute Module 4 C 2, 4 or 8 GB RAM, as well as for the monoblock Raspberry PI 400, formed informal assembly of the experimental firmware branch lineageos 19.0 , based on the Android platform 12. The source texts of the firmware are distributed on github .
You can install the OpenGapps , but its correct work is not guaranteed, because the support of Android 12 in OpenGapps is still at the stage Development .
The assemblies are supported by speeding graphics (V3D, OpenGL, VULKAN, the fresh release of MESA 21.2.5 is integrated), the audio subsystem (Audio DAC, output via HDMI, 3.5mm, USB, Bluetooth), Bluetooth, WiFi (including in Access point mode), GPIO, GPS (via an external USB module U-BLOX 7), Ethernet, HDMI, I2C, Sensors (accelerometer, gyroscope, magnetometer, temperature, pressure, humidity), SPI, control via touch screen, USB ( Keyboard, Mouse, Drives), USB-C (ADB, MTP, PTP, USB Tethering). While there is no camera support and hardware coding / video decoding.
Separately, you can noted update Android 11 environment for various models of Orange Pi, Raspberry PI 4 , Pinephone phone and Pinetab tablet developed by the project glodroid . The Glodroid editor is based on the Android 11 mobile platform code from the AOSP (Android Open Source Project) and focuses on supporting allwinner processors and platforms Broadcom. The project, as far as possible, is trying to stick to the original Android version available in the AOSP repository and uses only open drivers, including drivers for GPU and VPUs. Finished builds based on the new release Glodroid 0.7 are still in the formation process, but all the components needed for self-assembly .
