New requirements[edit | edit source]

Kernel requirements[edit | edit source]

Android 12, SDK31 raises the bar for board support platform to mandatorily support eBPF in kernels. This means, most of the EOL platforms, which are unsupported by MediaTek ALPS or Qualcomm CodeAurora Forum such as 3.18; 4.4 and etc. are left unbootable.

HAL Requirements[edit | edit source]

The android.system.*HAL Name*.keystore has been upstreamed to version 2.0, leaving most of the compiled builds for old devices unbootable due to unsuccesful /userdata decryption.

Qualcomm targets are mandated to upstream their target Audio HALs to version 7.0.

Vendor test suite regulations[edit | edit source]

This is the first build, where "VNDK Lite" targets have been removed, leaving out the full requirement to ship target with full VNDK implementation.

New features[edit | edit source]

Haptics[edit | edit source]

Android 12 extends the Vibrator HAL functions by adding dynamic feedback and actuator effects. The HapticGenerator effects for AudioFX HAL now can manage haptic effects on output sound.

Quickstep/SystemUI[edit | edit source]

Quickstep now supports icon-alike opening animations for widgets.

BT Stack[edit | edit source]

The user can now control Bluetooth permissions for pairing/A2DP/connection.

Camera2 Updates[edit | edit source]

Camera2API and CameraX now supports Quad/Nona/Hexa-bayer cameras and full output for them.
