From 667d8ea8fd4bda35e8888792d2b6c055fdb4be18 Mon Sep 17 00:00:00 2001 From: Jacopo Mondi Date: Fri, 10 May 2019 17:40:02 +0200 Subject: android: hal: Add Camera3 HAL Add libcamera Android Camera HALv3 implementation. The initial camera HAL implementation supports the LIMITED hardware level and uses statically defined metadata and camera characteristics. Add a build option named 'android' and adjust the build system to selectively compile the Android camera HAL and link it against the required Android libraries.
