From fdf749b2c6b8bac20ce4065b4d4686cb700fad58 Mon Sep 17 00:00:00 2001 From: Eino-Ville Talvala Date: Thu, 14 May 2020 15:20:10 -0700 Subject: [PATCH] Camera: Extend FEATURE_CAMERA_CONCURRENT to old API levels Since running the front and back camera at the same time has been possible since forever, there's no reason devices on older API levels can't declare the FEATURE_CAMERA_CONCURRENT flag, even with the new query APIs not present. Explicitly document that the flag can be set on API level 29 or earlier, and what it means.
