From 4f2ea10357be90b703c1e459fe3a0d346cd0c97d Mon Sep 17 00:00:00 2001 From: Vishnu Nair Date: Thu, 2 Sep 2021 09:52:48 -0700 Subject: SurfaceControl: Add setDropInputMode api Introduces an API to drop input events on this SurfaceControl. This policy will be inherited by its children. The caller must hold the ACCESS_SURFACE_FLINGER permission. Options include: ALL: SurfaceControl and its children will not receive any input regardless of whether it has a valid input channel. OBSCURED: SurfaceControl and its children will not receive any input if the layer is obscured, cropped by its parent or translucent. These policies are used to enable features that allow for a less trusted interaction model between apps. See the bug for more details.
