From edac95e737d65466d52e77be5ebef7e378f756ef Mon Sep 17 00:00:00 2001 From: Siarhei Vishniakou Date: Mon, 31 Jul 2017 20:33:41 -0700 Subject: [PATCH] DO NOT MERGE Remove window obscurement information. If ACTION_OUTSIDE_EVENTS contain information about whether the touch is obscured, then a pattern of invisible, untouchable, unfocusable SYSTEM_ALERT_WINDOWS can be placed across the screen to determine approximate locations of touch events without the user knowing.
