From d7b16dd2a56035b2feec9f39d6d461fd551317eb Mon Sep 17 00:00:00 2001 From: Matt Pietal Date: Mon, 4 Oct 2021 15:33:14 -0400 Subject: [DO NOT MERGE] Controls - Do not recreate intent Recreating the control's intent in SystemUI can be exploited to launch Intent's with SystemUI's privileges, rather than what is limited to the application. Use the fillInIntent parameter to supply additional parameters to the application.
