From 288d5550cca373358485498e4a1909f58006c9e6 Mon Sep 17 00:00:00 2001 From: Tony Huang Date: Thu, 28 Jul 2022 08:57:40 +0000 Subject: [PATCH] Improve enter split transition Improve enter split transition by two part changes. 1. Enter split with resizing animation: We directly show split but no animation before, it might looks bad to user because UI change too many things in few frames. 2. Fix flicker cause by black screen when split active: When we start intent on side stage task, the top split root task will go to top and current top one task will be set as invisible then cause black screen due to split root task is full screen. Solve this by use new wct api setForceTranslucent to make split root task as translucent when split inactive. We need to reset it when split active otherwise it cause flicker when back to home. Except above change, we also need to set side stage bounds to area outside of screen otherwise it still cause flicker because it will show a flash of shadow when launch intent on side stage. This solution should be removed after shell transition fully landing because in shell transition we could make those transitions be done in one transition.
