(This cl reverts change-Id: I455edcd17bda83ab51c2c04fa40e66097a4d6975) Various animations were marked for cancellation when launcher activity is destroyed. This this does not work with multiple activities (Launcher, fallback recents, shortcut confirmation). Also since launcher activity handles configuration changes, the activity is not destroyed often. Instead associating a target with various animations which automatically cancels the animations when that target goes away. Change-Id: I64cd095a28075561a9e20c9dcdeb9f90c18e1047
