  "message": "Better systrace slices for application startup.\n\nThis change adds three new timeslices :\n\n- PostFork : As soon as possible after the app forks from the\n  zygote. Can be used in conjunction with the system_server\n  \"Start proc:\" event to derive an upper bound on fork() and\n  zygote overhead.\n\n- RuntimeInit \u0026 ActivityThreadMain for ZygoteInit#runtimeInit\n  and ActivityThread#main.\n\nActivityThread#handleBindApplication and higher level functions\nare already well instrumented in systrace. handleBindApplication\nshould occur immediately after ActivityThread#main.\n\nNote that we use the Activity manager tag to make it easier to\ncorrelate these new events with surrounding events (Start proc\nand handleBindApplication) that are already using the AM tag.\n\nbug: 21632700\nChange-Id: Ibc01f1721f962c913f3c02a51763b6feb1eb6a4d\n",
