问题描述
最近遇到个问题，系统刷完机后，第一次开机，时间超级久，久到离谱，需要8分钟多，才能开机。生产那边先太浪费时间。先需要优化开机时间。
解决方法
1.优化开机时间，有很多种方法，但是优化第一次开机时间，先得知道第一次开机，是解包各种服务apk，加载出资源文件。
2.查找第一次开机时间久的根本原因是什么导致的。
3.怎么进行第一次开机时间优化。
1.经过排查发现，以前的固件开机时间是4-5分钟，经过排查发现，时间变长是加了gms
2.同时查看logcat信息进一步论证这个gms导致

可以很清楚的看到dex2oat 解包gms相关的apk，花费好多时间。
下面就是如何处理这个dex2oat问题
+++ b/device/rockchip/common/BoardConfig.mk
# Enable dex-preoptimization to speed up first boot sequence
ifeq ($(HOST_OS),linux)
ifeq ($(TARGET_BUILD_VARIANT),user)
ifeq ($(WITH_DEXPREOPT),)
WITH_DEXPREOPT ?= true
endif
endif
endif
要么使用user模式编译系统，要么强行WITH_DEXPREOPT ?= true
可以让系统第一次开机时间缩短到2分钟之内
另外对单个apk进行开机速度优化方法如下
apk目录下的Android.mk中添加
LOCAL_DEX_PREOPT :=true，表示优化该apk
LOCAL_DEX_PREOPT :=false，表示不优化
另外可以在系统编译dex_preopt_odex_install.mk对apk加LOCAL_DEX_PREOPT :=
+ifeq ($(LOCAL_MODULE),helloworld)
+LOCAL_DEX_PREOPT:= true//false
+endif
built_odex :=
installed_odex :=
built_installed_odex :=
这样，就可以在out目录apk的目录生成oat目录
