How To Improving Android Boot Time
March 13th, 2012

Boot Sequence Overview
* bootloader
* kernel
* init
—- loads several daemons and services, including zygote
—- see /init.rc and init..rc* zygote
—- preloads classes
—- starts package manager* service manager
—- start services
提高Android系统启动时间， 这里只说优化Android的启动时间，不包括bootloader和Kernel的。
1. 精简init init.rc 和 init..rc
a. export ANDROID_BOOTLOGO 0 // 去掉启动画面.
b. bootanim // 去掉启动动画服务.
c. 由于设备里面没有蓝牙, wifi，所以去掉驱动了蓝牙,wifi相关的服务.
2. zygote preloads classes
在frameworks/base/core/java/com/android/internal/os/ZygoteInit.java文件里面，去掉class加载或者资源加载。 在我的s5pv210 A8板子上只提高了3秒，如果你的CPU比较差的话可能提供的更多。

3. package manager
如果我们的设备是个平板没有phone，sms功能就可以去掉不用的package包来提供Android启动时间。
修改./build/target/product/AndroidProducts.mk 文件中的PRODUCT_PACKAGES来消减多余的package包.
去掉系统默认的Launcher2， 换成我们自己的BootStart.
根据我们的设备修剪如下:
PRODUCT_PACKAGES := \
bouncycastle \
com.android.location.provider \
com.android.location.provider.xml \
core \
core-junit \
dalvikvm \
dexdeps \
dexdump \
dexlist \
dexopt \
dmtracedump \
dvz \
dx \
ext \
libdvm \
libexpat \
libicui18n \
libicuuc \
libjavacore \
libnativehelper \
libsqlite_jni \
libssl \
libz \
hprof-conv \
icu.dat \
jasmin \
jasmin.jar \
libcrypto \
libdex \
CertInstaller \
DrmProvider \
framework-res \
ApplicationsProvider \
DownloadProvider \
MediaProvider \
SettingsProvider \
UserDictionaryProvider \
DefaultContainerService \
bcm31 \
BootStart |
修改完后最好把根目录的out目录删掉，然后再整个项目编译一下。
如果编译没有错，继续进行下一步。通过消减package速度只提高了1秒左右。
5. service manager
通过修改./frameworks/base/services/java/com/android/server/SystemService.java 消减不必要的service.
根据我的设备我只保留了以下几个服务:
下面的6个服务是必须的:
*Power Manager*
*Activity Manager*
*Package Manager*
*Battery Service*
*Windows Manager*
*Connectivity Service*
下面的服务可以根据你的需求增加或者裁剪:
Entropy Service
Content Manager
System Content Providers
Lights Service
Vibrator Service
Mount Service
USB Observer
AppWidgert Service
DiskStats Service
消减服务的时候最好从服务的后面往前消减，以为各各服务之间有时是有关联的。每消减一两个服务最好编译一下，然后放到板子上跑跑，看看有没有错误信息，能不能正常进入主界面，如果不能就查看logcat日志，修复掉相关的错误信息。大部分错误信息都是空指针null, 只要加些判断就可以修复。去掉相关的服务信息提高了1s左右。
更详细的信息参考附件中的boottime.patch
6. 去掉对zip文件的检查
frameworks/base/libs/utils/ZipFileRO.cpp @@ -349,11 +349,14 @@ bool ZipFileRO::parseZipArchive(void) goto bail; } + /* FIXTHIS - skip signature check for now + * Disable By: Bian Jiang 2012.2.24 long localHdrOffset = (long) get4LE(ptr + kCDELocalOffset); if (localHdrOffset >= mDirectoryOffset) { LOGW("bad LFH offset %ld at entry %d\n", localHdrOffset, i); goto bail; } + */ |
7. 还有就是我的uboot默认等待3秒，通过修改uboot里面的CONFIG_BOOTDELAY设置为等待1秒。
具体文件在: ./include/configs/smdkc110n_mtd.h
总结:
1. 在我的s5pc110的板子上从启动时间19s优化到11s左右。
2. Kernel还有一定的优化空间，至少能再提高2秒.
