[置顶] Android bootchart分析
1.首先确保编译的init被烧录到板子里面去了，源码的位置在system/core/init/
2.第一次修改后，编译了system/core/init/然后又编译了./mkkernel 生成boot.img 但是烧录进去还是不成功
3.然后 发现有一个宏没有设置 在bootchart.h里面，BOOTCHART 修改后重新编译，烧了所有的文件才可以，单烧boot.img也不行。
一般都是这几个位置影响开机时间
•Bootloader init
•Kernel init
•Zygote class preloading
•Package scanning
•Service initialization
改善开机速度几个比较好的网站：
http://elinux.org/Improving_Android_Boot_Time_Outline
http://elinux.org/Improving_Android_Boot_Time
在机器的操作如下
#echo 120 > /data/bootchart-start #120 秒是超时时间,表示 bootchart 记
录多长时间后停止记录,随时可以用命令'echo 1 > /data/bootchart-stop' 停
止
#mkdir /data/bootchart
#在 data 创建该目录,用来存放生成的
记录文件
#reboot
#重启开发板后 bootchart 会开始记录
代码修改如下，加了一下日志

４．通过busybox工具把data/bootchart／下面的文件打包后再pull出来
网址 http://www.busybox.net/downloads/binaries下载 busybox-armv7l 这个 这个是arm架构的busybox
adb push busybox-armv7l sdcard/
adb shell
#cd sdcard/
#cp busybox-armv7l /system/xbin/
#chmod 755 busybox-armv7l
#./busybox-armv7l --install ./ 要加后面的./说明是安装在当前的目录下
然后用 busybox-armv7l tar -czf bootchart.tgz *
adb pull data/bootchart/bootchart.tgz
$cd ../bootchart-0.9/
#该目录是从 http://www.bootchart.org/download.html 下载的源码解压后的
目录,直接用 apt-get install bootchart 安装的 bootchart 不能使用.
$ant
$java -jar bootchart.jar ../bootchart/bootchart.tgz
# 在 上 述 源 码 目 录 执 行 ant 命 令 编 译 后 后 生 成 bootchart.jar 文 件 ,
执行该命令后会在当前目录生成所需 bootchart.png 图片文件。

５．通过搜索关键字查找不同阶段开机的时间
ADP1 kernel boot timeweiqifa@weiqifa-Inspiron-3847:~/weiqifa/log$ grep -wrn "Freeing init memory" ./
./mobilelog/APLog_2013_0101_000118/kernel_log.boot:2608:<6>[ 8.803294].(0)Freeing init memory: 380K
apps 扫描时间
weiqifa@weiqifa-Inspiron-3847:~/weiqifa/log$ grep -wrn "Time to scan packages" ./
./mobilelog/APLog_2013_0101_000118/sys_log.boot:778:01-01 23:14:32.442762 705 705 I PackageManager: Time to scan packages: 32.978 seconds
weiqifa@weiqifa-Inspiron-3847:~/weiqifa/log$
６、测试 把system app下面的apk去掉一些
如图：
![[置顶] Android bootchart分析_第1张图片](http://img.e-com-net.com/image/info5/4a6a14ba70fb44af9ecc9ddb0e2d0268.jpg)
得到去掉apk和去掉apk后两个开机的时间比较

７、在Zygote 孵化器 这里打印扫描哪些东西的时间
日志如下：
