Zygote的启动流程
Init进程启动后,会加载并执行init.rc文件。该.rc文件中,就包含启动Zygote进程的Action。详见“RC文件解析”章节。
根据Zygote对应的RC文件,可知Zygote进程是由/system/bin/app_process程序来创建的。
app_process大致处理流程如下,详见“app_process解析”章节。
- 创建AppRuntime
- 整理传参,并将相应参数传给Runtime或Zygote进程。
- 使用Runtime调用start方法,传入“com.android.internal.os.ZygoteInit”类和zygote传参,启动zygote。
class AppRuntime 继承自 public AndroidRuntime。调用start方法后,将执行以下步骤。详见"AndroidRuntime解析"章节。
- 搜集JVM参数,启动VM
- 注册JNI方法。
- 利用java的反射,调用com.android.internal.os.ZygoteInit类中的main方法,创建zygote进程。
Zygote代码分析
RC文件解析
Init.rc中的Zygote内容
init.rc中涉及Zygote的部分有五处。从代码中可以看出,在初始化晚期阶段late-init,会触发Zygote-start行为,而该行为会创建zygote,以及zygote_secondary两个进程。
import /system/etc/init/hw/init.${ro.zygote}.rc
import /system/etc/init/hw/init.boringssl.${ro.zygote}.rc
...
on late-init
trigger zygote-start
...
on zygote-start
wait_for_prop odsign.verification.done 1
# A/B update verifier that marks a successful boot.
exec_start update_verifier
start statsd
start netd
start zygote
start zygote_secondary
...
on userspace-reboot-resume
trigger userspace-reboot-fs-remount
trigger post-fs-data
trigger zygote-start
trigger early-boot
trigger boot
关于如何启动这两个进程,可以参照init.${ro.zygote}.rc。${ro.zygote}的值,可以通过shell指令“getprop ro.zygote”获取。以下图为例,zygote64_32代表64模式为主,32位模式为辅。
init.zygote64_32.rc
引用了init.zygote64.rc
声明了一个名字为“zygote_secondary”的service。该service将有/system/bin/app_process进程来启动。其中以“-”开头的是JVM参数,-Xzygote /system/bin。以“--”开头的是进程参数,--zygote --socket-name=zygote_secondary --enable-lazy-preload。
创建了两个socket,名字为zygote_secondary和usap_pool_secondary。
import /system/etc/init/hw/init.zygote64.rc
