android app内置webview，随android版本升级进程关系的变化

Q

最近遇到一个问题：多个应用打不开，闪退。

A

调查发现闪退的应用都在首屏加载了webview，而在android p上webview的渲染是在另外一个进程上进行的，进程名字类似webview:sandboxed_process0，这个进程是由webview_zygote这样一个进程fork出来的，而webview_zygote由于缺少权限runtime崩溃，从而导致webview加载失败，应用闪退。

S

增加相应权限
webview_zygote.te
allow webview_zygote ion_device:chr_file r_file_perms;

简单调查了下加载webview的应用，随android版本升级进程关系的变化

1.在android o以前

webview运行在app进程里

2.android o

webview运行在单独的进程里com.android.webview:sandboxed_process(n)
webview进程是由webview_zygote进程fork出来的
而webview_zygote进程是由1号进程init进程forkc出来的
能看出不管应用进程运行时是32bit还是64bit，wevview进程的运行时应该是32bit，因为webview_zygote是32bit的，它只能fork 32bit进程出来，生不出别的孩子
可以看到32bit,64bit运行时应用的祖宗zygote和zygote64也是init进程fork出来的

u0_i185 29184 1943 1474636 18096 0 0 S com.android.webview:sandboxe

3.android p总体上和android o一样，但是有些区别

webview运行在单独的进程里com.android.webview:sandboxed_process(n)
webview进程是由webview_zygote进程fork出来的
这里稍有不同webview_zygote进程是由zygote fork出来的，当然它也只能是32bit的运行时，它儿子孙子都是
USER PID PPID VSZ RSS WCHAN ADDR S NAME
root 1 0 60588 1576 0 0 S init

root 573 1 1628984 120228 poll_schedule_timeout 0 S zygote
webview_zygote 2003 573 1631044 58384 poll_schedule_timeout 0 S webview_zygote
u0_i1 6247 2003 1181360 18528 ep_poll 0 S com.android.webview:sandboxed_process0

4.不但如此android o和android p编译链接关系上有不同

zygote,webview_zygote编译链接关系发生了变化，链接了不同的库
