Q
最近遇到一個問題：多個應用打不開，閃退。
A
調查發現閃退的應用都在首屏加載了webview，而在android p上webview的渲染是在另外一個進程上進行的，進程名字類似webview:sandboxed_process0，這個進程是由webview_zygote這樣一個進程fork出來的，而webview_zygote由於缺少權限runtime崩潰，從而導致webview加載失敗，應用閃退。
S
增加相應權限
webview_zygote.te
allow webview_zygote ion_device:chr_file r_file_perms;
簡單調查了下加載webview的應用，隨android版本升級進程關係的變化
1.在android o以前
webview運行在app進程裏
2.android o
webview運行在單獨的進程裏com.android.webview:sandboxed_process(n)
webview進程是由webview_zygote進程fork出來的
而webview_zygote進程是由1號進程init進程forkc出來的
能看出不管應用進程運行時是32bit還是64bit，wevview進程的運行時應該是32bit，因爲webview_zygote是32bit的，它只能fork 32bit進程出來，生不出別的孩子
可以看到32bit,64bit運行時應用的祖宗zygote和zygote64也是init進程fork出來的

3.android p總體上和android o一樣，但是有些區別
webview運行在單獨的進程裏com.android.webview:sandboxed_process(n)
webview進程是由webview_zygote進程fork出來的
這裏稍有不同webview_zygote進程是由zygote fork出來的，當然它也只能是32bit的運行時，它兒子孫子都是

4.不但如此android o和android p編譯鏈接關係上有不同
zygote,webview_zygote編譯鏈接關係發生了變化，鏈接了不同的庫
