7. Android browser VS chrome android

android chrome(v18)
369
android 4.0.4r1
Qunata POC box
form+33
file +10
communication + 22
works + 10
although none video codec
is marked as supported,
but android browser DO be able
to play some html5 video.
Not sure of the video codec type
content shell
(chrome v19)
391

8. chrome 21 video/audio support
http://html5test.com/compare/browser/chrome21.html
video codec mp4v.20.8

10. Architecture diagram

11. contentView vs webView
At this stage, webview provide more
functionality than contentView
webview is much more stable than
contentView (contenView based browser is very fragile)

12. Options to build a
customize browser
webkit
(android)
webview

(option1)
customize

Android
(option2)
customize
browser
pros cons
option1
1.stable & mature API
2.android browser’s code is
open sourced and could be
leveraged
3.learning curve is low
1. less html5 support
2. wekkit is out of date and its
update cycle is limited by
Android release cycle
option2
1. better html5 support
2. multiprocess
3. stay updated (chrome V18)
1. non-stable & mature
2.chrome android is not open
source
3. learning curve is high

13. To get both benefit,
WE wish...
Webview could built upon chrome engine
Are you still working on the Android browser, or are you dropping support in favor of Chrome?
Android Browser and Chrome for Android are both derived from Chromium and already share a lot of code. We will
continue to evaluate where it makes sense to harmonize our efforts; for
instance, Google now has just one port of WebKit to maintain.

But good news is .....

Q: With Chrome on Android what happens to the original Android browser and WebView?
A: ICS->JB upgrade will not pre-install Chrome. WebView will be converted to Chromium
based code. Android and Chrome engineers are working together.
Q: Will WebView get updated?
A: WebView and Chrome browser will be the same when the OS is upgraded. Every 6
weeks Chrome will be updated but WebView will not. Just to be careful not to break anything.
Pretty Good!
What does it mean???
Webview will be chromium based

15. webkit
