the android webview niels leenheer - phonegap day eu 2015
what is a webview? a system level component for
displaying html in applications
up to android 4.3, the webview was based on
webkit android 4.4 and later use a webview based on chromium
the old webkit webview has not been properly updated
in the last four years almost no changes between android 4.0 and 4.3
the webkit webview is slow and has outdated standards support
its standards support can be compared to ios 4 or 5
the chromium webview is not only much faster, it has
much better standards support at the same level or even better standards support as ios 8
the chromium webview will be updated regularly android 4.4
⟶ chromium 30 android 4.4.3 ⟶ chromium 33 android 5 ⟶ chromium 37 or higher
in a couple of years all android phones will have
the chromium webview
but today we still have to deal with the webkit
webview 5 10% 4.4 40% 4.1 - 4.3 39% 4.0 5% 2.2 - 2.3 6%
but unfortunately we are not dealing with just one webkit
webview
device manufacturers improved the default browser differentiation by having better
standards support than your competitors
differentiation is just a pretty name for fragmentation
the reality is that we now have many different webviews
that all behave slightly different not only different versions of webkit, but also different features enabled
better standards support is useless if it is only available
on a subset of devices apps still need to be build for the lowest common denominator
? webgl indexeddb websockets webaudio requestanimationframe form field types
having frequent updates is not always good! removing older
apis and features can cause legacy apps to break
some devices will never get an upgrade to android 5
chromium 30 and 33 based webviews will be around for the next couple of years
bad performance limited standards support vendor specific versions
better standards support limited control
fragmentation
how to deal with this mess
test as often as possible, on as many devices
as possible
perhaps try an open device lab? 144 labs
across 34 countries and 4002 devices available
test as often as possible, on as many devices
as possible
but there is also another solution
crosswalk
None
thank you @html5test
