!!! Overview[1]
[{$pagename}] is an implementation of the [browser-view] pattern, providing a secure [Browser-view] displayed in the context of the [application].


[Chrome] is an example of a [browser] that supports [{$pagename}].

[Android] [Browser] vendors [SHOULD] implement the CustomTabsService [Custom Tabs Service] to provide this functionality to their users.

[{$pagename}] is the counterpart to [SFSafariViewController] [{$pagename}] allows developers to create a custom browser experience within the parameters of Android’s developer guidelines. They are available to all devices that can run Chrome 45 on Android 4.1+ (Jellybean June [2012]). Many goodies are included in this custom WebView, including “pre-warming” of the browser in the background “while avoiding stealing [resources] from the [application],” shared [cookies] and [permissions], and one-tap return to the app. In addition, it allows Android developers to serve content in a faster manner to users who are navigating on devices that do not have auto-updating [WebViews] instead of falling back on an older, slower [WebView].
