Many Android apps display web content within themselves – this keeps the user from bouncing back and forth between the app and the browser, for example, when tapping on a link in Gmail. One way to do this is to use the WebView component, but Google believes that Custom Tabs are the better solution and it has now made them even better with a couple of improvements.
The first is Partial Custom Tabs. Instead of filling the whole screen, the web content can now only cover half, which improves the multitasking experience since you can still use the app (e.g. continue reading the email).
