Inconsistent behavior of "View Source" actions

[SimonMarquis]

View source action will lead to 2 different places depending on the button pressed:

• in the list view (main screen): the View source button of the overflow menu item will open a ChromeCustomTab
• in the details view (ChromeCustomTab): the View * source button in the ActionBar will open a regular ACTION_VIEW intent, and open whatever browser you have on your device

I'm working on the 2nd View Source action to load the uri into a ChromeCustomTab as well.

What's the behavior when you click "View Source" and it launches a custom tab from a custom tab? Does it overlay or does it redirect the current one?

[SimonMarquis]

It does create another Activity (CustomTab) on top of the current one (back button returns to the initial CustomTab).
Unfortunately, there is no API to redirect the user from within a CustomTab...

[JakeWharton]

Yeah I briefly went looking for one before deciding on the ACTION_VIEW intent. I'll try out the overlaying one in your PR and see how it feels.
