Use dark-mode related APIs in TWAs

Recently the following APIs for CCTs were added:
- setColorScheme
- setColorSchemeParams
- setNavigationBarColor

TWA developers should be able to use them through TrustedWebActivityBuilder
and related classes. This CL:
- Updates TrustedWebActivityBuilder
- Adds NAVIGATION_BAR_COLOR metadata for LauncherActivity
- Updates PwaWrapperSplashScreenStrategy to ensure (whenever possible) that
status and nav bar color are the same before and after browser launch.

Chrome Custom Tabs - Examples and Documentation

Chrome Custom Tabs provides a way for an application to customize and interact with a Chrome Activity on Android. This makes the web content feel like being a part of the application, while retaining the full functionality and performance of a complete web browser.


Using Custom Tabs should be easy. This repository hosts examples and in-depth documentation. The examples are importable as projects into the Android Studio.

Bugs, Issues and Discussion

We want to hear your feedback! Please create bugs and start discussions using this template. Please use the template for any issues related to the Custom Tabs APIs, their implementation in Chrome, the examples in this repository, and related functionality of the Android Support Library.

Note: we know that the GitHub issue tracker is great! However, since Custom Tabs is mostly driven by Chrome developers, and we want to keep all bugs in one place, we prefer the Chromium issue tracker at the moment.


We accept contributions to Custom Tabs examples and documentation. Please see our contributor's guide.
