-Name: Chrome Custom Tabs - Example and Usage
-Short Name: Chrome Custom Tabs Client
-URL: https://chromium.googlesource.com/external/github.com/GoogleChrome/custom-tabs-client
-Version: unknown
-License: Apache 2.0
-Security Critical: yes
-License Android Compatible: yes
-
-Description:
-This presents an example application using Chrome Custom Tabs, and a possible
-usage of both the intent and the background service APIs. It covers UI
-customization, callback setup, pre-warming and pre-fetching, and lifecycle
-management. Also inside demos there is another application that launches
-custom tabs in different modes.
-
-The example applicaton also presents how to use Browser Actions, including
-creating request intent and adding custom items.
-
-The actual code that Chromium builds from is in
-//third_party/android_sdk/androidx_browser, this subdirectory is kept around
-for the example app (the custom_tabs_client_example_apk target).
-
-TODO(peconn): Get rid of src/customtabs and depend instead on
-androidx_browser.
-
-Local Modifications: None
