How do you add custom HTTP headers to Chrome Custom Tabs?

Question

With standard Android WebViews, you use WebView.loadUrl(String url, Map<String, String> additionalHttpHeaders). How do you add your additional headers with Chrome Custom Tabs?

Answer 1

I'm not sure if you can send headers or anything related to the http request besides the url. I hope future versions will allow sending headers in Bundle when you establish CustomTabSession or so.

Entire http call is managed in CustomTabActivity.

Edit:

As of recent updates of the library, you can now add Bundle and pass it to the CustomTabsIntent intent as extra with key Browser.EXTRA_HEADERS

Bundle headers = new Bundle();
headers.putString("header1", "value1");
headers.putString("header2", "value2");
customTabsIntent.intent.putExtra(Browser.EXTRA_HEADERS, headers);

Answer 2

The above mentions solutions won't work for new version of ChromeTab.Please follow this link fix for work around.You can also study the medium post by Romain Piel which implicitly states the usage and the work around for adding headers.
