Is it possible to add custom request headers when using chrome custom tabs?

Question

Planning to use chrome custom tabs, however before I start I wanted to know if its possible to intercept the request and set any headers in the request similar to WebViews ?

Read through the documentation and could not find any examples or references. All I could find is the onNavigationEvent callback that tells what url browser is trying to load.

Also is it possible to stop navigation for any url if required ?

Answer 1

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

I managed to inject http headers for the first tab following this way: https://medium.com/@_rpiel/chrome-custom-tabs-and-headers-or-a-happy-open-source-story-9c3f82680eea#.l46alsivf

I don't think that it's supported for subsequent tabs for now.
