Android- EXTRA_HEADERS is not reflecting in updated Chrome version greater than 83

Question

Earlier the EXTRA_HEADERS passed to the customTabsIntent.intent.putExtra(Browser.EXTRA_HEADERS, headers), was working fine. After Chrome updated to 83, it stopped passing the header data.

   public static void startCustomTab(String url, Context context) {
    CustomTabsIntent.Builder builder = new CustomTabsIntent.Builder();
    CustomTabsIntent customTabsIntent = builder.build();
    builder.setShowTitle(true);
    Bundle headers = new Bundle();
    headers.putString(context.getString(R.string.type), "android");
    headers.putString(context.getString(R.string.source), "app");
    customTabsIntent.intent.putExtra(Browser.EXTRA_HEADERS, headers);
    customTabsIntent.intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    customTabsIntent.launchUrl(context, Uri.parse(url));
}

Answer 1

Adding custom headers was removed due to being a vulnerability. CORS safe-listed request headers are still supported. You can read more about this change here: http://crbug.com/873178
