From 9ba7bccdfb70832df76b574b0a2d56396e48c6e7 Mon Sep 17 00:00:00 2001 From: tuanndpersonal-lab Date: Wed, 15 Apr 2026 13:20:43 +0700 Subject: [PATCH] fix(android): handle intent:// URIs for offsite payment providers Override onCheckoutLinkClicked to parse intent:// scheme URIs (used by Klarna, iDEAL) and launch them safely via ACTION_VIEW. Falls back to browser_fallback_url if no app resolves the intent. Standard http/https/mailto schemes delegate to the default handler. Security hardened: ACTION_VIEW only, CATEGORY_BROWSABLE, FLAG_ACTIVITY_NEW_TASK.
