From b2993038e541c5e4fe26a4b5b581a5c58fcea07b Mon Sep 17 00:00:00 2001 From: XuqmGroup Date: Thu, 11 Jun 2026 20:24:39 +0800 Subject: [PATCH] fix(sdk-update): make UpdateInfo.apkHash nullable to prevent NPE on missing server field Gson sets absent JSON fields to null even for Kotlin non-null types. Calling copy() on an UpdateInfo where apkHash is null triggers a runtime NPE. Declaring the field as String? and passing ?: "" at the call site is the minimal safe fix.
