CocosCreator3.5.0 16kb适配分享

Creator 3.x
#1

潜水多年，正好改到了分享一下（chatgpt强力援助）
androidstudioV:2025.1.4
agpV:8.10.0
graldeV:9.0.0
ndkV:28.2.13676358

项目路径\native\engine\android\CMakeLists.txt：
原：cmake_minimum_required(VERSION 3.8)
改：cmake_minimum_required(VERSION 3.22)
在 cc_android_before_target 之后， cc_android_after_target 之前添加
target_link_options(${CC_LIB_NAME} PRIVATE “-Wl,-z,max-page-size=16384”)

项目路径\native\engine\android\app\build.gradle：
externalNativeBuild{
cmake{
cppFlags “-frtti -fexceptions -fsigned-char -std=c++17”
}
}

在 externalNativeBuild 下面添加
buildFeatures{
buildConfig = true
}

到这里打包应该是正常的，下面改引擎
