cocos2dLua3.17.2 + AS3.5.2 创建工程成功 qd

　　最近一个童鞋问我，他用的是cocoslua3.17.2 创建新工程，各种问题出现，不知道怎么办了，希望我能协助一下，然后，我就把我在线跑的工程所用到的一些版本告诉他，没想到，被鄙视了： 你还用AS3.2呀，太早了呀，我现在用的3.5.2，我不想用太老的呀。能帮我搞一下不？ 

　　就这样，我就被鄙视了。好吧，也闲着，看一下，自己跑去下了个（你这也不是新的啊，还鄙视我，只比我用的新了那么一捏捏而已嘛）

　　既然用新的AS了，那么Gradle也要升级了，事实证明，gradle也不能随便想升到几就是几，遇到一些问题后，最终确定一个版本

classpath 'com.android.tools.build:gradle:3.4.0'

distributionUrl=https\://services.gradle.org/distributions/gradle-5.4.1-all.zip

　NDK版本：  android-ndk-r19c

   由于google上架要求android api版本必须在30以上，也改了吧

# Android SDK version that will be used as the compile project
PROP_COMPILE_SDK_VERSION=30

# Android SDK version that will be used as the earliest version of android this application can run on
PROP_MIN_SDK_VERSION=16

# Android SDK version that will be used as the latest version of android this application has been tested on
PROP_TARGET_SDK_VERSION=30

　　编译时还要更改项目级build.gradle    文件  variant.mergeAssets.doLast  替换为  variant.mergeAssetsProvider.get().doLast

编译成功了，找个android手机，跑一下。

很好，不出所料，黑屏。gradle升级后，assets文件夹无法拷贝了。继续修改项目级 build.gradle文件

修改后的代码

android.applicationVariants.all { variant ->
    // delete previous files first
    delete "${buildDir}/intermediates/assets/${variant.dirName}"
    delete "${buildDir}/intermediates/merged_assets/${variant.dirName}"
    variant.mergeAssetsProvider.get().doLast {
        copy {
            from "${buildDir}/../../../../../res"
            into "${buildDir}/intermediates/assets/${variant.dirName}/res"
        }

        copy {

            into "${buildDir}/intermediates/assets/${variant.dirName}/src"
        }
        if (variant.name.compareTo('release') == 0) {
            copy {
                from "${buildDir}/../../../../../res"

　　由于我不直接用他的加密，所以加密那部分我没太留意改的对不对。

继续跑一下，OK 了，界面就这样出来了，assets文件夹也打入到apk中了。全部完成。以上过成功遇到过很多问题，例如：Execution failed for task ':testdemo:externalNativeBuildDebug'. 这样的问题。通过更改Gradle和NDK版本，基本都解决了，如果还有问题，可以在联系我，我们一起探讨。
