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

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。
