最近一個童鞋問我，他用的是cocoslua3.17.2 建立新工程，各種問題出現，不知道怎麼辦了，希望我能協助一下，然後，我就把我線上跑的工程所用到的一些版本告訴他，沒想到，被鄙視了： 你還用AS3.2呀，太早了呀，我現在用的3.5.2，我不想用太老的呀。能幫我搞一下不？

　　就這樣，我就被鄙視了。好吧，也閒著，看一下，自己跑去下了個（你這也不是新的啊，還鄙視我，只比我用的新了那麼一捏捏而已嘛）

　　既然用新的AS了，那麼Gradle也要升級了，事實證明，gradle也不能隨便想升到幾就是幾，遇到一些問題後，最終確定一個版本

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

由於google上架要求android api版本必須在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

　　編譯時還要更改專案級build.gradle 檔案variant.mergeAssets.doLast 替換為variant.mergeAssetsProvider.get().doLast

編譯成功了，找個android手機，跑一下。

很好，不出所料，黑屏。gradle升級後，assets資料夾無法拷貝了。繼續修改專案級 build.gradle檔案

修改後的程式碼

android.applicationVariants.all { variant ->
    // delete previous files first
    delete "${buildDir}/intermediates/assets/${variant.dirName}"
    delete "${buildDir}/intermediates/merged_assets/${variant.dirName}"

　　由於我不直接用他的加密，所以加密那部分我沒太留意改的對不對。

繼續跑一下，OK 了，介面就這樣出來了，assets資料夾也打入到apk中了。全部完成。以上過成功遇到過很多問題，例如：Execution failed for task ':testdemo:externalNativeBuildDebug'. 這樣的問題。通過更改Gradle和NDK版本，基本都解決了，如果還有問題，可以在聯絡我，我們一起探討。
