2. modify gradle Version number

use Android Studio open Cocos Creator Generated Android engineering , Point file ->Project Structure , stay Project Structure Select... In the panel Project. Enter directly on the right Gradle And the version number of the plug-in . after Android Studio I will download the corresponding version for myself .

3. modify setting.gradle To configure

File path ：

jsb-default/frameworks/runtime-src/proj.android-studio/setting.gradle

Before the change ：

include ':libcocos2dx',':game', ':instantapp'

After modification ：

include ':libcocos2dx'

Reason for modification ： Unwanted game, In less than This module is for Google Instant The use of , You can also directly shield the corresponding module .

4. modify CocosAndroid.mk

File path ：

jsb-default/frameworks/runtime-src/proj.android-studio/jni/CocosAndroid.mk

Before the change ：

LOCAL_MODULE := cocos2djs_shared

After modification ：

LOCAL_MODULE := cocos2djs

Reason for modification ：Android Studio Build It's a mistake , Can't find target “cocos2djs”

5. modify app/build.gradle

File path ：

jsb-default/frameworks/runtime-src/proj.android-studio/app/build.gradle

Before the change ：

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

    variant.mergeAssets.doLast {
        def sourceDir = "${buildDir}/../../../../.."

        copy {
            from "${sourceDir}/assets"
            into "${outputDir}/assets"
        }

        copy {
            from "${sourceDir}/src"
            into "${outputDir}/src"
        }

        copy {
            from "${sourceDir}/jsb-adapter"
            into "${outputDir}/jsb-adapter"
        }

        copy {
            from "${sourceDir}/main.js"
            from "${sourceDir}/project.json"
            into outputDir
        }
    }
}

After modification ：

android.applicationVariants.all { variant ->
    // delete previous files first
    delete "${buildDir}/intermediates/merged_assets/${variant.dirName}"
       // modify   Alarm error  API 'variant.getMergeAssets()' is obsolete and has been replaced with 'variant.getMergeAssetsProvider()'.It will be removed at the end of 2019.                          
//  variant.mergeAssets.doLast {
    variant.mergeAssetsProvider.get().doLast{
        def sourceDir = "${buildDir}/../../../../.."

        copy {
            from "${sourceDir}/assets"
            into "${outputDir}/assets"
            into outputDir.dir("assets")
        }

        copy {
            from "${sourceDir}/src"
            into "${outputDir}/src"
            into outputDir.dir("src")
        }

        copy {
            from "${sourceDir}/jsb-adapter"
            into "${outputDir}/jsb-adapter"
            into outputDir.dir("jsb-adapter")
        }

        copy {
            from "${sourceDir}/main.js"
            from "${sourceDir}/project.json"
            into outputDir
        }
    }
}

Reason for modification ： Resource replication is missing . It's basically to put into "${outputDir}/x" Change to into outputDir.dir("x")
