#Cocos Creator# 安卓包运行时找不到settings.js文件？
问题环境
CocosCreator工程，输出Android Studio工程，用Android Studio打开，根据提示升级相关的Gradle:
然后打包，安装到安卓手机上，运行测试，咦，怎么闪退了？
如果查看logcat日志，可以看到错误：
完整的错误信息：

这是怎么回事？
原因
首先，检查一下导出的apk包是不是正常的。
直接在Android Studio里，双击打开对应的apk，可以查看包里的内容
果然没有js文件！
有什么办法呢？
解决方法
- 重新打一个包，然后不升级Gradle，直接打包。
看看这时候的apk包是否正常：
居然是正常的，看来是升级Gradle以后的产生的问题。
- 如果升级Gradle，需要修改一下build.gradle
android.applicationVariants.all { variant ->
// delete previous files first
delete "${buildDir}/intermediates/merged_assets/${variant.dirName}"
variant.mergeAssets.doLast {
def sourceDir = "${buildDir}/../../../../.."
// 以下几行是旧的代码，在新版Gradle下有问题
// copy {
// from "${sourceDir}/res"
// into "${outputDir}/res"
// }
//
// copy {
// from "${sourceDir}/src"
// into "${outputDir}/src"
// }
//
// copy {
// from "${sourceDir}/jsb-adapter"
// into "${outputDir}/jsb-adapter"
// }
// 新的拷贝文件的方法，在新版Gradle可用
copy{
from "${sourceDir}"
include "res/**"
include "src/**"
include "jsb-adapter/**"
into outputDir
}
copy {
from "${sourceDir}/main.js"
from "${sourceDir}/project.json"
into outputDir
}
}
}
打包测试，这次从打包的临时目录查看一下，文件都在
临时文件目录：xx/app/build/intermediates/merged_assets/debug/out
