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 "${outputDir}/jsb-adapter" // } // copy { // from "${sourceDir}/main.js" // from "${sourceDir}/project.json" // into outputDir // } // 新的拷贝文件的方法,在新版Gradle可用 copy{ from "${sourceDir}" include "res/**" include "src/**" include "jsb-adapter/**" include "main.js" include "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
