我使用此命令:

ionic cordova构建android --prod --release

ionic cordova build android --prod --release

发生了什么事?

推荐答案

这是ionic 4的一个重大缺陷.我建议遵循以下构建说明:

This is a massive flaw in ionic 4. I recommend following these build instructions:

测试APK:

从项目中删除"www"文件夹

Delete 'www' folder from project

ionic cordova build android --minifycss --optimizejs --minifyjs

生产APK:

从项目中删除"www"文件夹

Delete 'www' folder from project

ionic cordova build android --minifycss --optimizejs --minifyjs --release --prod

理论上--minifycss --optimizejs --minifyjs全部由--prod应用，但您永远都不知道Ionic

In theory --minifycss --optimizejs --minifyjs are all applied by --prod but you never know with Ionic
