ionic cordova build android failed due to AOT

Question

I am new to ionic. I have created new application using the ionic framework. But when I hit command ionic cordova build android --prod --release build failed with AOT exception..

Everything working fine if I hit command ionic cordova build android --release without --prod flag.

Error Message:

First I gonna past here the missing screenshot you linked:

Then, about the solution, the error msg tells you what's the problem respectively your AudioCategoryPage is contained in two modules, therefore:

Are you using lazy loading? Remove AudioCategoryPage from app.module.ts

or

Are you not using lazy loading? Remove (delete) audio-category.module.ts

I recently had this issue, I will post my solution in case someone else needs it.

1 - Remove @IonicPage() from .ts files

2 - Delete .module.ts

I had this issue too.

And surely the solution is to delete the pagename.module.ts files and inside the page.ts file delete the @IonicPage tag.

However on nested pages DO NOT delete the .module.ts files.
