After upgrading Ionic from RC1 to RC3 by following the documentation instructions, I encountered a problem where my app would not run properly on Android using ionic run android or ionic build android. Although previewing with ionic serve and building a .apk file worked fine, running the app on my device or emulator resulted in displaying the splashscreen followed by a blank WebView. Upon debugging using chrome://inspect, the console showed the error:
main.js:7 Uncaught Error: Cannot find module "./app.module.ngfactory"
I had backed up the project folder before the update when the app was functioning correctly. The code remained unchanged during the upgrade, and the files app.module.ts, main.dev.ts, and main.prod.ts appeared to be intact.
I attempted to resolve the issue by deleting the .tmp and node-modules folders and running npm install again, but unfortunately, the error persisted.
