I just started a new blank angular app, then tried to build the android app :
ionic start toto blank --type=angular
ionic prepare android
ionic cordova run android
The app is ok on my computer, builds without any error, but fails to launch on device, chrome inspector says
Failed to load resource: net::ERR_FILE_NOT_FOUND
runtime.js:1 Failed to load resource: net::ERR_FILE_NOT_FOUND
styles.js:1 Failed to load resource: net::ERR_FILE_NOT_FOUND
cordova.js:1 Failed to load resource: net::ERR_FILE_NOT_FOUND
vendor.js:1 Failed to load resource: net::ERR_FILE_NOT_FOUND
main.js:1 Failed to load resource: net::ERR_FILE_NOT_FOUND
/assets/icon/favicon.png:1 Failed to load resource: net::ERR_FILE_NOT_FOUND
I inspect this :
Redmi 5 Plus
#C7B988339905
WebView in io.ionic.starter (69.0.3497.100)
Ionic App
file:///android_asset/www/index.html
inspect
What am I missing ??
nobody has encoutered this behaviour ?
How are you building the app??
just as I posted above : start a blank app, prepare android, and run android (the cli installs the android platform on the way).
The problem seems to be that the device app is just a ‘copy’ of the www folder that works ok on my computer, and the folders are not set properly ?
connect your mobile to pc via usb cable select developers on and usb debbuging also then on cli try ionic cordova run android.
I tried (changed ionic run android to ionic cordova run android, but the problem remains…I get a blank screen on the device after the splashscreen is gone.
But all seems to be fine to the cli :
C:\Users\User\PROG\toto
λ ionic cordova run android
> ng run app:ionic-cordova-build --platform=android

Are you using microsoft edge or chrome browser??
Just use the chrome browser.
I don’t want to use a browser !
My purpose is to build a ‘native’ android app to publish it on the google store…
What I can’t understant is why the “blank app” gives me a white screen… Is it a CLI bug?
I must be missing something, but what ?
I just wanted to know it it works fine on browser and problem only arises when on device.
that’s it : ok on computer, not ok on device
There must be something wrong.
Does the splash screen occurs and ends??
If nothing helps try removing the platform and re-adding it.
problem solved by removing and reinstalling ionic and cordova
