Ionic run --prod white screeen

So I can build the app with ionic run android and if I build it with ionic run android --prod it builds without errors and launches okay.
The problem is that when I click anywhere on the app the screen turns white. This does not occur when doing a normal build

Is anyone else having this problem?

Ionic Framework: ^2.0.0-rc.3
Ionic Native: ^2.2.11
Ionic App Scripts: 0.0.47
Angular Core: 2.1.1
Angular Compiler CLI: 2.1.1
Node: 6.2.2

Not sure what to recommend here but for what it’s worth here’s what I would try:

Is your Android SDK (and any related dependencies) up to date? Update and double check.
Are there any plugins installed that, if you remove them, stop this from happening?
As a more extreme measure, have you removed the android platform and reinstalled to see if this might clear the problem?

ionic platform rm android
ionic platform add android

And you definitely get no errors during the ionic run android --prod process?

I tried everything and it still has the same problem :frowning:

I tried everythigng and it doesnt work.
Yeah my android SDKs are completely up to date (25).

Is it possible that the problem is that I am building for Android 23?

I am using ionic-app-scripts 0.0.47.

I think the problem must be with the ionic errors. the screen goes into white/transparent and if I keep on clicking after a while it turns normal again and at the next click it turns white again.

Is there a way to disable the error handling (or is that alraedy done with --prod?)?

Can you make sure everything is updated compared to the base starter?

Yes everything is updated.

I tried running with --aot and it works fine so the minification must be the problem

This problem is happening with ionic 2 RC4 too, as I stated on RC4 seems slower to load the app

I still couldn’t make the --prod run on the device without causing the blank screen…

Hello, just to say that I was able to fix this for me.

I just downgraded the typescript version to “2.0.9” (I was using 2.1) and the prod build worked as a breeze. The app loading time is even faster than with RC3.

More details here: RC4 seems slower to load the app

I changed to 2.0.0-rc.4 and I still have the same problem

yes please do not use TS2.1.

Ionic and Angular are not setup for TS2.1 yet and it will break everything

why am i getting this error

It would help to see the bit of app.module.ts that is being complained about.

That is not the app module. That is the app component. The error message is telling you exactly where the problem lies.

SO SORRY IN HURRY I UPLOADED COMPONENT FILE… BELOW IS MODULE.TS…ALSO .FEW PAGE IMPORTS NOT COPIED HERE

import { NgModule, ErrorHandler } from ‘@angular/core’;
import { RequestOptions, XHRBackend } from ‘@angular/http’;
import { IonicApp, IonicModule, IonicErrorHandler ,InfiniteScroll} from ‘ionic-angular’;
import { MyApp } from ‘./app.component’;
// import { HttpModule} from ‘@angular/http’;

import {Storage} from ‘@ionic/storage’;

import { Focuser } from ‘…/components/focuser/focuser’;

@NgModule({
declarations: [
MyApp,
],
imports: [
IonicModule.forRoot(MyApp)
],
bootstrap: [IonicApp],
entryComponents: [
MyApp,
],
providers: [{provide: ErrorHandler, useClass: IonicErrorHandler},Storage, {
provide: HttpInterceptor,
useFactory: (backend: XHRBackend, options: RequestOptions) => {
return new HttpInterceptor(backend, options);
},
deps: [XHRBackend, RequestOptions]
}]
})
export class AppModule {}

DONT KNOW WHY IT IS THROWING AN ERROR

I am using TS 2.0.9 here but the problem has not been solved.

I’m still having the same problem. I have upgraded to ionic 2.2.0 but I still do --prod builds with app-scripts 0.0.46. Everything above results 0.0.46 results in the app not passing the start screen. I tried everything including adding my src to the Ionic 2 Conference app. Same results.

Can you please post your package.json? I would like to use --prod too.

My package is the same as conference app. I just do “npm install @ionic/app-scripts@0.0.46” and then I can do a production build.
