Hi,
on an Ioni4 app, when I open the camera to read the QrCode the app crashes.
It crashes after the request of the permission of using the camera of the phone.
I’m using
phonegap-plugin-barcodescanner 8.0.1 "BarcodeScanner" and @ionic-native/barcode-scanner ^5.0.0 .

I’ve tried on Android6 and Android9 the result is the same.

Probably I didn’t install the right version of some component, but how can I know which of them is wrong?

This is the configuration of the system:

What could be the problem?
I have no error either running it in debug “ionic cordova run android”.

Same question like here: https://stackoverflow.com/questions/55967516/nsurlconnection-error-1100-while-running-ionic-app-on-ios

I have build an app with ionic 4 and cordova. On android the app runs like a charm but on iOS I just get some strange problems… like others do (https://stackoverflow.com/questions/48870411/ionic-ios-app-nsurlconnection-error-1100, https://stackoverflow.com/questions/55931112/ionic-4-app-shows-white-screen-on-ios-with-error-code-1100).
The app ionic build runs fine without any errors and just a few warnings of unused imports. Also the xcode build is fast and successfull. But when the app is running on a real device or simulator, I just get a blank white screen. In the console I get this with addional debugging:

I found like mentioned some similar issues and also added the environment variable (CFNETWORK_DIAGNOSTICS = 1) for advanced network logging to get more infos in the console (whole file: https://pastebin.com/Ew2rXPAd) or some snippets here:

It seems like the app can’t load its own files… since the error -1100 means NSURLErrorFileDoesNotExist

Hi,

I’d like to know if there is a way or workaround to track a ‘completed’ event for the ionRefresher within the html template only.

Obviously we call the refresherEvent.target.complete() in the ‘controller’ by hand so I can put the ‘extra’ lines there, but I want to handle some simple UI logic just in the html template itself.

What I had in mind:

<ion-refresher (ionRefresh)="refreshing = true; doRefreshStuff($event);" (ionCompleted)='refreshing = false;' slot="fixed" >
  <ion-refresher-content></ion-refresher-content>
</ion-refresher>

<ion-skeleton-text animated *ngIf='refreshing'></ion-skeleton-text>

So the idea is to control the 'refreshing' value only from within the template and (in this case) to show/hide the ion-skeleton-text component.

Looking forward to hear some ideas about this…
P.s. example is Ionic ‘4’ but this applies to all versions

Hi all,

i have a app with a login-page.

If the user starts the app for the first time the login-page will be shown and the user has to login. If that was succesfull the app redirects the user to the menu-page (and this loads the tabs and so on).

Now, if the user closes the app or sends it to the background and reopens the app, the login-page is shown for a short period of time (less than 1 second) and it redirects again to the menu-page.

How can i prevent the login-page to be shown when the user is already logged in and the user is reopening the app? With ionic 3 that was no problem for me (using setRoot) but now with ionic 4 i face this problem (maybe because of the routes…?)

Here are some code snippets from my code:

app-routing.module.ts

const routes: Routes = [
  { path: '', redirectTo: 'login', pathMatch: 'full' },
  { path: 'login', loadChildren: './pages/login/loginPage.module#LoginPageModule' },
  { path: 'menu', canActivate: [AuthGuard], loadChildren: './pages/menu/menu.module#MenuPageModule' },
]

app.component.ts

 this.splashScreen.hide();
            this.authenticationService.authenticationState.subscribe(state => {
                if (state) {
                    this.navController.navigateRoot(['menu/tabs/dashboard']);
                } else {
                    this.navController.navigateRoot('login')
                }
            });

In my AuthGuard i simply check if the user is logged in and return true or false. I followed this tutorial: https://devdactic.com/ionic-4-login-angular/

What do i have to do?

Hi,

I am using ionic 4, and working with modals.

The problem I have is that my modals only work, in a given page, when I import them directly in the app.module.ts, but If load them in the page’s module (in order for the modals to be loaded when that module loads), then they don’t work.

This is my modal module:

@NgModule({
	declarations: [ScanListModal],
	imports: [
		CommonModule,
		FormsModule,
		IonicModule,
		BasePageModule
	],
	entryComponents: [ScanListModal]
})
export class ScanListModalModule {
}

And this is my page’s module, when loading the modal:

const routes: Routes = [
	{
		path: '',
		component: ScanSessionPage
	}
];

@NgModule({
	imports: [
		CommonModule,
		FormsModule,
		IonicModule,
		RouterModule.forChild(routes),
		BasePageModule,
		CommonComponentsModule,
                ScanListModalModule
	],
	declarations: [ScanSessionPage],
	providers: [],
	entryComponents: [],
	exports: []
})
export class ScanSessionPageModule {
}

And that does not work. But if I remove the import there, and import the modal’s module in app.module.ts, it works.

But my guts tells me that I should just load that modal in the modules that actually use them, not globally for the app, right?

Any help would be appreciated.

Thanks!

Hi all, I’m a newbie here on the ionic/android developing world, so first, let me thanks anyone will answer me!

I’ve built a very simple Ionic 4 app that play some audio stream. It works nice, however the audio stops when the app goes in background, after more or less 3 minutes. This is due the Android Battery Optimization built in the system. (if you manually exlude the app from those optimizations, the app works forever…)

So my question: is there a way to exclude my app from those battery optimizations during the install process and/or at the first launch of my app?

I’ve been playing with the REQUEST_IGNORE_BATTERY_OPTIMIZATIONS attribute into the AndroidManifest.xml but so far, didn’t get it work.

Here the versioning of my environment:

I’d like to build an app using Ionic 4 that simplistically works the following way:

• On-boarding page is shown with some images/text
• After user clicked ‘start’ button, some flag onboarded=true is written into local-storage
• User redirected to the main app view which is a ion-split-pane containing side-menu layout
• Next time when user launches app, I check if he/she already viewed on-boarding screen (by checking presence of onboarded var) and if it is - I immediately redirect the user to the main app having side-menu layout as I mentioned, omitting on-boarding screen

I started the project using ionic cli, based on side-menu template and modified it the following way to fulfill logic described above:

app.component.ts

import { Component } from '@angular/core';
import { Platform } from '@ionic/angular';
import { SplashScreen } from '@ionic-native/splash-screen/ngx';
import { StatusBar } from '@ionic-native/status-bar/ngx';
import { Storage } from '@ionic/storage';
import { Router } from '@angular/router';

@Component({
  selector: 'app-root',
  template: '<router-outlet></router-outlet>',
})
export class AppComponent {

  constructor(
    private platform: Platform,
    private splashScreen: SplashScreen,
    private statusBar: StatusBar,
    private storage: Storage,
    private router: Router
  ) {
    this.initializeApp();
  }

  async initializeApp() {

    await this.platform.ready();

    this.statusBar.styleDefault();

    this.splashScreen.hide();

    const onboarded = await this.storage.get('onboarded');

    if (onboarded) {

      this.router.navigate(['main-app']);

    } else {

      this.router.navigate(['onboarding']);
    }
  }
}

import { Component } from '@angular/core';

@Component({
  selector: 'app-main-app',

export class MainAppPage {

  public appPages = [
    {
      title: 'Home',
      url: '/home',
      icon: 'home'
    },
    {
      title: 'List',
      url: '/list',
      icon: 'list'
    }
  ];

  constructor() { }

}

List and Home pages are just empty pages and their content is not important for this example
Problem is that main-app containing side menu and content is not working properly. I know that there is a problem in <ion-router-outlet main></ion-router-outlet>'s usage but couldn’t find the right solution.
Does anyone have ideas how to fix it?

Thanks!
Andrew.

From what I can imagine there’s 3 ways to know what is the latest versions:
1 - Check what is the latest version from a JSON file in the server
2 - Check what is the latest version from a table in the db
3 - Check what is the latest version from the app store itself

I know how to do 1 and 2 but I’ve searched on google and I don’t find how to do number 3 which would be the ideal one, do you guys know how do to it? If 3 ends up not working, which one do you guys recommend using, 1 or 2 ?

Also I have one more doubt:
In config.xml I can find version=“0.0.1” and that’s where I would expect to modify it too, but what’s up with this “version”: “0.0.1” in package.json ? do I have to change that one too or does changing one change the other?

I ran the following command:

ionic build --prod --release --platform=android

The build succeeded, however I am unable to locate the APK file generated. Any ideas as to where this might be?

Hi!
I have problem with file transfer plugin, I can not download files (although in some tests I get a url through entry.toURL (), but on going the folder has nothing).

I wonder if have other ways to download files on Ionic 4 (Android and iOS) other than file-transfer?
I use Firebase Storage as a file / image server and I have the download url, also provided by Firebase Storage.

Thank you!

I am trying to open a new window on a button click with the below code, but the button event is not triggered on iOS Safari. I can’t use inAppBrowser for this because it needs to work as a web app.

buttonClick() {
const newWindow = window.open(this.website.url, '_system');
newWindow.focus();
}

I appreciate any feedback
