Ionic CLI v5.0.3 - External development server is not started when using ionic serve

I updated all the dependencies to the latest ones, which includes updating ionic CLI to v5.0.3.
However, now when i am using “ionic serve”, the development server is only starting on localhost:8100, and not the external url. Like it used to happen in the older version

I have used “ionic serve --address=<external_address>” command as well. This works and starts the server on the external address mentioned only, and the localhost server doesn’t work.

Couldn’t find any similar query anywhere, if there is already an existing one, please tag the same here…
Using it with capacitor.

I want to build and application where if user click on a product button a timer (2 min) will start (in any place, header and footer will be ok ) with the clicked product data (like id) and user can surf through other page during the running time and they can check the time ruining.

Popup/Bar must include 2 action yes/no and the running time and when user click on yes/no i need a callback so i can trigger some function to save the data.

During the the running time product button must be disabled.

I am using @ionic-react. It is very easy to use.

What I wonder is how to make use of input type file with a IonButton or IonFabButton? According to docs the IonInput component is for text like input types.

It is meant for text type inputs only, such as "text" , "password" , "email" , "number" , "search" , "tel" , and "url" . It supports all standard text input events including keyup, keydown, keypress, and more.

Hello,

I would like to use a Brother QL-820NWB printer on one of my projects.

I can’t find a way to implement the Brother Printer SDK on Ionic 4.

Is it possible to use an Ionic native printer or is it necessary to wait for a new Ionic native plugin dedicated to Brother?

Sincerely

I’m using intro.js to create a walkthrough on my app, and it looks great. The only issue is that it’s firing everytime the app is freshly launched. Is there a way to get it to not shoe after it’s been dismissed once. I’ve read local storage might be possible, but i can’t find anything out about it. i’m using firestore if that matters?

thanks

Ionicons hex icons codes

Hi,
Don’t know if this is the place for this question. I’m using Iconicons in a web app independently of the ionic framework. To display the icons I’m using icons hex codes. In the past I looked in the page source of ionicons to find out each icon’s hex code, but now instead of the icon it shows a square (as a font that the browser cannot read). How can I find the hex code for each icon again?

I’m working on an ionic4 app with angular and firebase.

I was building the app to android using: ionic cordova run android, it was successfully built the application. Suddenly when I’m running the same command there is an error showing:

Manifest merger failed : Attribute application@appComponentFactory value=(android.support.v4.app.CoreComponentFactory) from [com.android.support:support-compat:28.0.0] AndroidManifest.xml:22:18-91 is also present at [androidx.core:core:1.0.0] AndroidManifest.xml:22:18-86 value=(androidx.core.app.CoreComponentFactory). Suggestion: add ‘tools:replace=“android:appComponentFactory”’ to element at AndroidManifest.xml:5:5-37:19 to override.

I’ve tried to add tools:replace="android:appComponentFactory" to element at AndroidManifest.xml. And I’ve have tried also to delete the platforms/android and install it again without getting the result

Does anyone have any idea about what happening? or can anyone help me with this issue!

Android App Bundle

I have the following error when uploading to google store and it was created from Appflow

APK not optimized

Warning:

This APK generates code and resources that are not used and sent to users anyway. You can reduce the size of your app using the Android App Bundle format. If you do not optimize the app for user device configurations, it will have a larger download and installation size than what you really need. Larger apps have lower installation success rates and take up more storage space on users’ devices.

Resolution:

Use the Android App Bundle format to optimize device configurations automatically or manage them on your own with several APKs.

  • what can I do since I thought that using Appflow would solve this problem.

Implementing SSO login with ADAL and JWT on an ionic app

Hi everyone !

I’m trying to Implemente SSO login with ADAL and JWT on an ionic app.

I’m using Angular 5.2.10 and Ionic v3.

This is my auth.service.ts :

I import :

import { Injectable } from '@angular/core';
import { JwtHelperService } from '@auth0/angular-jwt';
import { Platform} from 'ionic-angular';
import { MSAdal, AuthenticationContext, AuthenticationResult } from '@ionic-native/ms-adal';
import { environment as env } from '../environments/environment';

And I’m pretty sure I’ve no problem on my environment file because I already try it on an other app.

Then I’ve a problem on my authenticate function :

@Injectable()
export class AuthService {
  constructor(
    private msAdal: MSAdal,
    private jwtHelper: JwtHelperService,
    private platform: Platform,
  ) {
    console.log("auth.service.ts constructor");
    platform.ready().then(() => {
      console.log('Activate ADAL logger GSA');
    });
  }


  public async authenticate(): Promise<boolean> {
    console.log('GSA authenticate');
    await this.platform.ready();
    console.log('Called authenticate');
    const authContext = this.msAdal.createAuthenticationContext(
      env.adAuthority,
      false
    );
    authContext.validateAuthority = false;
    // Attempt to authorize user silently
    try {
      console.log('Trying to authorize user silently');
      const silentAuthResult = await authContext.acquireTokenSilentAsync(
        env.adResourceUri,
        env.adClientId,
        undefined
      );
      console.log('Silent Auth result:', silentAuthResult);
      return true;
    } catch (err) {
      console.log(
        'Cannot authorize user silently, trying to launch login process'
      );
      try {
        const authResult = await authContext.acquireTokenAsync(
          env.adResourceUri,
          env.adClientId,
          env.adRedirectUri,
          undefined,
          undefined
        );
        console.log('Auth Result:', authResult);
        return true;
      } catch (err) {
        console.error('Cannot authorize user silently. User unauthorized or no connectivity to the authentication provider: ', err);
        return false;
      }
    }
  }

I’m getting this error :

Error: Uncaught (in promise): TypeError: Cannot set property 'validateAuthority' of undefined
TypeError: Cannot set property 'validateAuthority' of undefined
    at AuthenticationContext.set [as validateAuthority] (http://localhost:8100/build/vendor.js:126569:39)
    at AuthService.<anonymous> (http://localhost:8100/build/main.js:1407:55)```

I'm sorry if it's a dumb question, I'm a beginner, but can someone please help me with this ?

Thanks a lot !
