I am currently developing an app that help students to practice past exam questions for a matriculation exam. The catch here is to beat other apps already doing this by making questions and solutions of the app totally available offline.

My challenge now is the data is large. About #12,000 questions/solutions approximately. Where do I put this data?

Can I save it as a JSON file in the front end?.. And would it not affect performance? Apart from having to upload an heavy app file to app store.

Are there other possible solutions for making these questions/solutions available offline on ionic app. Thanks

When I enter this particular command to create a project

$ ionic start MyProject tutorial

Then, I am getting this error

I tried many things to resolve this issue, but couldn’t find a suitable solution. Please help me to resolve this. Thanks.

Hey Folks!
I’m stuck with following problem:

I recieve an dynamic HTML-Content-Snippet from an API with certain classes and ids applied.
Additionally there a dynamic and individual CSS-Stylesheet I can access through this API, too.

What i got so far:

encapsulation: ViewEncapsulation.None, is important, otherwise the classnames etc. would be changed.

What i can’t get to work is to apply the styles received from the API to the component.

The first idea was to put the style-promise-result directly here:

@Component({
  selector: 'page-dynamic',
  templateUrl: 'dynamic.html',
  encapsulation: ViewEncapsulation.None,
  style: mycssapi
})

or somehow inject it afterwards. Didn’t get it working.

The second idea was to add <style type="text/css" [innerHTML]="mycss?.styles"> or this:

<style type="text/css">{{mycss?.styles}}
  </style>

Someone an idea how to solve this?

Thank you in advance!
Markus

I’ve been looking for the source of the error for 2 hours, and I can’t find it. I have thousands of lines of code, with some processes running in background, so it’s really hard to find the exact promise that is uncaught. Because of polyfills, the stacktrace is completely useless.

Is there any way to debug this so I can find where is that promise that isn’t caught?

Thanks!

My app fetches JSON data from a backend (Google Cloud Storage) using the new Angular 5 HttpClient (from @angular/common/http). I used to add a ‘If-Modified-Since’ header to only transfer new data and get a 304 response if nothing changed, caching the data myself using @ionic/storage.

Now I noticed that, compared to older versions (Ionic 2), the caching behaviour seems to have changed. Even when I remove my caching code and do not set the header explicitly, it is still being set (verified using Chrome dev tools) and I get 304 responses! Something underneath seems to have done the caching, but I can not figure out where.

I have seen that both on Android and in Chrome (MacOS using ‘ionic serve’).

I am wondering now if Ionic / Angular uses some default built-in cache and how to configure it?

I’m still fairly new to Ionic. I’m using a provider which is registered in the app.module as a provider for authentication as I’m going to need users id and type throughout the app. In the login page I can see the account.email etc, which are bound to the interface with [(ngModel)]. The provider is also injected in the constructor as a parameter. I.e. constructor(public accountSrv: AccountService) All good.
The provider has set and get methods as well as login & logout. But cannot access any of the data instantiated by the login page, so cannot do login. Console.log logs data as unidentified.
I’m using lazy loading of pages with a blank starter.

Login page is home.ts

import { Component } from '@angular/core';
import { IonicPage, NavController, ToastController } from 'ionic-angular';
import { Account } from './../../models/account.interface';
import { AccountService } from './../../providers/account.service';

@IonicPage()
@Component({
  selector: 'page-home',
  templateUrl: 'home.html'
})
export class HomePage {

  account = {} as Account;

  constructor(private toastCtrl: ToastController,
              private navCtrl: NavController,
              public accSrv: AccountService
            ) {
    this.accSrv.setEmail(this.account.email);
    this.accSrv.setPassword(this.account.password);
  }

  doLogin() {
    // For some reason accSrv is not seeing it otherwise
    let result = this.accSrv.login();
    let resultingMessage = this.accSrv.getLoginfo();

    this.toastCtrl.create({
      message: resultingMessage,
      duration: 3000,
      position: 'top'
    }).present();

    // Login successfull so send them off to Profile page
    if(result) this.navCtrl.setRoot("ProfilePage");

  }

account.service.ts

import { Account } from './../models/account.interface';
import { Injectable } from '@angular/core';
import { AngularFireAuth } from 'angularfire2/auth';

@Injectable()
export class AccountService {

  account = {} as Account;

  constructor(private afAuth: AngularFireAuth) {
  }

  async login() {
    console.log(this.account.email);
    try {
      const result = await
        this.afAuth.auth.signInWithEmailAndPassword(this.account.email,this.account.password)

      this.account.uid = result.uid;
      this.account.logInfo = "Welcome back!"
      return true;
    } catch(e){
      this.account.logInfo = e;
      return false;
    }
  }

  setID(val) {
    this.account.uid = val;
  }

I want to display a certain image if it exists on a remote server. Otherwise, I want to show a different image. So I need a way of testing if an image exists on a remote server. I’m trying the following code, but it fails every time, even if the image is really there.

let observable = this.http.head(imageURL);
observable.subscribe(()=>{
  console.log("Success! :)");
}, (error)=>{
  console.log("Error :(");
}

The error message is something like “No ‘Access-Control-Allow-Origin’ header is present on the requested resource.” But this doesn’t make sense, because I can display the image just fine in my Ionic app if I choose to.

Any ideas?

Please fix the version conflict either by updating the version of the google-services plugin (information about the latest version is available at https://bintray.com/android/android-tools/com.google.gms.google-services/) or updating the version of com.google.android.gms to 11.0.1.

I really don’t know how to fix this?

Hello, i’m in trouble with the native ionic3 gesture.

For testing purpose i use the following function :

import {Gesture} from "ionic-angular";

touchDown() {
  console.log("Touch");
}

I have the following XHTML line:

  <button ion-button icon-end solid color="secondary" (tap)="touchDown()">Show me !</button>

But if i use the following line the console log is not triggered :

  <button ion-button icon-end solid color="secondary" (hold)="touchDown()">Show me !</button>

The amount of information is maybe cheap, don’t hesitate to ask for detail

Hello guys,

I’m sure all of you guys have observed this short gray blank screen which shows up when starting an ionic app on android.
It looks like this gray screen can’t be removed? is there a way to permanently remove this gray screen?

I finally figured out a way to completely remove splash screen and white blank loading page.
I replaced them with a custom made HTML page with css animations.

Now it’s only left to remove this gray screen to make my ionic app start like any other app built on Java or C#.

Please let me know if you guys know how to get rid of this useless gray blank screen on start up.

Thanks,

Hi everyone,

I have a search-bar present in 10 pages of my app.

<ion-content  shrink-header>

  <ion-searchbar></ion-searchbar> ...

I want to do a searchFunction, that will launch a new Page with the “SearchTerm” param => no pb for this.

But i dont want to write / copy this function in the 10 page where I need It …

What do you suggest me to use for this implementation ? Is it possible to use something like global function? Or should I encapsulate this in a component ? or something else ?

Thnaks for advice

Hi all,
i’m developing an App (Android and IOS) with pages info taken from Remote API.
I have this tree navigation:

• 1. Page 1
• 2. Page 2
• 3. Page 3
• 3.1 Page 3.1
• 3.2 Page 3.2

•   3.2.1 Page 3.2.1
  

etc…

In my nav i have only pages of first level so my navigation between pages work correctly.

Now i’m using OneSignal and in my push navigation i can set a page ID to show that page on APP.
But if i’m in “HomePage” and jump directly to, for example, page 3.2.1 how i can mantain navigation tree directive so my back button show me page 3.2 and not page “HomePage” ?

Thanks for all answers

Hi, I made a custom component and using the ionic ui components inside it. It renders but the styles are gone. Here’s my accordion custom component.

accordion.ts

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

@Component({
  selector: 'accordion',
  templateUrl: 'accordion.html'
})
export class AccordionComponent {
  @Input('title') title: string;

  text: string;

  constructor() {
  }

}

accordion.html

<ion-item>
  {{ title }}
</ion-item>
<ion-item text-wrap>
  <ng-content></ng-content>
</ion-item>

and in my page, I’m using it like this.

<ion-list>
   <ng-template ngFor [ngForOf]="getBooks()" let-book>
      <cif-accordion
        [title]="book.name">

        <button ion-button clear *ngFor="let c of book.chapters">
          {{ c }}
        </button>

      </cif-accordion>
  </ng-template>
</ion-list>

components.module.ts

import { NgModule, CUSTOM_ELEMENTS_SCHEMA } from '@angular/core';
import { AccordionComponent } from './accordion/accordion';
@NgModule({
	declarations: [AccordionComponent],
	imports: [],
	exports: [AccordionComponent],
	schemas: [CUSTOM_ELEMENTS_SCHEMA]
})
export class ComponentsModule {}

and this components module is added to the app.module.ts.

but seems the ion-item styles are not applied at all. any tips?

Hello everyone,

Is it possible to create a side menu on specific pages, is that possible?
My goal is to display a side menu when the user isn’t on the homepage, ie, when he is on the main page, and each page would be open with parameters. Moreover, according to the user who is connected to the application, I would need to display a new button in the side menu.
Thanks
