Hi, I am new in this environment, so I am following some tutorials like http://masteringionic.com/blog/2017-08-02-using-the-web-audio-api-with-ionic/

I have tried a few more and in all of them I found the same problems, the providers don’t exist, the directories created are different, also the imports root like ionic-angular don’t work and I have to use @ionic/angular but with this, I have an error of “has no exported member”.

That could be possible due to the different ionic version?

Hi everyone
I need execute a method when a form control its validated.
i tested (ionChange) with debounce and it runs without validating the control after the specified time. therefore the validation shows the control in red, but after the time it executes the method.
How could I execute the method once validated in form control?
I hope everyone understands my need.
Best regards.

Hello,

I’d like to know why when I go here in my PWA: http://ulisesceca.com the url becomes http://ulisesceca.com/home

but if i try to go directly to http://ulisesceca.com/home by typing it in the browser, it tells me it can’t find that page?

My route code is this:

import { NgModule } from '@angular/core';
import { PreloadAllModules, RouterModule, Routes } from '@angular/router';

const routes: Routes = [
  { path: '', redirectTo: '/home', pathMatch: 'full' },
  { path: 'home', loadChildren: './home/home.module#HomePageModule' },
];

@NgModule({
  imports: [
    RouterModule.forRoot(routes, { preloadingStrategy: PreloadAllModules })
  ],
  exports: [RouterModule]
})
export class AppRoutingModule { }

Thanks.

We just started getting a blank white screen after doing npm run ionic:build --prod --release, previously had no problems doing --prod --release builds.

There are no errors in the console, the only warning in the server logs is "GET /build/sw-toolbox.js.map" Error (404): "Not found" but not sure it’s that’s an issue or not.

Older posts on the forums didn’t seem to resolve the issue, we’re currently using latest @ionic/app-scripts version 3.2.4.

Strangely, doing npm run ionic:build works fine. Could the issue be related to enableProdMode on Angular?

When I redirect to the Profile page the User object is undefined. But on the second call it already exists.

Hello everybody, im having a little bit of an issue but im not sure if its my inexperience or something else hope someone can help me.
I have a login form that sends info to my backend and if everything its successful sends me to the main page of the app.
When the backend responds with error code 200 meaning all was successful, i store data to my local storage to use it along the app usage like Client name.
This is part of my login function:
Im using Angular Http module, to make the post into my backend and then i store it on my local storage.

this.GetService.getData(LOGINPREM?${urlSearchParams.toString()})
.subscribe(async data => {
this.result = JSON.stringify(data); // get data in result variable
this.allData = JSON.parse(this.result); // parse json data and pass json string
this.dataService.setjsonresult(this.result);
// alert(this.dataService.getjsonresult());
this.storage.set(‘ID’, this.allData[‘Cliente’]);
this.storage.set(‘Nombre’, this.allData[‘Nombre’]);
this.storage.set(‘Puntos’, this.allData[‘SaldoPuntos’]);
this.storage.set(‘Auth’, 1 );
this.GetService.id = this.allData[‘Cliente’];
this.GetService.cliente = this.allData[‘Nombre’];
this.GetService.puntos = parseInt(this.allData[‘SaldoPuntos’], 0 );
this.GetService.isOk = 1;
this.authService.login();
if (this.allData[‘Error’]== 200) {
const toast = await this.toastController.create({
message: "Bienvenido " + this.allData[‘Nombre’],
position: ‘top’,
duration: 2000
});
toast.present();
this.router.navigateByUrl(’/menu’);
return false;
} else {
const toast = await this.toastController.create({
message: "Codigo de Error: " + this.allData[‘Error’] + " Descripcion: " + this.allData[‘Descripcion’] ,
position: ‘top’,
duration: 2000
});
toast.present();
this.router.navigateByUrl(‘login’);
return false;
}

When i get to the main page on the ngOnInit, i use the this.storage.get to get all the variables i need like username for example.

This is my ngOnInit.ts

ngOnInit() {
this.isOk = this.newsService.isOk;
if (this.isOk) {
this.id = this.newsService.id;
this.cliente = this.newsService.cliente;
this.points = this.newsService.puntos;
} else {
this.storage.get(‘ID’).then((id) => {
this.id = id;
const urlSearchParams = new URLSearchParams();
urlSearchParams.append(‘cliente’, id);
this.newsService.getData(puntos?${urlSearchParams.toString()}).subscribe(data => {
this.data = data;
if (this.data[‘Error’] === 200) {
this.storage.set(‘Puntos’, this.data[‘SaldoPuntos’]);
this.points = parseInt(this.data[‘SaldoPuntos’], 0 );
}
});
});
this.storage.get(‘Nombre’).then((cliente) => {
this.cliente = cliente;
});
}
// this.auth();
}

I tried to store all the values in a middle service just to make sure i have the information available when getting into the main page.

My problem is when its the first time and ONLY in the first time my main page shows up, seems like the info is not ready when im trying to use it (this.cliente variable) appears empty when i display it on my html.
And when im running ionic serve on chrome i check all the information on the local storage and its there already.
How it looks like the first time i get to the main page:

screen4.png516×684 7.42 KB

How it SHOULD look like when i get to the main page, and how it looks after refreshing the page or closing and getting the app on again on device:

screen 3.png515×684 6.61 KB

So i think theres a problem with how im trying to retrieve all the data.

Should i use: this.storage.ready and inside the then retrieve all the data?
i.e

this.storage.ready().then(() => {
/** set / get some data from the local storage */
}).catch((error: Error) => {
console.error(error);
return;
})

Or i’m doing something else wrong?

Thanks for your time to read my problem, have a great day.

Well I have problem with my app. I work on some basic movie app and I can’t fetch data from API with id parameter. My code look like this.
Home.ts

goToMovie(single: any) {
    let id = single;
    console.log(id);
    this.nav.push(SinglePage, {id: id});
  }

Single.ts

export class SinglePage {

  data: Movies = <Movies>{};
  id: any;

  constructor(public navCtrl: NavController, 
                     public navParams: NavParams, 
                     private movies: MoviesServiceProvider) {}

  ionViewDidLoad() {
    this.id = this.navParams.get("id");
    this.movies.getMovie(this.id)
        .then(res => { this.id = res[0]; });
    console.log(this.id);
  }
}

Single.html

<ion-header>
  <ion-navbar>
    <ion-title>single</ion-title>
  </ion-navbar>
</ion-header>

<ion-content padding *ngIf="data">
  <p>{{data?.title}}</p>
</ion-content>

Interface.ts

export interface Movies {
    id: number,
    title: string,
    description: string,
    link: string,
    image: string,
}

Service.ts

getMovie(id: number): Promise<Movies> {
        return this.http.get('http://localhost:8000/api/movie/' + id)
            .toPromise()
            .then(response => response.json().data as Movies);
    }

My problem is that nothing is rendered in view of single.ts. In console I get expected results, values from id’s are correct. Also I don’t get any errors so if anybody knows what is problem I would be very grateful. I usually work in PHP and I didn’t work in Ionic for very long time.

Hi there,

I have data returned by API and I need to paginate the results by infinite scroll, getting all data at once is a source killer for me and also takes long time.

Logic

1. Page shows loading and gets first 10 data of API result (currently have loading but it gets all data)
2. infinite scroll (each time add 10 more data till last one)

Code

Provider

import { Injectable } from '@angular/core';
import { HttpClient, HttpHeaders } from '@angular/common/http';
import { Observable } from 'rxjs';
import { map } from 'rxjs/operators';
import { LoadingController } from '@ionic/angular';

@Injectable({
  providedIn: 'root'
})
export class CategoriesService {

  apiUrl = 'https://example.com/api/categories';

  constructor(private http: HttpClient, private loadingCtrl: LoadingController) { }

  getDetails(url) {
    const httpOptions = {
      headers: new HttpHeaders({
        'Accept': 'application/json, text/plain',
        'Content-Type': 'application/json'
      })
    };

    return this.http.get(`${this.apiUrl}/${url}`, httpOptions).pipe(
      map(category => category)
    );
  }
}

Module

import { Component, OnInit } from '@angular/core';
import { Observable } from 'rxjs';
import { CategoriesService } from './../../services/categories.service';
import { LoadingController } from '@ionic/angular';

@Component({
  selector: 'app-categories-details',
  templateUrl: './categories-details.page.html',
  styleUrls: ['./categories-details.page.scss'],
})
export class CategoriesDetailsPage implements OnInit {

  categories: Observable<any>;
  loading: any;

  constructor(
    private categoriesService: CategoriesService,
    public loadingController: LoadingController,
  ) {}

  ngOnInit() {
    this.getData();
  }

  async getData(){
    this.loading = await this.loadingController.create({
      message: 'Please wait...',
      spinner: 'crescent',
      duration: 2000
    });

    await this.loading.present();

    this.categoriesService.getCategories().subscribe((res) => {
      this.categories = res;
      this.hideLoading()
    });
  }

  private hideLoading() {
    this.loading.dismiss();
  }
}

View

<ion-content padding>
    <ion-grid>
        <ion-row>
          <ion-list *ngIf="category">
            <ion-item *ngFor="let post of category.posts">
              <ion-avatar slot="start">
                 <img [routerLink]="['/', 'posts', post.url]" [src]="post.image">
              </ion-avatar>
                <ion-label class="ion-text-wrap" [routerLink]="['/', 'posts', post.url]">{{post.title}}</ion-label>
            </ion-item>
          </ion-list>
        </ion-row>
      </ion-grid>
</ion-content>

Based on docs I added this to my view below my loop code

<ion-infinite-scroll threshold="150px" (ionInfinite)="loadMorePosts($event)">
    <ion-infinite-scroll-content
      loadingSpinner="bubbles"
      loadingText="Loading more data...">
    </ion-infinite-scroll-content>
</ion-infinite-scroll>

And this to my Module

//....
import { LoadingController, IonInfiniteScroll } from '@ionic/angular';

//...
@ViewChild(IonInfiniteScroll) infiniteScroll: IonInfiniteScroll;
//....

Now please if someone can tell me how to handle loadMorePosts($event) function for my code I’ll be appreciate it.

Good evening, thank you for helping me find a solution to this problem
ERROR Error: Uncaught (in promise): Error: Can’t resolve all parameters for LoginPage: (?, [object Object]).

login.page.ts

import { Component, OnInit } from ‘@angular/core’;

@Component({

styleUrls: [’./login.page.scss’],

export class LoginPage implements OnInit {

constructor(private authService:AuthenticationService, private router:Router) { }

ngOnInit() {

let res = this.authService.login(user.username,user.password);
if(res==true) {
this.router.navigateByUrl(‘menu’);
}else{

}

authentification.service.ts

import { Injectable } from ‘@angular/core’;

@Injectable({

Hi guys,

I am trying to save a video file. I get the blob data from recordRTC api, then I create a File:

const f = new File([blob], `video_${Date.now()}.mp4`, {
      type: 'video/mp4'
});

But I can not save it since it asks for a string. I have tried this two functions to convert it to base64 first:

 getBase64(file, callback) {
    const reader = new FileReader();
    reader.onload = () => {
        callback(reader.result);
    };
    reader.readAsDataURL(file);
  }

  getBase64New(file) {
    return new Promise((resolve, reject) => {
      const reader = new FileReader();
      reader.readAsDataURL(file);
      reader.onload = () => resolve(reader.result);
      reader.onerror = error => reject(error);
    });
  }

But no luck. Any idea?

Thanks a lot.

Hi,

I have trouble to deposit data to database in firebase in Ionic 4, I tried to
create a module storage with a provider StoreToFirebaseService to save data to firebase.

I did the following:

npm install firebase angularfire2

2. add config to app/environments/environment.ts

export const environment = {
production: false,
firebase: {
apiKey: ‘’,
authDomain: ‘’,
databaseURL: ‘’,
projectId: ‘’,
storageBucket: ‘’,
messagingSenderId: ‘’,
appId: “”
}
};

3. storage.module.ts

import { AngularFireModule } from ‘angularfire2’;
import { environment } from ‘…/…/environments/environment’;
import { AngularFirestoreModule } from ‘angularfire2/firestore’;

@NgModule({
declarations: ,
imports: [
CommonModule,
AngularFireModule.initializeApp(environment.firebaseConfig),
AngularFirestoreModule
],
providers: [ StoreToFirebaseService ]
})
export class StorageModule { }

4. store-to-firebase.service.ts

…
import { AngularFirestore } from ‘angularfire2/firestore’;
…

export class StoreToFirebaseService {

constructor(
public afs: AngularFirestore
) {
}

addSurvey(){
  console.log("Inside addSurvey!");
  return new Promise<any>((resolve, reject) => {
    this.afs.collection('/result').add({
      ID: "Q2",
      Result1: false,
      Result2: false
    })
    .then(
      (res) => {
        resolve(res)
      },
      err => reject(err)
    )
  })
}    

}

5. In the component, I imported the service

import { StoreToFirebaseService } from ‘…/…/storage/store-to-firebase.service’;

export class InitiatedDrinkComponent implements OnInit {

constructor(
private storeToFirebaseService: StoreToFirebaseService
) { }

storeData(){
console.log(“Inside storeData”);
this.storeToFirebaseService.addSurvey();
}

}

6. Fore firebase database, I start in test mode with an empty database.

But “result” is not created with the fields ID, Result1 and Result2, any suggestion? Thanks!

cordova-music-controls isn’t working and doesn’t have a lot of active development. Is there any alternative plugin for getting music controls when the app is running in background??

I’ve tried multiple plugins and nothing seems to work.

Hello, im developing a position(GPS) based report online and offline app, i have add pictures and obtain latitude and longitude, but if it is offline, i should store that data inside an SQLITE table.

The problem is that when im asking the app to verify for the network state with the next code, it says the network is 4G, the PROBLEM is that even when the service is turn it off by the communication company, meaning that i CANT EVEN USE GOOGLE, the connection type also says im using 4G, I NEED THAT IT SAYS THAT IT IS OFFLINE

function checkConnection() {
var networkState = navigator.connection.type;

  var states = {};
  states[Connection.UNKNOWN]  = 'Unknown connection';
  states[Connection.ETHERNET] = 'Ethernet connection';
  states[Connection.WIFI]     = 'WiFi connection';
  states[Connection.CELL_2G]  = 'Cell 2G connection';
  states[Connection.CELL_3G]  = 'Cell 3G connection';
  states[Connection.CELL_4G]  = 'Cell 4G connection';
  states[Connection.CELL]     = 'Cell generic connection';
  states[Connection.NONE]     = 'No network connection';

  alert('Connection type: ' + states[networkState]);

}

checkConnection();

import { NavController } from '@ionic/angular';
import * as firebase from 'firebase';
@Component({
  selector: 'app-login',
  templateUrl: './login.page.html',
  styleUrls: ['./login.page.scss'],
})
export class LoginPage implements OnInit {
  verificationId: any;
  code = '';
  phone: number;

  constructor(public navCtrl: NavController) { }

   ngOnInit() {}

  send() {
    const tell = '+91' + this.phone;
    (<any> window).FirebasePlugin.verifyPhoneNumber(tell, 60, (credential) => {
      console.log(credential);
      this.verificationId = credential.verificationId;
    }, (error) => {
      console.error(error);
      alert(error);
     });
  }

  verify() {
    const signInCredential = firebase.auth.PhoneAuthProvider.credential(this.verificationId, this.code);
    firebase.auth().signInWithCredential(signInCredential).then((info) => {
      console.log(info);
      // this.navCtrl.navigateRoot('/home'); 
    }, (error) => {
      console.log(error);
    });
    }
}

While surfing i got this solution ,Here they are performing verification of the CAPTCHA also, I don’t want this functionality. I just want OTP verification.

So I’ve searched for it and I found this and this and currently i have my system settings like:

Yet I’m getting same error as before.

Any idea how to fix this issue?
