Promises are so strange for me.

Look at this code

playAudio(index){

   storageRef.getDownloadURL().then(onResolve, onReject);

   function onResolve() {
     storageRef.getDownloadURL().then(function(url) {
       console.log(url);
       sMedia.playAudio(url);
     })
     console.log("File found!")
   }

   function onReject() {
     this.presentAlert();  /* <---- This is the problem */
     console.log("File don't exist.")
   }

presentAlert() {
   let alert = this.alertCtrl.create({
     title: 'Ops!',
     subTitle: "No file for this search",
     buttons: ['OK']
   });
   alert.present();
}

This code seems to work. If the file exist on Firebase then the function onResolve() works fine. Instead if the file don’t exist then the console log is displayed but the function is not execute.

This because the function presentAlert() is invisible inside function onReject(). Why? How can i solve this problem?

Thank you!

Hi Everyone,

I want to create a full page loading screen for ionic3 app to improve the user experience.

Currently I am curious if there is a built-in function that can be called once everything on the page is loaded, including the images so that I can switch the loading screen to the loaded screen once everything finish loading.

Hi everyone,

I am facing an issue with loading images onto my ionic page. In detail, my page has many images to be loaded and they are of different sizes. Because loading takes a while, some images appear before the others and this creates a very bad user experience.

For example the page should be like this:

Then in reality image3 loads first and for a while it becomes:

---

Then Image 1 loads:

Then finally image 2 loads

So I think there are 3 solutions but I don’t know how to do it in ionic:

1. A full screen loading screen until everything loads finish
2. A dedicated pre-loading screen for each image to load so their sequence do not get mixed up
3. A skeleton screen like facebook’s that also waits till everything finish loading before disappearing.

However does anyone knows how to create a loading screen and only transition after all content are loaded? Not only the html loads but the images loads too.

Thank you hope this is clear.

Hello,
I’m just starting with Ionic-3 and its structure.
I’m writing a simple app starting from tab template and I’ve added two simple components to understand them.
Refreshing the page in a browser I receive the following error:

Error: Unexpected module ‘ComponentsModule’ declared by the module ‘AppModule’. Please add a @Pipe/@Directive/@Component annotation.

import { NgModule, ErrorHandler } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';

import { MyApp } from './app.component';

import { AboutPage } from '../pages/about/about';
import { ContactPage } from '../pages/contact/contact';
import { HomePage } from '../pages/home/home';
import { TabsPage } from '../pages/tabs/tabs';
import { QrCodePage } from '../pages/qrcode/qrcode';

import { StatusBar } from '@ionic-native/status-bar';
import { SplashScreen } from '@ionic-native/splash-screen';
import { QRScanner } from '@ionic-native/qr-scanner';

import { ComponentsModule } from '../components/components.module';

@NgModule({
  declarations: [
    MyApp,
    AboutPage,
    ContactPage,
    HomePage,
    TabsPage,
    QrCodePage,
    ComponentsModule
  ],
  imports: [
    BrowserModule,
    IonicModule.forRoot(MyApp),
  ],
  bootstrap: [IonicApp],
  entryComponents: [

  ],
  providers: [
    StatusBar,
    SplashScreen,
    QRScanner,
    {provide: ErrorHandler, useClass: IonicErrorHandler}
  ]
})
export class AppModule {}

The components.module.ts was auto generated by the ionic command and is:

import { NgModule } from '@angular/core';
import { JokeComponent } from './joke/joke';
import { JokeListComponent } from './joke-list/joke-list';
@NgModule({
	declarations: [JokeComponent,
    JokeListComponent],
	imports: [],
	exports: [JokeComponent,
    JokeListComponent]
})
export class ComponentsModule {}

Both the components are annotated by @Component.

Which is the problem?

Good day

I am new to the Ionic platform, and a trying to implement an animated splash screen. From my research it appears that it needs to be faked by showing a blank splash screen, then loading the animation once the app has started.

I found a wonderful tutorial on how to best do so in Ionic 3.0 here, but there are some differences between 3.0 and 4.0 making it difficult to implement this approach.

I have discussed it with a colleague of mine who is more experienced with the platform, and he suggests that we, similarly to the above mentioned tutorial, simply use a blank splash image, then play the animation first thing when the app loads, after which we show the “first page” so to speak.

Would this be suitable, or are we missing something important that might make the app appear slow?

Any advice would be greatly appreciated

Dear Master,

i want to passing data API from page one to page two.
let say i have data from API like this:

categories:[
{
id: 001
main_id: 001
depth: 0
name: Man
},{
id:002
main_id: 002
depth: 0
name: women
{
id: 003
main_id:001
depth: 1
name: business_man
},{
id:004
main_id: 002
depth: 1
name: business_girl
}
]

and when i serve the ionic the output of **first page** will printed like this:

1. man  1
2. women  2

HTML code of **PageOne** like this:

<ion-item class=“tab2-selectCategory” *ngFor=“let takeData of category; let i=index” >

  <button (tap)=depth1()>{{i+1}} {{takeData.name}}  {{takeData.id}}</button> 
</ion-item>

and PageOne.ts File like this:

let filter = ;

        filter.push({
            field: 'depth',
            operator: '=',
            value: '0',
            mode: 'and'
        });

let param = {

api_token: '086090c7-2c12-4f00-9ac1-'',
select: 'id,depth,name',
filter: JSON.stringify(filter)

};

let apiUrl = ‘http://127.0.0.1/dev_inventory_1/public/api/v1/categories’;

this.httpClient.post(apiUrl, null, {params: param}).subscribe(
getData => {
this.kategori = getData[‘categories’];
loader.dismiss();
depth(){
this.navCtrl.push(PageTwo)
}

the question is how to send the id from page one to page two?
so, when i click 1.Man , the id (by tapped) passing to second page. in second page the sistem will print:
Business Man

and when click 2. Women (in page one) the page two will print:
Business Girl

thanks for your helping.

[ERROR] An error occurred while running subprocess ionic-app-scripts.

php:

<?php


$host = "192.168.xxx.xxx";
$user = "root";
$passwort = "pass";
$dbName = "connectedcar";


$db_connection = mysqli_connect($host,$user,$passwort,$dbName);

if ($db_connection) {

    $utfQuery = "SET NAMES 'utf8'";
    mysqli_query($db_connection, $utfQuery);

    $query = "SELECT wert FROM ultraschall WHERE id = 1";
    
    $result = mysqli_query($db_connection, $query);

    $ult1 = $result->fetch_all();

    echo json_encode($ult1);

    
    
}

else {
    die("Die Verbindung zur Datenbank ist fehlgeschlagen");
}
?>

and the provider:

import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';



@Injectable()
export class GlobalProvider {

dif1:number;

constructor(public http: HttpClient){}

insertIn() {
    this.http.get("http://192.168.xxx.xxx/test/getUltra1.php").subscribe( data => {
        this.dif1 = JSON.parse(data["body"]);
    })
}

}

when i use the insertIn() function i get this error. if i don´t use it, it works.
