That code is a few years old, so not surprising that it doesn’t work any more. Did you follow the link from the error message and understand it and follow what the solution for it is?

Problem working with an imported project in ionic 3 ( failed to load index.html )
I had a similar problem, I searched for stackoerlow answers, and on forums, but I couldn’t fix it. I then installed yarn using the command yarn install and then ran the app ionic again and ran successfully. However, I am not sure if it is due to the lack of libraries of yarn, but after I successfully ran the yarn install command, I would like to comment.

Ionic 4 native camera oddity
This is a strange one that I can’t quite understand and I think that showing the code first will be best
component.ts
this.camera.getPicture(options).then(
(imageData: string): void => {
const mp4Checker = imageData.slice(-3);
if (mp4Checker === 'mp4') {
console.log('imageData', imageData); // <-- 'path/to/storage/file.mp4'
message.video = imageData;
console.log('after assignment', message.video); // <-- 'path/to/storage/file.mp4'
this.chatService.sendVideo(message);
} else {
console.log('imageData', imageData); //<-- 'string/to/storage/file.jpg'
message.image = imageData;
console.log('after assignment', message.image); // <-- undefined
this.chatService.sendMessage(message);
}
this._uploadMedia(imageData);
},
err => {
console.log('error -->', err);
},
);
now If I move the logic to separate function it fixes the undefined problem:
this.camera.getPicture(options).then(
(imageData: string): void => {
this._uploadMedia(imageData);
},
err => {
console.log('error -->', err);
},
);
private _uploadMedia(media: string): void {
const mp4Checker = media.slice(-3);
console.log('_uploadMedia', media, mp4Checker);
if (mp4Checker === 'mp4') {
message.video = media;
console.log('look at message.video', message); // <--'path/to/storage/file.mp4'
} else {
message.image = media;
console.log('look at message.image', message); //<--'path/to/storage/file.jpg'
}
}
Why in the first example can I not assign it but after passing the reference to the helper function I am only then finally able to?

Error when subscribing to Screen Orientation changes
I am trying to use cordova’s ScreenOrientation module to get screen orientation changes. Using their example online, I’ve written this code in my 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 { ScreenOrientation } from '@ionic-native/screen-orientation/ngx';
@Component({
selector: 'app-root',
templateUrl: 'app.component.html'
})
export class AppComponent {
constructor(
private platform: Platform,
private splashScreen: SplashScreen,
private statusBar: StatusBar,
private so: ScreenOrientation,
) {
this.initializeApp();
}
initializeApp() {
this.platform.ready().then(() => {
this.statusBar.styleDefault();
this.splashScreen.hide();
console.log('orientation is', this.so.type);
this.so.onChange().subscribe(() => {
console.log('orientation changed to ', this.so.type);
});
});
}
}
When I run my app – and this is a brand new ionic project with no other changes – I see this error in the logs:
ERROR TypeError: Invalid event target

Does anyone know what this means and how to fix it? My subscriptions to the onChange events do not work, so I’m not getting the orientation changes.

Ionic 4 -¿Is there a way to observe all alerts dismisses not having to control all of them individualy?
Hi there!
I’m trying to find out if there is a way to observe or if an event is fired for all the alerts and loading dismisses in a page, where i have to setFocus() on an input where a scanner have to write.
The thing is that I have a async service function that provides me info about the product code scanned, and this one have a loading that cancel the myAlert.onDidDismiss().then(() => { this.myInput.setFocus() }).
const editAlert = await this.alertController.create({
header: 'Editando Packs de:',
message: `<p>` + itemToEdit.sscc + `</p>
<p>` + itemToEdit.layout + `</p>`,
inputs: [
{
name: 'packs',
type: 'number',
value: itemToEdit.packs,
placeholder: 'Nº de Packs'
}
],
buttons: [
{
text: 'Volver',
role: 'cancel',
cssClass: 'secondary',
handler: () => {
option.close();
this.ssccInput.setFocus();
}
},
{
text: 'Confirmar',
handler: async data => {
if (itemToEdit.packs !== data.packs) {
if (data.packs > originalProduction[0].packs) {
await this.alertWithTimeoutAndSetFocusOnSSCC(
'Error',
'El número de packs especificado <strong>supera</strong> a los disponibles',
2000
);
} else {
let newNumberOfBottles = (data.packs * itemToEdit.bottles) / itemToEdit.packs;
let newWeightOfSSCC = Math.round(((itemToEdit.weight * newNumberOfBottles) / itemToEdit.bottles) * 10) / 10;
itemToEdit.bottles = newNumberOfBottles;
let oldWeightOfSSCC = itemToEdit.weight;
this.currentLoad -= oldWeightOfSSCC;
this.currentLoad += newWeightOfSSCC;
itemToEdit.weight = newWeightOfSSCC;
itemToEdit.packs = data.packs;
this.sqlServerServices.updateEditedTransaction(
this.newWaybillSleepId,
newNumberOfBottles,
data.packs,
newWeightOfSSCC,
itemToEdit.sscc
).then(() => {
option.close();
this.ssccInput.setFocus();
});
}
}
}
}
]
});
editAlert.present();
editAlert.onDidDismiss().then(() => {
this.ssccInput.setFocus();
});
I have also tryied what im used to use async await, but nothing changes.
itemToEdit.packs = data.packs;
await this.sqlServerServices.updateEditedTransaction(
this.newWaybillSleepId,
newNumberOfBottles,
data.packs,
newWeightOfSSCC,
itemToEdit.sscc
);
option.close();
this.ssccInput.setFocus();
}
}
}
}
]
});
editAlert.present();
editAlert.onDidDismiss().then(() => {
this.ssccInput.setFocus();
});
With and without the onDidDismiss at the end.
