I’m trying to generate the icons needed to send the app to revision… But it’s necessary send with some specific dimensions.

How can I achieve this quickly? Because in the Mac I don’t have installed photoshop and I cannot use the screenshots from the emulator because are too small.

Thanks

Hi,

So this was working fine and after and Ionic 3 version update, I’m getting the below error,

ERROR Error: Uncaught (in promise): TypeError: Cannot read property 'OneSignal' of undefined

I have the below in my index.html,

 <!-- un-comment this code to enable web push -->
  <script src="https://cdn.onesignal.com/sdks/OneSignalSDK.js" async='async'></script>
  <script>
    var OneSignal = window.OneSignal || [];

and then I init it as below to try to obtain my playerId.

initWebPush()

  this.OneSignal = window["OneSignal"];
  this.oneSignalId = "";


  this.OneSignal.push(["init", {

            that.oneSignalId = userId;
          });
        });
      }
    });
  });

  this.OneSignal.on('notificationDisplay', function (event) {
    that.notificationDisplayed(event);
  });
}

The modal dialog still appears allowing me to enable notifications but it fails to get the User Id.

Any help appreciated.

Thanks.

Hello,

I have read many threads about my issue but none of them seems to have the working solution.

I have an ion-footer element and want to hide this when I open the keyboard. Right now the footer will stick on top off the keyboard, blocking a part of the view. Does anyone have a working solution for Ionic 3?

Thanks in advance

Dear friends, greetings to all!!

I’m Pedro, a new kind of programmer…

I’m trying to sync asyncronous callings to do a google authentication, but it’s not following the supposed order (and I’m getting crazy). It’s getting doing login, but not in the correct order…

Can anybody help me, pleeeeasee??

This is the main code:

this.authProvider.getGoogleLoginCredential()
  .then(() => {
    console.log("1: entering firebaseAuthentication");
    this.authProvider.firebaseAuthentication();
    console.log("3: exiting firebaseAuthentication");
  }).then(() => {
    console.log("entering getUser().uid");
    this.authProvider.getUser().uid;
  }).then(() => {

Here authProvider where methods are called:

public firebaseAuthentication(): Promise {
return this.afAuth.auth.signInWithCredential(this.credential)
.then((success) => {
console.log('2: Firebase Authentication success: ’ + JSON.stringify(success));
})
}

getGoogleLoginCredential(): Promise {
return this.googlePlus.login({
webClientId:
‘xyxy.apps.googleusercontent.com’
, offline: false
}).then(res => {
this.googleLoginData = (res);
console.log(this.googleLoginData);
this.credential = firebase.auth.GoogleAuthProvider.credential(
res.idToken
);
console.log(this.credential);
}
).catch(err => console.error(err));
}

And here is the result:
1: entering firebaseAuthentication
modal-login.ts:63
3: exiting firebaseAuthentication
modal-login.ts:65
entering getUser().uid

TypeError: Cannot read property ‘uid’ of null

I have an issue with the slides

Originally my mark up was

<div id="slide-container">
<ion-slides autoplay="3000" loop="true" effect="fade">
<ion-slide *ngFor="let  g of sponsorGraphicsArr">
    <div *ngIf="g['iphone5GraphicURL'] && !platform.is('tablet')" class="home-bg" [style.backgroundImage]="'url(' + serverName + g['iphone5GraphicURL'] + ')' | safe: 'style'" id="background-image"></div>
    <div *ngIf="g['ipadProGraphicURL'] && platform.is('tablet')" class="home-bg" [style.backgroundImage]="'url(' + serverName + g['ipadProGraphicURL'] + ')' | safe: 'style'" id="background-image"></div>
</ion-slide>
</ion-slides>
</div>

The last slide would play twice in the loop.

(Also the second slide would pass very quickly).

Then I tried disabling the input parameters and doing it in the controller.

ngAfterViewInit(){
            setTimeout(() => {
            this.sliderIni();
            },1000)

    }

    sliderIni(){
       this.slides.effect='fade';
       this.loopSlider();
    }

    public async loopSlider() {
    let i = 0;
    while (i <= this.sponsorGraphicsArr.length) {
       await new Promise<void>(resolve => {
           setTimeout(resolve, this.sliderDelay);
       });
       this.changeSlide();
    }
    console.log('done');
}

    public changeSlide(): void {

          if(this.slides.isEnd()) {
                this.slides.slideTo(0, 300)
          }else{
               this.slides.slideNext(300);
          }
    }

This works better than the slider out of the box in that it doesn’t play the last slide twice and all the slides are evenly timed. However there is no fade effect for slideTo and slideNext.

If the first issue can be solved this would be good if not I may abandon using this plugin in favour of something custom. Any help appreciated.

I’ve been trying to update a program from ionic 2.0.1 to ionic 3 (angular 5) and I’m running into something that I’ve had little luck finding online.

Basically, when I run ‘ionic serve’ I get the following error -
WEBPACK_IMPORTED_MODULE_0__angular_core.OpaqueToken is not a constructor

image.png751x487 17.6 KB

and it’s coming from vendor.js (which is added to the project in the index.html file)

I did see from the angular upgrade site that all OpaqueTokens should be replaced by InjectTokens, and I tried to do directly in vendor.js… but it seems that vendor.js is created during ionic serve, so all of the changes I made are overwritten.

After reading a bunch about webpack, I imagine that the problem is that I have an import of Angular core somewhere that shouldn’t be there… but I’m unsure of what to search for. (especially because I have “@angular/core”: “5.0.1”, in my package.json file. I’m just not sure what to get rid of.
