Hi,

<ion-card>

               <form [formGroup]="formAddEdit">

Ionic 4 - Cordova Task :app:processDebugManifest FAILED after combine plugins

I’m trying to use Firebase Analytics and Music Controls plugins in my app, but without success.

If I start a new app and install only Firebase Analytics, when I run ionic cordova run android all works fine. The same occurs if I install only Music Controls and run the app. The only difference is that when I install the Music Controls plugin, I need to add too implementation 'com.android.support:support-v4:28.0.0' to my dependencies on build.gradle, and then all works fine too.

But, when I install Firebase Analytics and Music Controls together, and run ionic cordova run android, it returns the following error:

Task :app:processDebugManifest FAILED

Is anyone else having trouble with --background-hover on an <ion-button>? Seems other CSS custom properties work fine, but cannot seem to change the --background-hover.

My second question is should the --background-hover be changed on the button or on hover (see below)?

.button {--background-hover: blue}
.button:hover {--background-hover: blue}

Thanks in advance!

Clean-ish way to prevent content scrolling when sliding

@reedglawrence wrote:

Perhaps there is a better way to address this directly through the ionic APIs provided, however in my searches I wasn’t able to find much.

My issue is that when you slide the range slider, if you move vertically it will also scroll the page with your thumb.

My solution prevents the page from scrolling, allowing only the slider to move horizontally, while the page remains still.

HTML:
<ion-range (touchstart)="preventScroll()" (touchend)="allowScroll()"></ion-range>

Component:

  preventScroll() {
    const content = document.querySelector('ion-content');
    if (content) {
      content.style.setProperty('--overflow', 'hidden');
    }
  }

  allowScroll() {
    const content = document.querySelector('ion-content');
    if (content) {
      content.style.setProperty('--overflow', 'inherit');
    }
  }

Just figured I would contribute the solution since I found sparse answers online directly related to this functionality. I had also attempted to bind to the touchmove event and use the event.preventDefault() method to stop the page. This worked, but was less reliable than touchstart and touchend.

Hello! I am building an image gallery component. The images are provided via slotted img elements. Does stencil provide any means for programmatically accessing slotted elements? This is necessary so the gallery component can know how many images it contains and the alt text for each image. Thank you for your assistance.

I want to know how to use Events “ionLoadingWillPresent” in Ionic V4 of ion-loading.

I know the IonLoading is a Interface, here’s source code:

interface IonLoading extends JSXBase.HTMLAttributes<HTMLIonLoadingElement> {
//...
   'onIonLoadingWillPresent'?: (event: CustomEvent<void>) => void;
//...
}

But, there’s no element for IonLoading from ‘@ionic/angular’, neither for the HTML tag.

Such events like:

ionLoadingDidDismiss , ionLoadingDidPresent , ionLoadingWillDismiss , ionLoadingWillPresent .

On page: ion-loading Api

Thanks a lot.

I worked on some project with ionic v3 before and I have no problem with navigation inside modal anymore.

Now I am working on another project that use ionic v4 and I spent 2-3 days to find how to navigate inside modal. But seem like I cannot do that on ionic v4.

So I would like to know Why we cannot do that on ionic v4 ?

I am also working on iOS native application and navigation inside modal is also standard transition in iOS native application.

I am wondering why you cut this feature out, even if iOS native still have it.

We have some customer requirement to build mobile app

Summary : Customer don’t want develop mobile from scratch using any hybrid framework. They have their web site (web app) ready which can render as per different device size ( responsive ).

Points to be noted :

  1. They want us to open that web url in mobile app using in-app-browser.
  2. For login they want us to create login page where user can login and redirect to dashboard page using in-app-browser URL.(i.e after login user will redirected to in app browser )
  3. They don’t want to use angular / react for this development.

Questions

  1. Can we use vue js + cordova combination to achieve in-app-browser functionality ?
  2. is it feasible to develop such type of app ?
  3. after redirect to in-app-browser we don’t have any control on code / functionality ?
  4. also they want to change some style of html page by injecting css. which will change some UI in that page

[IONIC 4][Android] Keyboard overlaps input in form

In every form of my Android application, the keyboard overlaps the whole screen without making it scroll.
If I try to scroll the entire view manually, nothing changes.
Even adding 300px of fake height to ion-conten, through a div with a fixed height the scroll is locked.
I tried to change AndroidManifest adding the property , but nothing. Also I tried to pass config object to IonicModule.forRoot with the property scrollAssist setted true.

I dont’t understand why I have this bug only in Android app. In iOS everything works fine.
I noticed that the ion-content has --keyboard-offset setted to 0px by :host style.
The code of my view is below:
