Cordova Plugin inappbrowser : How use Cordova in Cordova Webview?
Hello
I need your help for my project.
-
I installed the plugin: In App Browser https://ionicframework.com/docs/native/in-app-browser
Documentation is here: https://github.com/apache/cordova-plugin-inappbrowser -
Dynamically, I created an HTML page in this directory: this.file.dataDirectory
-
I try to load this page on the webview like this:
IMPORT
import { InAppBrowser } from '@ionic-native/in-app-browser/ngx';
CONSTRUCTOR
constructor(private iab: InAppBrowser) {}
MY CODE
const browser = this.iab.create( this.webview.convertFileSrc( this.file.dataDirectory + 'jojo/index.html' ) );
Everything is ok and there aren’t problems. My page jojo/index.html can load.
The page is load in the Cordova WebView
If I don’t mistake, because I don’t set the “target” value (the value is still “_self”) my page jojo/index.html is load in the Cordova WebView. Right ?
Reference:
So … on my page, I want to use ionic functions (or cordova functions).
How can I do that ?
My config
This is my configuration:
Ionic:
ionic (Ionic CLI) : 4.12.0 (/usr/local/lib/node_modules/ionic)

@angular-devkit/build-angular : 0.13.9

Cordova Platforms : android 7.1.4, ios 4.5.5
Cordova Plugins : cordova-plugin-ionic-keyboard 2.1.3, cordova-plugin-ionic-webview 4.0.1, (and 11 other plugins)
System:

First, remove platform by this command
ionic cordova platform rm android
Upgrade cordova-android@7 with root user
sudo npm install -g cordova-android@7
Add android platform
ionic cordova platform add android

I think you need delete node_modules folder and install again with new nodejs version.

I know the main page at https://capacitor.ionicframework.com/docs/android/custom-code/ has lots of code, but there has to be a few main command line examples that can be written in a few lines. even capacitor create --help does not give much more information and has no examples.

Ionic 3 ion-slides are not properly aligned with each other
I am trying to make a product comparison page in my ionic app. The first section should be the main specs titles (name, price, ram,…). So I figure out a way by using multiple ion-slides inside ion-slides, which worked perfectly before looping the array of products.
Here is the code:
<div>
<ion-slides slidesPerView="5">
<ion-slides slidesPerView="1" class="slideWidth" >
<ion-slide>
<ion-item class="slide_height">
<ion-label><b>Logo</b></ion-label>
</ion-item>
<ion-item>
<ion-label><b>Product</b></ion-label>
</ion-item>
<ion-item>
<ion-label><b>Company</b></ion-label>
</ion-item>
<ion-item>
<ion-label><b>Price</b></ion-label>
</ion-item>
<ion-item>
<ion-label><b>Discount</b></ion-label>
</ion-item>
<ion-item>
<ion-label><b>Final Price</b></ion-label>
</ion-item>
</ion-slide>
</ion-slides>
<ion-slides slidesPerView="2" pager paginationType="progress">
<ion-slide *ngFor="let offer of array; let i = index">
<ion-item>
<img class="brand_logo" [src]="url">
</ion-item>
<ion-item>
<ion-label>{{offer.product}}</ion-label>
</ion-item>
<ion-item>
<ion-label>{{offer.cname}}</ion-label>
</ion-item>
<ion-item>
<ion-label>{{offer.price}} $</ion-label>
</ion-item>
<ion-item>
<ion-label>{{offer.discount}} %</ion-label>
</ion-item>
<ion-item>
<ion-label>{{offer.price-offer.price*(offer.discount)/100}} $</ion-label>
</ion-item>
</ion-slide>
</ion-slides>
</ion-slides>
</div>
Here is a stackblitz. The ion-items are not well aligned with each other, between the main fix ion-slide and the others generated in a for loop.
P.S.: Using ion-grid with ion-col and ion-row produced the same effect.

Www folder is missing with ionic react app using cordova plugin
Ionic version:
ionic 4.0
Current behavior:
I am trying to create a ionic react app, using my custom cordova plugin.
I use https://ionicframework.com/blog/ionic-cli-v5-brings-react-beta-support/ to create the app. After adding cordova plugin and running ionic build/cordova prepare for ios the www folder is empty.
compared to ionic react app, if i create app for target angular it fills www folder correctly.
Expected behavior:
ionic build/cordova prepare should add desired file including index.html to www folder which is not happening fo rreact-ionic app.
Steps to reproduce:
ionic start myApp --type=react
ionic cordova plugin list
ionic cordova plugin add cordova-plugin-custom => add cordova dependencies
ionic cordova platform ios => add www folder but empty
ionic cordova build ios
ionic cordova prepare ios => www folder is still empty
ionic cordova run ios => throws an error saying www/index.html not found.
Other information:
If I execute same steps as above except first line as ionic start myApp --type=angular, it shows www folder correctly including index.html and works fine.
Ionic:
Ionic CLI : 5.0.2 (/usr/local/lib/node_modules/ionic)
Ionic Framework : @ionic/react 0.0.5
Cordova:
Cordova CLI : 8.1.1 (cordova-lib@8.1.0)
Cordova Platforms : ios 4.5.5
Cordova Plugins : cordova-plugin-ionic-keyboard 2.1.3, cordova-plugin-ionic-webview 4.1.0, (and 4 other plugins)
Utility:
cordova-res : 0.5.1
native-run : 0.2.7
System:
NodeJS : v8.10.0 (/usr/local/bin/node)
