In iOS, there have been two webviews for a few years now, UIWebView and WKWebView. Historically, Ionic apps have used UIWebView, but no longer. Ionic now uses WKWebview by default when building for iOS. We strongly believe WKWebview is the best option for any app, as it features many improvements over the older, legacy webview (UIWebView). These features include: 1. JIT conversion of JS code down to machine code, which runs much faster 2. Improved rendering performance 3. Less memory consumption 4. Better adherence to web standards 5. Reliable scroll events (important for virtual-list) We wanted to make sure that people could easily switch to WKWebView without many issues, but there are still some things that you’ll need to consider. Update Ionic CLI WKWebView plugin needs latest Ionic CLI in order to work properly. Please make sure that your global CLI is using the latest 3.x release. If not, please upgrade: npm uninstall -g ionic npm install -g ionic Upgrading to...

Update 01/15/2020 : On December 23rd, 2019, Apple clarified plans for UIWebView: “The App Store will no longer accept new apps using UIWebView as of April 2020 and app updates using UIWebView as of December 2020.” Please follow the instructions below to either update to a newer version of Cordova or migrate to Capacitor. Update 11/25/2019 : The Cordova team has released Cordova iOS 5.1.0 , which disables UIWebview at compile time.

Flutter makes use of the Dart packaging system, pub. Via your applications  pubspec.yam l file (or simple pubspec), you can pull down packages from the flutter ecosystem, or the broader dart community. Anyway, i need to add some images to my flutter application, and so had to add an assets section to the pubspec .the default Android Studio generated apps pubspec has a lot of commented out code with explainations about what is going on, e.g # To add assets to your application, add an assets section, like this: # assets: # - images/a_dot_burr.jpeg # - images/a_dot_ham.jpeg # An image asset can refer to one or more resolution-specific "variants", see # https://flutter.io/assets-and-images/#resolution-aware. So I uncommented these lines # assest : - - - #  -  images/a_dot_ham.jpeg with the idea from these comment.  that i would just edit it to suit my particular needs. Once you have edited your  pubspec, you need to click on the "Get dependenc...

Android HTTP request not working in Android Pie  Recently I faced a weird situation where my app was working fine in all Android versions except Android Pie. After lots of debugging I came to know it was because my server was not secure ie it was using HTTP (not HTTPS). Android P uses HTTPS by default. What this means is that if you are using unencrypted HTTP requests in your app, the app will work fine in all versions of Android except Android P. Let’s consider two situations where your app won’t work properly in Android P. Firstly, if your server is on HTTP obviously it won’t work in Android P. Another case is when your server is on HTTPS but it is returning something like an image URL which is HTTP, you won’t be able to load the image in Android P. The good news is… there is a really simple and quick fix for the above problem so let’s get started. You just need to create a  network_security_config   file in the xml folder and then include it in the manif...
