Question 1

How to migrate from cordova-plugin-ionic-webview 2.x to 5.x?

Accepted Answer

Follow the migration guide: remove and re-add the plugin, ensure android-minSdkVersion is set to 21 if using older cordova-android, and replace normalizeURL() with convertFileSrc() for file handling. Update URL schemes in config.xml as default origins have changed.

Question 2

What is the difference between WKWebView and UIWebView in Cordova?

Accepted Answer

WKWebView is Apple's modern WebView with better performance, security, and standards support, while UIWebView is deprecated and slower. This plugin uses WKWebView on iOS to enhance app speed and compatibility, unlike Cordova's default.

Question 3

How to display local images in Ionic WebView?

Accepted Answer

Use the window.Ionic.WebView.convertFileSrc() method to convert local file paths to URLs that the WebView can render, as direct file or content protocols may not work due to scheme restrictions.

Question 4

Is cordova-plugin-ionic-webview compatible with Capacitor?

Accepted Answer

No, Capacitor has its own built-in WebView implementation, so this plugin is unnecessary for Capacitor apps. It's designed specifically for Cordova and Ionic Framework projects using Cordova.

Question 5

Why is my app showing a white screen after installing the ionic webview plugin?

Accepted Answer

This often stems from incorrect URL scheme configuration. Verify that allow-navigation entries in config.xml match the set Hostname and Scheme preferences, and ensure the WebView can load from the configured origin.

Question 6

What are the performance benefits of using ionic webview over default Cordova webview?

Accepted Answer

It leverages WKWebView on iOS and the evergreen WebView on Android, offering faster JavaScript execution, improved memory management, and support for modern web APIs, leading to smoother app experiences in hybrid apps.
