Compatibility issues with MobileFirst Plugin for Cordova and Ionic Webview 2.x
Ionic Developers - take note! If you now create a new Ionic project and add the MobileFirst Plugin to your Ionic app, you will see that the app launches and after getting past the splash screen displays a blank white screen as seen in the screenshot below. If you’re affected by this, read on to know why this happens and how to resolve the issue.
The default WebView that is added to an Ionic project on iOS (as of today) is
email@example.com. Versions 2.x of the
cordova-plugin-ionic-webview have an issue where they do not render a page with an absolute URI. Ionic apps make use of relative URIs by default and hence are not affected by this issue. However, this issue gets surfaced in apps that have the MobileFirst plugin. This is because MobileFirst makes use of absolute URLs for the pages. This is by design of the MobileFirst SDK to enable certain features such as Direct Update.
The current solution is to simply replace the
cordova-plugin-ionic-webview plugin to the compatible version (1.2.1). To do so, navigate to the folder of your Ionic project.
Then, remove the existing
ionic cordova plugin remove cordova-plugin-ionic-webview
And add the older version of the plugin
ionic cordova plugin add firstname.lastname@example.org
Then, do a cordova prepare
ionic cordova prepare
