Android web view Block URL by Whitelist

#1

Hi friends,

I have been frustrated by running my app on android. I use latest cordova-plugin-ionic-webview (3.1.2) and have proper whitelisting in my config file. But when I launch my app on android device, it seems like all my external URLs get blocked:

02-09 12:05:01.071 31101-31223/com.ionicframework.fitopedia341280 W/SystemWebViewClient: URL blocked by whitelist: https://MYAPP.appspot.com/BLAH/

Here is my Ionic Info:

Ionic:

   ionic (Ionic CLI)  : 4.10.2 (/usr/local/lib/node_modules/ionic)
   Ionic Framework    : ionic-angular 3.9.2
   @ionic/app-scripts : 3.2.0

Cordova:

   cordova (Cordova CLI) : 8.1.2 (cordova-lib@8.1.1)
   Cordova Platforms     : android 6.4.0, ios 4.5.5
   Cordova Plugins       : cordova-plugin-ionic-keyboard 2.1.3, cordova-plugin-ionic-webview 3.1.2, (and 12 other plugins)

System:

   Android SDK Tools : 26.1.1 (/Users/behrooz/Library/Android/sdk/)
   NodeJS            : v9.11.1 (/usr/local/Cellar/node/9.11.1/bin/node)

   OS                : macOS Mojave
   Xcode             : Xcode 10.1 Build version 10B61

and here is my cordova info including config.xml:

Note everything is fine on IOS. And I think I this is prolly since I moved to ionic-cordova-web-view. Any help is much appreciated.

I fixed the problem by removing plugins folder. I think what was happening was that my cordova plugin got updated and the whitelisting part used to be part of cordova itself in the past and now it’s seperate, somehow some caching mess was happening even though I removed the platforms folder many time. The trick is anytime to do anything with damn cordova to remove everything and start from scratch.
