Description

I had originally posted this on StackOverflow:
http://stackoverflow.com/questions/36395714/window-open-in-phonegap-app-on-ios-this-app-is-not-allowed-to-query-for-scheme

Not sure whether it's a Cordova or PhoneGap issue, but I use several Cordova plugins in the app, i.e. cordova-plugin-whitelist. Sorry, I'm fairly new to Cordova/PhoneGap.

I have a hybrid app developed with DevExpress and PhoneGap, using Cordova plugins.

I try to open a local jpeg image via

window.open('file:///var/mobile/Containers/Data/.../image.jpg', '_system');

but it does not work (anymore) on iPhone and iPad (latest iOS 9 version), failing with the error error:

"This app is not allowed to query for scheme file".

(The app downloaded the image beforehand via the Phonegap method FileTransfer.download to the folder that it got via

window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, ...) method.)

It works fine on Android, and it worked fine on iPhone as well a few weeks ago. I think it might be related to the PhoneGap update due to an update of DevExtreme.

Before, I used PhoneGap 3.7.0, now I use cli-5.2.0.

Using GapDebug, I see this in the log:

<Warning>: THREAD WARNING: ['InAppBrowser'] took '38.211914' ms. Plugin should use a background thread.
<Warning>: THREAD WARNING: ['File'] took '26.509033' ms. Plugin should use a background thread.
<Warning>: -canOpenURL: failed for URL: "file:///var/mobile/Containers/Data/Application/9425CCB6-77F7-4337-B37C-7DB577C2F6B4/Documents/myDocuments/a96e7238-a502-49e6-bcd3-186937afc3cb/camera_1458208164206.jpg" - error: "This app is not allowed to query for scheme file"

It's some kind of permission problem, but what to add to the config.xml?

This is my config.xml:

<widget xmlns="http://www.w3.org/ns/widgets" xmlns:gap="http://phonegap.com/ns/1.0" id="com.devexpress.apptemplate" version="1.0" versionCode="1">

  <access origin="*" subdomains="true"/>
  <gap:plugin name="cordova-plugin-whitelist" source="npm"/>
  <allow-navigation href="*" />
  <allow-intent href="*" />
</widget>

I even added the two lines

  <allow-navigation href="*" />
  <allow-intent href="*" />

according to https://github.com/apache/cordova-plugin-whitelist and it does not help.
