Fixed: Apps (Cordova/PhoneGap) targeting LOLLIPOP or later default to disallowing third party cookies

When I ported a Cordova app to Android 5 (Lollipop), I noticed, that the login does not work anymore. In prior versions of Android it works like a charm (app login is based on session cookies).

Part of the Android Lollipop changes:

Apps that target KITKAT or below default to allowing third party cookies. Apps targeting LOLLIPOP or later default to disallowing third party cookies.

Android 5.0 changes the default behaviour for your app.
If your app targets API level 21 or higher:
The system blocks mixed content and third party cookies by default. To allow mixed content and third party cookies, use the setMixedContentMode() and setAcceptThirdPartyCookies() methods respectively.
The system now intelligently chooses portions of the HTML document to draw. This new default behaviour helps to reduce memory footprint and increase performance. If you want to render the whole document at once, disable this optimization by calling enableSlowWholeDocumentDraw().
If your app targets API levels lower than 21: The system allows mixed content and third party cookies, and always renders the whole document at once.

Indeed, if the app rely on session cookies it will stop working as expected.

However. Here is a fix to make session cookies work again on Android Lollipop and above:

BTW: Make sure that you use the latest Android SDK to compile the source code. I have also created an issue at the Cordova bug tracker (https://issues.apache.org/jira/browse/CB-8026).
