InAppBrowser cookies cleared on Android upon window close

[Giancarlo]

We are integrating our website within our mobile app. Crosswalk is being used for the WebView. There is a workflow in our app where the user is presented with a login page from our site, user logs in and is presented with some options, then the window is closed. At the end of the workflow the user is given the choice to proceed to the site or back to the app main page. This works great in iOS, the user is not prompted to login again. However, in Android, the user is unfortunately prompted to login again. Only thing I can think of is that the cookies are being cleared when close() is called on the InAppBrowser. I have tried using the Default WebView as well to no avail. Any insight would be appreciated.

Hello Giancarlo,

The InAppBrowser allows you to control the browser's and session cookie cache with a few Android-specific options:

• clearcache: set to yes to have the browser's cookie cache cleared before the new window is opened
• clearsessioncache: set to yes to have the session cookie cache cleared before the new window is opened

Can you check the values of those properties in your application. Also, if you can share a code snippet of the window.open() implementation in your project I can test its behavior further on our side.

Hi Tina,

Thanks for your reply, I was aware of the options and using them. However, there is a twist. Here is the issue, I believe this to be an InAppBrowser bug.

1) Open InAppBrowser with clearcache and clearsessioncache set to "yes".

 var myWindow = $window.open(url, '_blank', 'location=no,toolbar=no,clearcache=yes,clearsessioncache=yes,hidden=yes');

myWindow.show();

2) Start another InAppBrowser window with options omitted:

var myWindow = $window.open(url, '_blank', 'location=no,toolbar=no,hidden=yes');

myWindow.show();

That is where the problem is, you have to explicitly set the options to NO. This fixed the issue:

$window.open(url, '_blank', 'location=no,toolbar=no,clearcache=no,clearsessioncache=no,hidden=yes');
