So this is what ive done so far..
Create a webview app that shows a fb sign-in page on my website. I was able to add views dynamically during Fb sign-in as showed in Making facebook login work with an Android Webview . Everything was working fine (in kitkat- where i usually test my code).
Then, I observed some time ago that in lollipop devices- on clicking the signin button- although a new tab is created and signin occurs successfully, the parent webview is not getting the successful sign-in info.(??). It is still displaying a 'please sign in message'.
I read in some blog long ago that this is a bug in FB api(although im not sure i understood it correctly), and it will be fixed. Has anyone else had the same problem?? .Thanks for ur time. P.S. My code is similar to the one in the link i referred above.
