Hello Sir.
would you kindly share your APK file with me to check it??
I'm an android apps developer, I can make login and share links working outside the web-view.
I can get your job done faster than anyone else.
as an expert android applications developer, I have interesting ideas about web-view applications.
I will be happy to discuss it with you to make your application better.
Don't hesitate to contact me.
waiting for your response.
