BuddyPress.org

I am creating a application for a website which is using WordPress with buddypress plugin.
I created a page on application which successfully login to buddypress and get all user’s data to display.

Problem is : I have a webview which redirect to user’s profile and i already asked user to enter detail in application, i don’t want user to enter details again in webview.

Please tell me some methods or functions that can be used to login through PHP
