I am blackberry developer and I don't have any experience in Android programming.

I am trying to create an android application which will have webview/embedded browser. I will load some web page with some javascripts in embedded browser. There will be some buttons on the page which will call javascript functions. Some of these functions require access to native APIs (eg Camera API). Is it possible to call native api's from javascript functions or access to native code of the app ?

Right now this is possible in blackberry platform using Javascript extension. I'm expecting something similar in Android.

Thank you.
