wordpress with android

Hi there
.I’m working in Android app.which have a website & a forum.

from my phone app. I can access the website & then I can go to the forum.Also from my app I can do forum signup ” no need signup for website”
and at the android App. I need to show the post, comment, and view the posts page from the forum.
All of the three “App. website, forum” share a single data base.
but my question is I have seen a video integrating wordpress with Simple Press Forum “I think it’s a plugin”
SO I wonder if that will help me in
1- creating the website.
2- integrating a forum into the website so they will have same background ” template”.
3- import some specific pages from the forum into the android APP.
I need to show some forum pages in my phone app.

I hope you can get me some help coz I’m really stuck.

I tired to use a website & integrate PHPBB forum into that website but I got error including PHP code into HTML files.

Thanks a lot
