If you're not calling methods on Profile, you can just forward declare "class
Profile" and not include the header.

[lshang, 2016/09/21 03:47:39]

Still need this after we change to get Profile from WebContents:-)

[dominickn, 2016/09/20 08:01:36]

Nit: I think you still need this header for CONTENT_SETTINGS_TYPE_*

[lshang, 2016/09/21 03:47:39]

Done.

Don't add the Profile* argument here. Instead, call
Profile::FromBrowserContext(web_contents->GetBrowserContext()) in the
MediaStreamInfoBarDelegateAndroid constructor. That way, you don't need to
change the PermissionBubbleMediaAccess file.

Done. Get Profile from WebContents.
