WebView or open in a browser for user guide

In an android app I have user guide section, where some helpful info is shown to the user. These helpful information are in form of web pages. So I am planning to show web content to the user. I could do this in two ways

• Using a webview, where web pages shown inside app itself.

  • con: needs to request internet permission from the user

• Ask user to open it in a browser.

  • con: may need to select a browser if there are multiple browsers installed.

Which is preferred and why?
