Android Question access google play store via webview

when i try to access google play store via webview it comes back and says:

This browser is no longer supported.

please use the Google Play Store app to access google play.


i'm trying to link from a demo app to the full version to google play using the
webview.
even if i just 'webview1.LoadURL("http://www.play.google.com")' it comes back with same text.

any ideas?

thanks.
