Try a worldwind:// link for example.

This doesn't crash the app for more, but it does cause it to just sit there with the spinner spinning until you press back or go to another page.

This is also sort of an iOS bug, as when you click the link on iOS nothing happens, which is pretty bad considering the user has no idea why the link isn't loading; the fact the link is meaningless isn't obvious to you from the text that displays.

A message saying that displays the link and says that the app can't handle it would probably be the best solution for iOS and Android.

Still crashing for me .. latest Google Play alpha release.

Is this still the case? I can't find any link that crashes the app.

Testing in a moment...
