Why does the WebViewDemo die?

Question

I copied this WebViewDemo demo verbatim from the official Google site.

Yet, the moment I click on that little Android image, the application dies (instead of making raise its hand):

Why? Is the bug in the demo itself? (I can't believe I am the first one to discover that) or is it a bug in my own development environment setup?

Answer 1

From: phonegap.js crashes android app

This is a bug with 2.3.x. simulator - Javascript->Java bridge is bugged.

The Google bug specifically uses this demo code. http://code.google.com/p/android/issues/detail?id=12987

Go star it so they know to fix it soon.

You can workaround this for now by just using a 2.2 emulator.
