---------------------------------------------------------------
I also hit this bug, also trying to use OAuth authentication.
I tried several ways around this bug without much luck:
* With {{executeScript()}}, I received the same warning ("WebView was method
called on thread 'WebViewCoreThread'") in logcat. Tested with this code:
{quote}
var browser = window.open('http://www.google.com', '_blank', 'location=yes');
browser.addEventListener('loadstop', function (event) {
browser.executeScript(\{code: 'window.close();'\});
});
{quote}
* With {{_system}} target, the {{loadstart}}/{{loadstop}} events will not be
triggered.
* I eventually used a real URL for OAuth final redirection. It points to a
simple page asking the user to close the browser, for example:
{quote}
var browser =
window.open('http://depot.natural-solutions.eu/ImageInOsm/auth-final.html',
'_blank', 'location=yes');
{quote}
Note that calling {{window.close();}} in that page did not work,
unfortunately... It did not trigger any warning but the {{.close()}} method is
effective only when pages are opened with a regular {{window.open()}}.
If anyone can advise a better temporary workaround, it would be very nice.

Gilles
Edit:
some context: My app used to work with PhoneGap 2.5 + ChildBrowser plugin with
OAuth authentication for Flickr services. I'm now trying to migrate to latest
Cordova (I installed 3.0.4). I'm currently testing on Android emulator (API
level 18).
