I have found that there is a significant lack of documentation of
WebView's ability to communicate with Java via WebView.addJavaScript()
method. First, the debug document
http://developer.android.com/guide/developing/debug-tasks.html#DebuggingWebPages
appears to no longer work. Second, what object types should we expect
when going to and from JavaScript. I have done some trial and error
and it appears that complex types can cross the boundary, for example
java.util.Vector. However when a Java method returns a byte array to
JavaScript it has a type of undefined and I have been unable to coerce
it to any other type. Finally, there is great potential with this
interface and with some more attention we could go far.
