Question

I want a HTML/javascript application, running in a WebView to make AJAX calls that are handled by the Java code.
Ideal would be to just intercept the call (easy, just use shouldOverrideUrlLoading()) and ‘return’ some data.
However, I don’t find a way to ‘return’ a response to the WebView, other than calling a javascript function using loadUrl().
This will not work for me, as the HTML/javascript app is a drop-in application which I don’t control. As far as the HTML/javascript app concerns, it just does an AJAX call and receives some data back.

Any thoughts on this?

Answer 1

In the end I used the method described in the question anyway;

I intercepted some specific requests like: foo://bar/get/1?callback=foobar then parsed the URL and called a javascript callback function with the actual data.
The callback function was defined in the query-part of the URL, so in the above example that would be: foobar();

Calling that function was easy, just use: yourWebView.loadUrl("javascript:foobar('somedata')");
