The title says it all. I would like to know about everything what the WebView is asking for. Some weird limitations like not knowing about XHR POST are not acceptable. In other words, something like iOS have in NSURLProtocol. That one is application-wide hook. I don't need such level of control, WebView-instance-specific hook would be good enough. Now, i know that nothing like that exists on Android out of the box. I know about shouldOverrideUrlLoading and shouldInterceptRequest, but it's largely unusable. I need to know about requests (method, HTTP version, headers, you know) not just merely the URL strings. Moreover the intercepting is awkwardly synchronous. What happens if shouldInterceptRequest call is blocked because i need to ask a different server for related resource? It appears to me being designed just for a local resource caching.
On the other hand, i am willing to throw anything at the problem. Some kind of native library, hooking into low level internals? Extending Chromium interfaces with help of an existing project (pwnall, mogoweb)? Reflecting into the existing webkit class privates? Application-specific proxy? Any insights appreciated. I have read through two dozens of existing SO questions. They all either suggest a partial hack (like working around XHR POST deficiency with JavaScript) or it goes unresponded altogether, very often.
