How to intercept POST data in an android webview

Question

I have an android app that consists of a webview. It needs to allow users to fill in a form on a webpage and then change the data of the form after the user has clicked

Answer 1

I wrote a library with a special WebViewClient that offers a modified shouldOverrideUrlLoading where you can have access to post data.

Unfortunately, my implementation works for XMLHttpRequest (AJAX) requests only. But somebody else drafted already how this would be done for form data: https://github.com/KeejOow/android-post-webview

Between the two repositories, you should be able to find your answer :)
