So problem is: I open webview url with form and when I press back, it goes back to the same page. I think it is related to form resubmission. What can I do? Maybe there is an override for form resubmission handling in WebViewClient or WebChromeClient that I am not aware of? I cannot just handle url manually, because in my case it would be close to impossible to handle each possible case.

Here is my back logic?

@Override
public boolean onBackPressed() {
    if (webView.canGoBack()) {
        webView.goBack();
        return true;
    }
    return false;
}

how it act in browser? – Jiang YD Oct 30 '15 at 09:07
It asks about form resubmission. – Heisenberg Oct 30 '15 at 09:12
seems browser know the history is a form submit, but web view not know it. i suggest to use ajax and control the url location in js, if you have the control of web pages. – Jiang YD Oct 30 '15 at 09:18
Unfortunatelly I do not. This is banking page's web page. – Heisenberg Oct 30 '15 at 09:21
you may take a look on [this](http://stackoverflow.com/questions/9460720/how-to-resend-post-data-when-using-webview-goback-method) – calvinfly Oct 30 '15 at 09:29
You can detect the URL and take an action accordingly. – Skynet Oct 30 '15 at 09:34
@Skynet so do some hack of keeping old url and then looking if url points to the same place, setting some flags, etc. instead of some elegant solution? – Heisenberg Oct 30 '15 at 09:36
What kind of onBackPressed is that? The method onBackPressed in Activity class does not return a boolean – Mister Smith Oct 30 '15 at 09:45
No its not a hack, check `onPageFinished(WebView view, String url)` - read up on this and you will understand what I mean. If that does not fit your needs, you are better off doing this the `Native` way. Apps are not websites! – Skynet Oct 30 '15 at 09:48
