How to resend POST data when using WebView.goBack(

问题:

I am working on an application where we are providing user with the option to navigate back to the webpages user has previously viewed.

The problem arises when user navigates back to a page which contained POST data.

I don't know how to detect that the page loaded in the WebView had POST data so that app can prompt a confirm dialog, if he wants to resend the POST data or not.

I have seen this happening in android browsers [Native browser & Skyfire]

Thanks in advance...

After several days of research I created a workaround to get rid of this situation.

I set a flag when WebView.goback() is called.

In my onProgressChanged() method I check if the url being loaded matches with the url which should contain the POST DATA, then I call WebView.reload(), I set my flag to false and I also override the onFormResubmission method of the WebViewClient this way:

@Override
public void onFormResubmission (WebView view, Message dontResend,Message resend){
    resend.sendToTarget();
}
