I have noticed the same behavior using the built in browser, and am looking
for a solution right now also. I am just in the process of creating 10 or 15
web pages for mobile apps, and this has me stopped right now.
If I find it I will let you know, but if anyone has the solution, it would
be appreciated.
Sincerely,
Brad Gies

Subject: [android-developers] Re: WebView html form POST problem
Hi, Fred. Thanks for reply.
Page loads inside current Activity. It does not open new browser
window ( this is exactly what I wanted it to do ).
Basically, its like implementing your own browser -> everything is
handled by WebView inside my app.
My problem is that WebView does not make POST request of an empty form
twice.
Here is paraphrased and step by step explanation of the problem.
My WebView loads the page from http://mydomain.com/example.php
The example.php has a form with one input text box <input type="text"
name="mytextbox"> and a submit button <input name="mybutton"
type="submit" value="Submit">.
This form is set to submit the data to itself (<form action="http://
mydomain.com/exmaple.php" method="POST">)
1) My app loads example.php with loadURL("http://mydomain.com/
example.php")
2 I click submit button -> my app makes post request and gets the same
page back, so I see the form again.
3) I click submit button again -> my app just sits there without
making any requests to the server any more.
4) I click again and again -> nothing happens.
5) I put some text in input text box and form starts working again,
meaning it submits the page to the server again.
So, I suspect that it has something to do with caching mechanism but I
am not sure.
Any ideas? Please let me know if you observed the same behavior
(solved or not solved :-)
If someone tries to replicate the situation please let me know how it
goes.
Thanks again everybody!
