Android Question Using webview(url) how do you do a refresh?

[John Woodsmall]

Msgbox
(target,"")

'WebView1.Initialize

WebView1.LoadUrl(target)

I run this once and it seems to get stuck. The same values are being passed to the url.

How do I force a new url to be sent?

Impossible to tell without seeing more code, can you make a small example app that fails and zip and post that.

Here is my pathfinder program. I seems to get locked-up when it call one of my on-line programs?
I call the webview function once and it then seems to call it again with the same parameter. the values
for time on the resulting chart show that the time is the same, it should change...min by min each time
you call it. It does this if you call if from the web.

thanks

There is no files folder with main.bal in the zip file.

Here it is...all of it.

It appears to be enough to call LoadURL a second time, it seems likely that the problem lies elsewhere. See attached test which updates the time when you click the button. You may have to scroll the web page to see the clock.

The problem seems to be the cache. It´s like on Windows-PC... There you can use STRG-F5 to FORCE a reload.

I have tried with you Example. You can do a usual way to force a update as workaround: call another URL each time you click on the button.

For ex.

Sub Button1_Click
    Dim dummy As Long
    dummy = DateTime.Now
    WebView1.LoadUrl(Target&"?dummy="&dummy)
End Sub

thanks for that.
I tried it ... in a number of ways.
I also tried to clear the cache on the local browser...cache/history/cookies/passwords...all
This made no difference.
Is there a way to clear the cache inside the webview function?
I have also checked the wheel out in normal browser...works fine.

 

[stevel05]

WebView does have a clearCache method you can call using JavaObject http://developer.android.com/reference/android/webkit/WebView.html

Dim JO As WebView1
JO.Runmethod("clearCache",Array As object(False))  'Use true to also clear disk files

You could try that

my bad!
I was accessing a fixed(gif) file that did not change.
I now have it working just fine!
The image is too big for the little android page. Is there anyway to
make the image smaller or the screen bigger so that you can see what
is on the page?
I turned the device around and you can see some more of it, but not the
whole thing.
