Hi there.

Take a look at my WebViewExtras library, specifically it's addWebChromeClient method.

Add a WebChromeClient to webView1.
The WebChromeVlient will handle console logging and javascript modal dialogs.

The default B4A WebView has no WebChromeClient.
No console messages in your javascript will ever appear in your application log.
And no javascript modals - alert(), prompt() and confirm() - will ever be displayed.

The WebViewExtras WebChromeClient passes javascript console messages to your application log and displays alert(), prompt() and confirm() modal dialogs.

I'm not sure whether a file upload dialog is part of the default WebChromeClient that that method creates, try it and report back.

If there's a way to enable a file upload dialog i can try and implement it.

Martin.

hi,

I used webviewextras addWebChromeClient method and still same problem

(thank you for reply)

It looks as though the WebChromeClient needs to implement an openFileChooser method.

It doesn't seem to be very well documented but there's a bit of info on Google: https://www.google.co.uk/search?q=android+WebChromeClient+openFileChooser&ie=UTF-8&oe=UTF-8.

I'll try and find time to investigate tomorrow.

Good news i think....

I've attached some sample code and an updated version of WebViewExtras to this post.

'Activity module
Sub Process_Globals
   'These global variables will be declared once when the application starts.
   'These variables can be accessed from all modules.

End Sub

Sub Globals
   'These global variables will be redeclared each time the activity is created.
   'These variables can only be accessed from this module.
   Dim WebView1 As WebView
   Dim WebViewExtras1 As WebViewExtras
End Sub

Sub Activity_Create(FirstTime As Boolean)
   WebView1.Initialize("WebView1")
   WebViewExtras1.addWebChromeClient(WebView1)
   
   Activity.AddView(WebView1, 0, 0, 100%x, 100%y)
   
   WebView1.LoadUrl("http://cgi-lib.berkeley.edu/ex/fup.html")
End Sub

Sub Activity_Resume

End Sub

Sub Activity_Pause (UserClosed As Boolean)

End Sub

I've tested it on the emulator (Froyo) and it seems to work ok.

Can you give it a test and report back?
Be sure to let me know what version(s) of Android you are testing with please.

Note that the attached version of WebViewExtras is just an alpha version and i'd rather you didn't use it ongoing.
As long as you report that it works ok then i'll finish off the update and get it uploaded to the libraries forum.

(Do not try to use the WebView Tag property with this alpha version - it will likely crash your application).

its indeed good new, work like sharm

many thanks for library update and help

Great i'll put the finishing touches to the update later and get it uploaded.

Be sure to get the proper update when i upload it - the version i posted earlier will cause problems if your app uses the WebView Tag property, otherwise it 'should' be ok.

I've now tidied up and optimised the update and uploaded it to the WebViewExtras thread.
