Question

I have a register page that has a file upload button on it. This is a aspx page in C#.

When i run it in a browser it works fine.
When i run it in a web view in an android app it does not launch the file menu in you android phone.
When i run the page in a browser on my android phone it lanuches the file menu on my phone just fine.

How do i get it to work in a web view.

My asp tag.

<asp:FileUpload ID="FileUpload1" runat="server" Height="30px" Width="217px" />

my android web view

case R.id.register:            
mWebView2 = (WebView) findViewById(R.id.webview);    
mWebView2.getSettings().setJavaScriptEnabled(true);    
mWebView2.loadUrl("www.mysite.com/AndroidAddMember.aspx");
mWebView2.setWebViewClient(new HelloWebViewClient());           
return true;  

I tried to implement your code that you suplied. Im getting an error on FILECHOOSER_RESULTCODE now.
The error is FILECHOOSER_RESULTCODE cannot be resolved to a variable.

case R.id.register:            
        //mWebView2 = (WebView) findViewById(R.id.webview);    
        //mWebView2.getSettings().setJavaScriptEnabled(true);    
        //mWebView2.loadUrl("http://www.bangmeornot.com/AndroidAddMember.aspx");
        //mWebView2.setWebViewClient(new HelloWebViewClient());   
        mWebView2.setWebChromeClient(new WebChromeClient()   
        {   
            //The undocumented magic method override   
            //Eclipse will swear at you if you try to put @Override here   
            public void openFileChooser(ValueCallback<URL> uploadMsg) {   

            ValueCallback<URL> mUploadMessage = uploadMsg;   
            Intent i = new Intent(Intent.ACTION_GET_CONTENT);   
            i.addCategory(Intent.CATEGORY_OPENABLE);   
            i.setType("image/*");   
            BangMeorNot.this.startActivityForResult(Intent.createChooser(i,"File Chooser"), FILECHOOSER_RESULTCODE);        
            }   
        });   

        return true;

Apparently the stock browser uses an undocumented method to accomplish file uploads. Here’s what you have to do to enable this functionality in your app:

mWebView2.setWebChromeClient(new WebChromeClient()  
{  
    //The undocumented magic method override  
    //Eclipse will swear at you if you try to put @Override here  
    public void openFileChooser(ValueCallback<Uri> uploadMsg) {  

    mUploadMessage = uploadMsg;  
    Intent i = new Intent(Intent.ACTION_GET_CONTENT);  
    i.addCategory(Intent.CATEGORY_OPENABLE);  
    i.setType("image/*");  
    MyAwesomeActivity.this.startActivityForResult(Intent.createChooser(i,"File Chooser"), FILECHOOSER_RESULTCODE);       
    }  
});  

Note: The exact parameters for this function have changed throughout the various versions of Android. For a solution which works across all Android versions, check out this question, or try using the parameters listed in this answer.
