Android Question [B4XPages] Upload files with WebView

[Mike1970]

Hi everyone,
In my project I have a WebView that loads a webpage that has a "Choose File" button.
I took a look in the forum and i found this post: Upload files with WebView

However... the attached project works, but it's not b4xpages...
As soon as i take the code (and the manifest too) to put it in my project (B4Xpages) it does not work any more, fails compiling with this error in the Java part

src\xxx\xxx\home.java:9887: error: cannot find symbol
        processBA.raiseEventFromUI(this, "showfile_chooser", filePathCallback, fileChooserParams);
        ^
symbol:   variable processBA
location: class MyChromeClient

How can i solve the problem?
There is another approach to open the file chooser from a webview?

Thanks in advance
