It's just NOT working.
I'm doing this
webView.setWebChromeClient(new WebChromeClient() {
        public void openFileChooser(ValueCallback<Uri> uploadFile) {
            System.out.println("openFileChooser");
            mUploadMessage = uploadFile;
            Intent i = new Intent(Intent.ACTION_GET_CONTENT);
            i.addCategory(Intent.CATEGORY_OPENABLE);
            i.setType("file/*");
            PresentationActivity.this.startActivityForResult(
                    Intent.createChooser(i, "Image Browser"),
                    FILECHOOSER_RESULTCODE);
        }
    });
but openFileChooser is never called. Any ideas? openFileChooser is marked @hide in Android source code. I think its because you should NOT use this method. Is there another possibility to open a fileChooser??
