// implement WebChromeClient inner class
        // we will define openFileChooser for select file from camera
        webView.setWebChromeClient(new WebChromeClient() {

            // openFileChooser for Android 3.0+
            public void openFileChooser(ValueCallback<Uri> uploadMsg,
                    String acceptType) {
                /** updated, out of the IF **/
                mUploadMessage = uploadMsg;
                /** updated, out of the IF **/
                Log.e("Reac", "**Here");
                try {
                    File imageStorageDir = new File(base_directory,
                            "profile_pictures");
                    if (!imageStorageDir.exists()) {
                        imageStorageDir.mkdirs();
                    }
                    src_file = new File(imageStorageDir + File.separator
                            + "IMG_" + child_id + ".jpg");
                    mCapturedImageURI = Uri.fromFile(src_file); // save to the
                                                                // private
                                                                // variable

                    final Intent captureIntent = new Intent(
                            android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
                    captureIntent.putExtra(MediaStore.EXTRA_OUTPUT,
                            mCapturedImageURI);

                    startActivityForResult(captureIntent,
                            FILECHOOSER_RESULTCODE);
                } catch (Exception e) {
                    Toast.makeText(getBaseContext(), "Camera Exception:" + e,
                            Toast.LENGTH_LONG).show();
                }
            }



            // openFileChooser for Android < 3.0
            public void openFileChooser(ValueCallback<Uri> uploadMsg) {
                openFileChooser(uploadMsg, "");
            }

            // openFileChooser for other Android versions
            public void openFileChooser(ValueCallback<Uri> uploadMsg,
                    String acceptType, String capture) {
                openFileChooser(uploadMsg, acceptType);
            }

            /** Added code to clarify chooser. **/

            // The webPage has 2 filechoosers and will send a console message
            // informing what action to perform, taking a photo or updating the
            // file
            public boolean onConsoleMessage(ConsoleMessage cm) {
                onConsoleMessage(cm.message(), cm.lineNumber(), cm.sourceId());
                return true;
            }

            public void onConsoleMessage(String message, int lineNumber,
                    String sourceID) {
                // Log.d("androidruntime", "Per cÔøΩnsola: " + message);
            }
            /** Added code to clarify chooser. **/

        });

I added only piece of code. Please ask me if any details required.

It seems there is a known bug in Android 4.4 that make <input type="file"> not work inside a WebView.

Unfortunately openFileChooser is not a public API and there is not a public support for that. In Android Lollipop has been introduced the API onShowFileChooser for this purpose.

My suggest is to workaround the problem using the JavaScript native WebView interface and define a custom openFileChooser API handled by the native part of your App.
