Elegir la imagen de la galería y la cámara a través de la carga de la vista web no funciona en Android 6.0 Marshmallow

Question

Aquí está mi código. Estoy usando WebView para fines de registro. En el proceso de registro, tengo que subir una imagen desde el dispositivo. He terminado el código para esto y está funcionando correctamente en todas las versiones de Android, excepto Marshmallow. He dado todos los permisos necesarios del manifiesto.

El código:

public class WebViewActivity extends Activity {

private static final int INPUT_FILE_REQUEST_CODE = 1;
private static final int FILECHOOSER_RESULTCODE = 1;
private static final String TAG = WebViewActivity.class.getSimpleName();
private static final int TIME_DELAY = 2000;
private static long back_pressed;
private WebView webView;
private WebSettings webSettings;
private ValueCallback<Uri> mUploadMessage;
private Uri mCapturedImageURI = null;
private ValueCallback<Uri[]> mFilePathCallback;
private String mCameraPhotoPath;

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {

        if (requestCode != INPUT_FILE_REQUEST_CODE || mFilePathCallback == null) {
            super.onActivityResult(requestCode, resultCode, data);
            return;
        }

        Uri[] results = null;

        // Check that the response is a good one
        if (resultCode == Activity.RESULT_OK) {
            if (data == null) {
                // If there is not data, then we may have taken a photo
                if (mCameraPhotoPath != null) {
                    results = new Uri[]{Uri.parse(mCameraPhotoPath)};
                }
            } else {
                String dataString = data.getDataString();
                if (dataString != null) {
                    results = new Uri[]{Uri.parse(dataString)};
                }
            }
        }

        mFilePathCallback.onReceiveValue(results);
        mFilePathCallback = null;

    } else if (Build.VERSION.SDK_INT <= Build.VERSION_CODES.KITKAT) {
        if (requestCode != FILECHOOSER_RESULTCODE || mUploadMessage == null) {
            super.onActivityResult(requestCode, resultCode, data);
            return;
        }

                return;

            }

            try {
                if (resultCode != RESULT_OK) {

                    result = null;

                } else {

                    // retrieve from the private variable if the intent is null
                    result = data == null ? mCapturedImageURI : data.getData();

Esto permitirá implementar la carga de archivos en la mayoría de las versiones, incluido el marshmellow y también probado. Pero no permite subir archivos múltiples sin embargo.

Si alguien tiene una solución para eso, sugiérala
