Я использую приведенный ниже код для загрузки файла в webView:

    @SuppressLint("SetJavaScriptEnabled")
    private void loadWebView(String url) {
        if (getActivity() != null) {

            if (Build.VERSION.SDK_INT >= 23 && (ContextCompat.checkSelfPermission(getActivity(), Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED || ContextCompat.checkSelfPermission(getActivity(), Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED)) {
                ActivityCompat.requestPermissions(getActivity(), new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE, Manifest.permission.CAMERA}, 1);
            }

            WebSettings webSettings = webViewRequest.getSettings();

            webSettings.setLoadsImagesAutomatically(true);
            webSettings.setJavaScriptEnabled(true);
            webViewRequest.clearHistory();
            webViewRequest.setHorizontalScrollBarEnabled(false);
            webViewRequest.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);

            webSettings.setAllowFileAccess(true);
            webSettings.setJavaScriptCanOpenWindowsAutomatically(true);
            webSettings.setSupportMultipleWindows(true);


            webViewRequest.loadUrl(url);

            if (Build.VERSION.SDK_INT >= 21) {
                webSettings.setMixedContentMode(0);
                webViewRequest.setLayerType(View.LAYER_TYPE_HARDWARE, null);
            } else if (Build.VERSION.SDK_INT >= 19) {
                webViewRequest.setLayerType(View.LAYER_TYPE_HARDWARE, null);
            } else if (Build.VERSION.SDK_INT < 19) {
                webViewRequest.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
            }
            webViewRequest.setWebViewClient(new Callback());

                            progressRequestWebView.setVisibility(View.GONE);
                        }
                    }

            });
        }
    }

    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent intent) {
        super.onActivityResult(requestCode, resultCode, intent);
        if (Build.VERSION.SDK_INT >= 21) {
            Uri[] results = null;
            //Check if response is positive
            if (resultCode == Activity.RESULT_OK) {
                if (requestCode == FCR) {
                    if (null == mUMA) {
                        return;

                    if (intent == null) {

                        if (mCM != null) {
                            results = new Uri[]{Uri.parse(mCM)};
                        }
                    } else {
                        String dataString = intent.getDataString();
                        if (dataString != null) {
                            results = new Uri[]{Uri.parse(dataString)};
                        }
                    }
                }
            }
            mUMA.onReceiveValue(results);
            mUMA = null;
        } else {
            if (requestCode == FCR) {
                if (null == mUM) return;
                Uri result = intent == null || resultCode != Activity.RESULT_OK ? null : intent.getData();
                mUM.onReceiveValue(result);
                mUM = null;
            }
        }
    }

    public class Callback extends WebViewClient {
        public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
            Toast.makeText(getActivity(), "Failed loading app!", Toast.LENGTH_SHORT).show();
        }
    }

    private File createImageFile() throws IOException {
        @SuppressLint("SimpleDateFormat") String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
        String imageFileName = "img_" + timeStamp + "_";
        File storageDir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES);
        return File.createTempFile(imageFileName, ".jpg", storageDir);
    }

    @Override
    public void onConfigurationChanged(Configuration newConfig) {
        super.onConfigurationChanged(newConfig);
    }

И мне нужно использовать приведенный ниже код, когда пользователь касается любой ссылки в webView, но не работает:

webViewRequest.setWebViewClient(new WebViewClient() {

                @Override
                public void onPageStarted(WebView view, String url, Bitmap favicon) {
                    super.onPageStarted(view, url, favicon);
                    if (url.contains("GetAttachment")) {
                        cookies = CookieManager.getInstance().getCookie(url);
                        urlDown = url;
                        if (checkPermission()) {
                            startDownload(urlDown, cookies);
                        } else {
                            requestPermission();
                        }
                    }
                }
});

Я удаляю ниже строки и хорошую работу сейчас:

webSettings.setJavaScriptCanOpenWindowsAutomatically(true);
webSettings.setSupportMultipleWindows(true);
