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);

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());
webViewRequest.setWebChromeClient(new WebChromeClient() {
@Override
public void onProgressChanged(WebView view, int newProgress) {
super.onProgressChanged(view, newProgress);
if (newProgress == 100) {
if (progressRequestWebView.getVisibility() == View.VISIBLE) {
progressRequestWebView.setVisibility(View.GONE);
}
}
}

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();
}
}
}
});
