Download file via BLOB link in Android webview

I have a website that is navigated from within a webview. One of the pages generates a ZIP file that is downloaded via a BLOB URL. I discovered that this is not supported by webview, so I have tried implementing this solution:
Download Blob file from Website inside Android WebViewClient
However, it is not working for me. Breakpoints in convertBase64StringToZipAndStoreIt are never hit.
UPDATE: I've found that I'm getting an HTTP 404. I've tried using blobUrl and blobUrl.substring(5) and the result is the same either way. The BLOBs are downloading fine in Chrome, though.
Webview setup:
private void launchWV() {
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE},
1);
setContentView(R.layout.activity_self_service_launcher);
mWebView = (WebView) findViewById(R.id.activity_launcher_webview);
WebSettings webSettings = mWebView.getSettings();
webSettings.setBuiltInZoomControls(true);
webSettings.setSupportZoom(true);
webSettings.setJavaScriptEnabled(true);
webSettings.setJavaScriptCanOpenWindowsAutomatically(true);
webSettings.setSupportMultipleWindows(true);
webSettings.setAllowContentAccess(true);
webSettings.setAllowFileAccess(true);
webSettings.setAllowFileAccessFromFileURLs(true);
webSettings.setUserAgentString("Mozilla/5.0 (Android; X11; Linux x86_64) AppleWebKit/534.24 (KHTML, like Gecko) Chrome/11.0.696.34 Safari/534.24" + getClientVersionInfo());
webSettings.setDomStorageEnabled(true);
webSettings.setLoadWithOverviewMode(true);
mWebView.setWebViewClient(new MyWebViewClient(this));
mWebView.setWebChromeClient(new MyWebChromeClient(this));
mWebView.addJavascriptInterface(new JavaScriptInterface(getApplicationContext()), "Android");
}
Function called from shouldOverrideUrlLoading() (only the else condition for BLOB URLs is of concern):
private boolean handleRequest(WebView view, String url) {
String filename;
if (!checkInternetConnection()) {
ShowNetworkUnavailableDialog(false);
return true;
}
else {
if (url.contains("view/mys") || url.contains("view/myy") || url.contains("blob") || url.contains("view/mye")) {

} else if (url.contains("view/myy")) {

}
if (!url.contains("blob")) {

String currentDateTime = DateFormat.getDateTimeInstance().format(new Date());
final File dwldsPath = new File(Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_DOWNLOADS) + "/YourFileName_" + currentDateTime + "_.zip");
byte[] zipAsBytes = Base64.decode(base64Zip.replaceFirst("^data:application/zip;base64,", ""), 0);
FileOutputStream os;
os = new FileOutputStream(dwldsPath, false);
os.write(zipAsBytes);
os.flush();
if(dwldsPath.exists()) {
NotificationCompat.Builder b = new NotificationCompat.Builder(context, "MY_DL")
.setDefaults(NotificationCompat.DEFAULT_ALL)
.setWhen(System.currentTimeMillis())
.setSmallIcon(R.drawable.ic_launcher_background)
.setContentTitle("MY TITLE")
.setContentText("MY TEXT CONTENT");
nm = (NotificationManager) this.context.getSystemService(Context.NOTIFICATION_SERVICE);
if(nm != null) {
nm.notify(notificationId, b.build());
Handler h = new Handler();
long delayInMilliseconds = 5000;
h.postDelayed(new Runnable() {
public void run() {
nm.cancel(notificationId);
}
}, delayInMilliseconds);
}
}
}
}
One thing I know I am unclear on is what URL should be going into the call to xhr.open in the class.
I also tried using onDownloadStart with the same result.
Any insight is greatly appreciated!

I want to print to pdf file in javascript, where outputstream and pdfwriter

I am trying to create a PDF from a server-side controller (report) (ireport) with ajax (and so on), and try to return the data to pdfwriter, servletoutputstream, and httpservletresponse. (I do not know exactly what I'm doing, but I'm doing it this way).
The original purpose was to send a server-side pdf file to the client, find the printer and print without a preview window.
Among them, I wrote 'application / pdf' on the server side and 'datetype: text' on the client side ajax (there is an error if I do not use ajax datatype: text)
If you print the results to the console, they will only be listed as unknown code.
Currently I am trying to put it into an iframe frame.
Question!
1. What should I do to use the text string sent to server -> client as pdf or script code?
(I have already asked you two weeks ago)
2. How do I send a pdf to server -> client? I would like to apply it to the screen by expressing it directly in code instead of downloading it. To print out.

dataType : "text",
type: "POST",
contentType: 'application/json; charset=utf-8',
async : false,
success: function(result){
// I want to view PDF contents and directly print to PDF.

Read data like serial number,Time stamp from two RFID RC522 readers connected to Raspberry Pi

Can someone please help me how to read serial number ,Time stamp from two rfid readers connected to Raspbery Pi.There are some solutions in python, c# .Net but not in javascript.
I am trying to ímplement with Node Js but did not find any helpful resources for reading data from two rfid readers.
Many Thanks in advance

To read the data from multiple RFID readers you could use the following:
1. For reading the data from node:
There are a few projects out there reading that involve reading RFID tags from node, e.g. here and here.
Additionally also some npm packages, e.g. rfidreader.
There are even ones that are especially for RC522, e.g. rc522-c7z
2. For multiple readers:
Every reader should be provided by a unique serial port. This needs to be passed to the code from step 1.

this is a sample for windows 10 uwp app on raspbbery pi. you must be carefull using asynchronous programming on uwp consept.
