How to overcome Chinese AndroidBOX to get PrintDocumentAdapter working?

Question

Android

There is a cheap TVBOX with Android 10.
The principle is out of focus app = unloaded from memory. elevated to absolute on it.

//create object of print manager in your device
 PrintManager printManager = (PrintManager) Objects.requireNonNull(getContext()).getSystemService(Context.PRINT_SERVICE);

//create object of print adapter
 PrintDocumentAdapter printAdapter = webView.createPrintDocumentAdapter();

//provide name to your newly generated pdf file
String jobName = "Html2Print";

 //open print dialog
 if (printManager != null) {
   printManager.print(jobName, printAdapter, new PrintAttributes.Builder().setMinMargins(new PrintAttributes.Margins(250, 250, 250, 250)).build());
}

The activity loses focus. application to debuild. The print service is crashing because it's going to fetch data to a location that doesn't already exist.

Really overcome?
