Android V10 New | Winsoft Nfcnet Library For

The landscape of Android development has changed. With the evolution of the .NET ecosystem and the fragmentation of Android API levels, developers need tools that are not just compatible, but optimized for the future. Winsoft NFCNet Library for Android v10 is here to answer that call.

Gone are the days of wrestling with native Android SDK wrappers and inconsistent .NET bindings. Version 10 represents a significant leap forward, rebuilt to align with the latest Android standards and the modern .NET unification.

Android 10 introduced scoped storage and stricter runtime permissions. The new NFCNet v10 seamlessly adapts to these changes. The library now handles ACCESS_FINE_LOCATION permission (required for NFC scanning on Android 10) automatically, with built-in dialogs and fallback mechanisms. winsoft nfcnet library for android v10 new

Fix: Enable reader.setLegacyMifareWorkaround(true) in v10—this is a new property that active retries with corrected bit timings.

If your goal is to write tags, the process is similar but you must format the data into TNdefMessage. The landscape of Android development has changed

procedure TMainForm.WriteToTag;
var
  Msg: TNdefMessage;
  Rec: TNdefRecord;
begin
  if not Nfc1.Active then Exit;
// Create a Record
  Rec := TNdefRecord.Create;
  Rec.Tnf := tnWellKnown; // Type Name Format
  Rec.Text := 'Hello World'; // Helper property (Newer library versions handle payload encoding)
// Create a Message container
  Msg := TNdefMessage.Create;
  Msg.AddRecord(Rec);
// Write logic usually happens inside the OnTag event or immediately after detection
  // Assuming you have a detected 'CurrentTag' variable:
  // CurrentTag.WriteNdefMessage(Msg); 
end;

public class NFCScanner 
    private NFCNetReader reader;
    private Activity activity;
public void start(Activity act) 
    this.activity = act;
    reader = NFCNet.getInstance().getReader(act);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) 
        reader.enableForegroundDispatch();
     else 
        reader.enable();
reader.setReaderCallback(new NFCNetReader.ReaderCallback() 
        @Override
        public void onTagDiscovered(TagInfo tagInfo) 
            String uid = bytesToHex(tagInfo.getUid());
            Log.i("NFC", "UID: " + uid);
// Example: read NDEF if present
            Ndef ndef = Ndef.get(tagInfo.getTag());
            if (ndef != null) 
                try 
                    ndef.connect();
                    NdefMessage msg = ndef.getNdefMessage();
                    // process NDEF
                 catch (IOException e)
@Override
        public void onError(Exception e) 
            Log.e("NFC", "Error", e);
);
private String bytesToHex(byte[] bytes) 
    StringBuilder sb = new StringBuilder();
    for (byte b : bytes) sb.append(String.format("%02X", b));
    return sb.toString();

One standout feature is the ability to use external USB NFC readers via USB host mode (OTG). This is critical for enterprise applications where built-in NFC range is insufficient. The v10 new version includes drivers for popular readers like ACR122U, SCL3711, and HID Omnikey.

| Issue | Solution | |-------|----------| | No tag detection in background | Use foreground dispatch + activity in foreground | | MIFARE Classic fails | Ensure screen unlocked; try reader.enableReaderMode() | | HCE not responding | Add android:requireDeviceUnlock="false" in XML | | Multiple tags detected | Use reader.setMaxTags(1) | | Battery drain | Disable reader in onPause() |
