I'm working on an android app that scans and listable device in a TextView . I'm not getting how to remove occurrence of same device again and again.

Below is the code i'm scanning devices. What amendments to make here?

private ScanCallback leScanCallback = new ScanCallback() 
 @Override
 public void onScanResult(int callbackType, ScanResult result) 
 t_c.append("Device Name: " + result.getDevice().getName()
 + " rssi: " + result.getRssi() + "n");
 

;

  @SubirKumarSao tried to maintain a list but that didn't work either. I'm an absolute noob to android.

  List allows duplicate, Set does not. Before you append just check if data already in Set. if(devicSet.contains(device)).

Answering for others.

The scan returning a device each time it finds one. There can be echo, same device found twice. OP wants to display only unique devices.

Solution:
Maintain a Set of Devices. Set data structure does not allow duplicate and solves the problem.

Once a new device is found add to deviceSet. Before adding check if device already exists. if(devicSet.contains(device)). If device already exists no-need to append to display.
