    copied!<p>I am trying to scan for access points every second. Here's what I am doing. </p> <pre><code> if (isScanning()) { new Timer().schedule(new TimerTask() { @Override public void run() { results = manager.getScanResults(); manager.startScan(); } }, 0,1000); adapter.notifyDataSetChanged(); </code></pre> <p>I am displaying the results using a BaseAdapter.</p> <pre><code>public View getView(int position, View convertView, ViewGroup parent) { ScanResult result = results.get(position); if (convertView == null) { LayoutInflater inflater = (LayoutInflater) context .getSystemService(Context.LAYOUT_INFLATER_SERVICE); convertView = inflater.inflate(R.layout.network_list_row, null); } // Get textview fields TextView txtSSID = (TextView) convertView.findViewById(R.id.txtSSID); TextView txtBSSID = (TextView) convertView.findViewById(R.id.txtBSSID); TextView txtCapabilities = (TextView) convertView .findViewById(R.id.txtCapabilities); TextView txtFrecuency = (TextView) convertView .findViewById(R.id.txtFrecuency); TextView txtLevel = (TextView) convertView.findViewById(R.id.txtLevel); if (result.SSID.equalsIgnoreCase(ScanNetworks.manager .getConnectionInfo().getSSID())) { txtSSID.setText(convertView.getContext().getString( R.string.ssid_msg, result.SSID)); txtBSSID.setText(convertView.getContext().getString( R.string.bssid_msg, result.BSSID)); txtCapabilities.setText(convertView.getContext().getString( R.string.capabilities_msg, result.capabilities)); txtFrecuency.setText(convertView.getContext().getString( R.string.frecuency_msg, Integer.toString(result.frequency))); txtLevel.setText(convertView.getContext().getString( R.string.signal_level_msg, Integer.toString(result.level))); ; </code></pre> <p>I see a lot of duplicates when I display the results of the scan. I know there is an overlap between every second the startScan() is called. Is there a way I can eliminate the duplicates in the display? Also, how do I synchronize the startScan() and getScanresults() call? Please advice. Thanks</p>
