Hi,
I´ve a big problem with the "getScanResults()" function. I always get "0"
as result.
Here is my Code (it´s a service):
public void onCreate() {
> super.onCreate();
>
> wifiMgr = (WifiManager)getSystemService(Context.WIFI_SERVICE);
> sharedPreferences =
> PreferenceManager.getDefaultSharedPreferences(this.getApplicationContext());
> intentScan = new IntentFilter();
> intentScan.addAction(WifiManager.SCAN_RESULTS_AVAILABLE_ACTION);
> scanReceiver = new ScanReceiver();
>
> screenOnReceiver = new ScreenOnReceiver();
> registerReceiver(screenOnReceiver, new
> IntentFilter(Intent.ACTION_SCREEN_ON));
>
> screenOffReceiver = new ScreenOffReceiver();
> registerReceiver(screenOffReceiver, new
> IntentFilter(Intent.ACTION_SCREEN_OFF));
> }
>
> @Override
> public void onDestroy () {
> unregisterReceiver(screenOnReceiver);
> unregisterReceiver(screenOffReceiver);
> }
>
> @Override
> public void onStart(Intent intent, int startId) {
> wifiMgr = (WifiManager)getSystemService(Context.WIFI_SERVICE);
>
> registerReceiver(scanReceiver, intentScan);
>
> showToasts = sharedPreferences.getBoolean("checkbox_notification",
> true);
> autoSync = sharedPreferences.getBoolean("checkbox_autosync", true);
> if(wifiMgr.getConnectionInfo().getNetworkId() == -1) {
> if(wifiMgr.setWifiEnabled(true)) {
>
> if(!wifiMgr.startScan()){
> unregisterReceiver(scanReceiver);
> }
> }
> }else{
> if(showToasts)
> Toast.makeText(this.getApplicationContext(),R.string.toast_nochange,
> Toast.LENGTH_SHORT).show();
> }
> }
>
>
public class ScanReceiver extends BroadcastReceiver {
> @Override
> public void onReceive(Context context, Intent intent) {
> Log.d("wifi", "ScanComplete - "+intent.getAction());
>
> List<WifiConfiguration> wifiListSupplicant =
> wifiMgr.getConfiguredNetworks();
> List<ScanResult> wifiListScan = wifiMgr.getScanResults();
>
>
> Log.d("wifi", "LIST: "+wifiListScan.size());
} }
Somebody an idea?
Thanks"
