Also have to modify AndroidManifest.xml to grant permission of android.permission.ACCESS_WIFI_STATE.
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

And need little light and help, thnk u
hello edward,
Sorry! I have no idea how to print in Android.
Is it possible to get the RSSI of individual networks in the ScanResult list? These are not the pre-configured networks.
Please note that i need the RSSI value and not the signal strength in dBm. Thanks
Please read Check RSSI by monitoring of WifiManager.RSSI_CHANGED_ACTION
Thanks for ur reply.
But i'd wanted the following:
1. scan the available networks- which is generally done via startScan(); The results are obtained on a list.
2. get the "RSSI" value for each found-
which is my question.
A little hint/idea would do great. Thanks.
