How to get scan result from wifi for example every 3 seconds, without mWifimanager.startScan();
Google says :
startScan()
This method was deprecated in API level P. The ability for apps to trigger scan requests will be removed in a future release.
Notice for this API level i'm using
List<ScanResult> results = mWifiManager.getScanResults(); without calling startScan , the list contains the wifi AP's but it makes updated very very slow
Update to 12 January 2019 : https://issuetracker.google.com/issues/112688545
Google has now documented the limitations for startScan() function in Android P:
"We are further limiting the number of scans apps can request to improve network performance and improve battery life.
The WifiManager.startScan() usage is limited to: - Each foreground app is restricted to 4 scans every 2 minutes. - All background apps combined are restricted to one scan every 30 minutes."
