List Wifi without enabling location service

Question

While developing an app where I scan the WiFi, I found that it does not work if I turn off the location service on my phone. I have provided the app with all the necessary permissions. - ACCESS_NETWORK_STATE, ACCESS_WIFI_STATE, ACCESS_COARSE_LOCATION.

This is my code:

WifiManager manager= (WifiManager) getApplicationContext().getSystemService(Context.WIFI_SERVICE);
manager.startScan();

In the receiver:

int found = manager.getScanResults().size();

This question answers part of the problem. Wifi scan results broadcast receiver not working

My questions are:

1. Is there a way for the app to list the Wifi access points if the location service is turned off?

2. If location service is absolutely necessary, is there a way for the app to turn on the location service while the app scans the wifi access points?

Answer 1

The only way to get the scanResult without GPS turned on is to set the app's targetSDKversion to 21 or lower.

This will work even on Lolipop and above.
