My question is very simple. when device OS was Lolipop or kitkat or jellybean, i could get Wi-fi scan result in background without Location service well.(it means Location service turn off) after OS upgrade to 6.0 Mashmallow, it doesn't work.
if i turn on the location service, i can get Wi-fi scan result in background on Android 6.0.
why it doesn't work? and How i can get Wi-fi scan result in Background on 6.0.
