Hostapd shows wlan0: AP-ENABLED, But SSID not Visible in Devices

Question

I am running hostapd on android devices on adb shell with following command.

hostapd -B /data/misc/wifi/hostapd.conf

it gives me following log

04-04 12:33:23.276  3052  3052 E hostapd : Using interface wlan0 with hwaddr 00:0a:f5:33:62:98 and ssid "SSID"

04-04 12:33:23.398  3052  3052 I hostapd : wlan0: interface state UNINITIALIZED->ENABLED

04-04 15:36:35.520  3046  3046 D hostapd : ctrl_iface not configured!

I assume, hostapd is running properly. But I am not able to see the SSID in any Station or Device.

Also one more thing, ignore_broadcast_ssid is set to 0 in hostapd.conf which showcases that SSID is not hidden

I also knew that, Some DNSMASQ related configuration needs to be done. But I think SSID be visible on any Station or Device before that configuration.

Can anyone point me what am i doing wrong?

I had this problem with Raspberry Pi 3. The problem was collision of wpa_supplicant with hostapd on Stretch. Solved by disabling wpa_supplicant with hostapd. Citing Roger James:

adding the following line to to the relevant WLAN interface stanzas in /etc/dhcpcd.conf.

nohook wpa_supplicant

e.g.

interface wlan0
nohook wpa_supplicant
static ip_address=192.168.0.1/24
