i am trying to set up my laptop as an access point for my Android to use WiFi, so i knew that ubuntu sets the network as Ad-Hoc which is not discoverable by android, So i tried the method explained here -which i found on many other websites- but when i run hostapd.conf this error appears :

nl80211: Failed to set interface wlan0 into AP mode nl80211 driver initialization failed. ELOOP: remaining socket: sock=4 eloop_data=0x8e488f8 user_data=0x8e48ea0 handler=0x807c5e0 ELOOP: remaining socket: sock=6 eloop_data=0x8e4aca8 user_data=(nil) handler=0x8086770

this is how my hostapd.conf looks like :

   interface=wlan0
    driver=nl80211
    ssid=Any_SSID_name 
    hw_mode=g
    channel=1
    macaddr_acl=0
    auth_algs=1
    ignore_broadcast_ssid=0
    wpa=2 
    wpa_passphrase=Any_password
    wpa_key_mgmt=WPA-PSK
    wpa_pairwise=TKIP
    rsn_pairwise=CCMP

and this is my wireless card info :
