Google map API key not working properly in android app but IP address works properly

Question

Downloaded URL: { "error_message" : "This IP, site or mobile application is not authorized to use this API key. Request received from IP address 000.00.000.00, with empty referer", "routes" : [], "status" : "REQUEST_DENIED"}

i got this Error when i put SHA-1 and Package name to generate key , key generated but when i use it and run application some times it works limited (PlaceAutoComplete work) but on selection No Response and some times PlaceAutoComplete Also not works (when i write a single character PlaceAutoSearch option went closed),

if i give IP address of my device it works properly with tha same nothing to b change , just need to change google map API key settings from Android to IP address

Why it asked for IP authorization? why it not works on SHA-1 and Package name in Android
