Are you using signed api key for release mode? – Muhammad Babar Oct 08 '15 at 06:40 — Muhammad Babar, Oct 08 '15 at 06:40

Debug SHA-1 certificate fingerprint will be different from production(signed) SHA-1 certificate fingerprint , so you need to set both debug SHA-1 fingerprint and production(signed) keystore SHA-1 fingerprint for same package.

To get Keystore SHA-1 fingerprint you can use following command

keytool -list -v -keystore mystore.keystore

go to location of your keystore from terminal and replace mystore.keystore with your generated keystore.

check your package name, set both certificate fingerprint for your project package name and place API key in AndroidManifest.xml and try – Yatish Oct 12 '15 at 09:33
