My google map app works fine on device with debug google map API KEY but when I create signed apk for my app with release google map API KEY, it does not display map. To generate release mode google API KEY , i am using SHA1 fingerprint with my keystore. And i am also defining "signing and build types" in my project Settings as explained by developer.android.com(http://developer.android.com/tools/publishing/app-signing.html).
Tried every possible solution(removing apk and than reinstalling it again, restarting the device, cleaning the project ). nothing worked. Anybody have a good solution to my problem please help. FYI Using android studios platform.
Maybe you have two google_maps_api.xml files, one in the app/src/debug/res/values folder and the other in the app/src/release/res/values folder, but only the debug one contains your API key.
