google maps doesnt show after upload to google play

i solved this problem finally after 3 week :D

you upload the googleplay your apk, now you have 2 different " SHA-1 ", They are "Installation certificate (your old certificate code)" and "Application signing certificate(its the new, from the googleplay")

you need to do so easy, you must add to api console your new SHA-1

First check if you have debug and release app keys. Then you have to link your api to your proyect. Apis and services (google play console). So You have to configure google play services because google maps api uses it.

I know there are diferent keys for debug and released apps. i recomend API v3 too.

Try this to register your api key.

https://console.developers.google.com/flows/enableapi?apiid=maps_android_backend&keyType=CLIENT_SIDE_ANDROID&r=24:85:5A:C0:F8:0D:36:4C:1A:B9:45:B6:21:92:B0:6E:7D:71:55:08%3Bcom.mapsapi.vatsan.googlemapsapidemo It can take some minutes. Then you have to set your google_maps_key in your android app Manifiest.

<meta-data
        android:name="com.google.android.maps.v2.API_KEY"
        android:value="AIzaSDSSDDDAAD...Your API KEY" />

If doesnt work and if you are using android studio, try creating a new Map Activity(It's V3), complete res/values/google_maps_api.xml with the key and the map gonna work. How to create google map

I can use googlemaps in my app after upload it to google play store. You have to configure Google Play Services in your google play console.
