android - Published App on Play Store can't communicate with Google Maps API and Facebook API

Question

I created a signed APK with Android Studio, and I added to Google Developer console and Facebook console my SHA1 fingerprint and the relative api keys in my app. Everything works well if I upload my signed apk via USB, after installing it maps API and facebook api works well. If I upload the same apk to the Play Store, when I try to login with Facebook, it says "invalid key hash. The key hash blablabla doesn't match with any stored..". So if I log without facebook, I can't even get my google maps; this leads me to think that the apk loaded on the play store changes his fingerprint or some stuff like that. I checked all the stuff on Android Developers and Stackoverflow, but I can't make it work, because the strange thing is that this signed release apk works well until I load it on the Play Store.

Answer 1

With inspiration from @Andy Developer, I could display the map after my app was uploaded to Google Play. These were the steps:

1. Upload your app to Google Play (signed APK file)
2. After the app has been submitted and approved, select your app from Google Play Console
3. Go to Development Tools -> Release management -> App signing

4. Copy the first SHA-1 certificate which Google Play has issued after uploading the app.
5. Go to Google Console and select your project.
6. Select your API-key, restrict your key, and paste the SHA-1 after package name.

7. Press Save, wait a couple of mins. and your app should show Google Maps.
