title: Published App on Play Store can't communicate with Google Maps API and Facebook API
body: <p>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.</p>
