I followed this tutorial: How can I create an Android application in Android Studio that uses the Google Maps Api v2?
And I compiled and get sample maps application running on my device. The only problem is that maps dont display in my application, all I got is blank screen.
My AndroidManifest.xml (all i changed is apikey)
<?xml version="1.0" encoding="utf-8"?>

I created key in console using my debug fingerprint, it looks like this:

Logcat for maps:
08-03 02:41:14.330 13942-14784/com.example.mapdemo I/Google Maps Android API: Failed to contact Google servers. Another attempt will be made when connectivity is established.
08-03 02:41:29.840 13942-14812/com.example.mapdemo E/Google Maps Android API: Failed to load map. Error contacting Google servers. This is probably an authentication issue (but could be due to network errors).
