There are some things you need to check:

1. Is the SHA1 fingerprint is ok that you have registered in google api console.For how to find it , you can find it here

2. The generated api_key must be same with the menifest.

3. Name of the app in api console must be same with the name of app in strings.xml.

4. meta-data must have to be included in menifest.

<meta-data 
             android:name="com.google.android.gms.version"
             android:value="@integer/google_play_services_version" />

For google map to work add below lines to your manifest -

<meta-data 
             android:name="com.google.android.gms.version"
             android:value="@integer/google_play_services_version" />

and import google play service library to your workspace.
