Google Maps on Android not showing anything

I got some problem when trying a google maps on android activity. When I run the project the activity doesn't show anything, only a blank activity. I try to search the solution, and try to fix it with adding a new permission like

<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES"/>

And try to change the API key with the new one. But all of them are failed. I read some solution in stackoverflow which say to MAKE SURE THE PACKAGE NAME in the credential(but this one I dont get it). Could some one help me.

Here is my activity code

package com.wahana.wahanamarketingclub.activities

import android.support.v7.app.AppCompatActivity
import android.os.Bundle
import com.google.android.gms.maps.*
import com.google.android.gms.maps.OnMapReadyCallback

import com.google.android.gms.maps.model.LatLng
import com.google.android.gms.maps.model.MarkerOptions
import com.wahana.wahanamarketingclub.R

class EventActivity : AppCompatActivity(), OnMapReadyCallback {

private lateinit var mMap: GoogleMap

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_event)
    // Obtain the SupportMapFragment and get notified when the map is ready 
to be used.
    val mapFragment = supportFragmentManager
            .findFragmentById(R.id.map) as MapFragment
    mapFragment.getMapAsync(this)
}

/**
 * Manipulates the map once available.
 * This callback is triggered when the map is ready to be used.
 * This is where we can add markers or lines, add listeners or move the 
 camera. In this case,
 * we just add a marker near Sydney, Australia.
 * If Google Play services is not installed on the device, the user will be 
 prompted to install
 * it inside the SupportMapFragment. This method will only be triggered once 
 the user has
 * installed Google Play services and returned to the app.
 */
   override fun onMapReady(googleMap: GoogleMap) {
    mMap = googleMap

    // Add a marker in Sydney and move the camera
    val sydney = LatLng(-34.0, 151.0)
    mMap.addMarker(MarkerOptions().position(sydney).title("Marker in 
    Sydney"))
    mMap.moveCamera(CameraUpdateFactory.newLatLng(sydney))
}

}
