I searched through google about this bug and there was a fair amount of people with same problem, but all of their solutions didn't work for me.I would love for you to know that I am not experienced in asking question on this site so if you have any type of feedback on how to improve my question it will be more than welcome.Thanks.

the bug is that google map doesn't load the map and you'r left with a grey screen and the google logo on the bottom left corner.

this is my java file with the map:

package location.hive;

import android.app.Dialog;
import android.location.Address;
import android.location.Geocoder;
import android.os.Bundle;

import java.io.IOException;
import java.util.List;


public class DetailActivity extends AppCompatActivity implements OnMapReadyCallback {

    private static final int DIALOG_REQUEST = 9001;

    private GoogleMap mMap;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_detail_with_map);

        String city = getIntent().getStringExtra("city");

        setTitle(getString(R.string.landon_hotel) + ", " + city);

        Hotel hotel = DataProvider.hotelMap.get(city);
        if (hotel == null) {
            Toast.makeText(this, getString(R.string.error_find_hotel) + ": "
                    + city, Toast.LENGTH_SHORT).show();
            return;
        }

        TextView cityText = (TextView) findViewById(R.id.cityText);
        cityText.setText(hotel.getCity());

        TextView neighborhoodText = (TextView) findViewById(R.id.neighborhoodText);
        neighborhoodText.setText(hotel.getNeighborhood());

        TextView descText = (TextView) findViewById(R.id.descriptionText);
        descText.setText(hotel.getDescription() + "\n");

        if (servicesOK() && initMap()) {

            Geocoder gc = new Geocoder(this);
            List<Address> list;
            try {
                list = gc.getFromLocationName(hotel.getAddress(), 1);
                Address address = list.get(0);
                double lat = address.getLatitude();
                double lng = address.getLongitude();
                LatLng latLong = new LatLng(lat, lng);
                CameraUpdate update = CameraUpdateFactory.newLatLngZoom(latLong, 5);
                mMap.moveCamera(update);

                MarkerOptions options = new MarkerOptions()
                        .title(getString(R.string.landon_hotel) + ", " + city)
                        .position(new LatLng(lat, lng));
                mMap.addMarker(options);

            } catch (IOException e) {
                Toast.makeText(this, getString(R.string.error_finding_hotel), Toast.LENGTH_SHORT).show();
            } catch (Exception e) {
                Toast.makeText(this, e.getMessage(), Toast.LENGTH_SHORT).show();
                Log.d(this.getLocalClassName(), e.getMessage());
            }

        }

    }

    public boolean servicesOK() {
        int result = GooglePlayServicesUtil.isGooglePlayServicesAvailable(this);

        if (result == ConnectionResult.SUCCESS) {
            return true;
        } else if (GooglePlayServicesUtil.isUserRecoverableError(result)) {
            Dialog dialog = GooglePlayServicesUtil.getErrorDialog(result, this, DIALOG_REQUEST);
            dialog.show();
        } else {
            Toast.makeText(this, getString(R.string.error_connect_to_services), Toast.LENGTH_SHORT).show();
        }
        return false;
    }

    private boolean initMap() {
        if (mMap == null) {
            SupportMapFragment mapFrag = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
            mMap = mapFrag.getMap();
        }
        return (mMap != null);
    }

    @Override
    public void onMapReady(GoogleMap map) {
    }

}

and this is my app gradle file:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 26
    defaultConfig {
        applicationId "location.hive"
        minSdkVersion 21

Why has Google Maps stopped working on my phone?

Clear cache and data On your Android phone or tablet, open the Settings app. Tap Apps & notifications. Locate the Google Maps app from your list of downloaded apps. After you select the app, storage & cache options should be available.

You need to do 2 things

  1. ENABLE Google Android Maps API
  2. Add code to onMapReady and call the callback in onCreate

How to Enable Google Android Maps API

  • Login to your app in https://console.developers.google.com/
  • Click Enable APIs and Services
  • Click Google Maps Android API
  • Click ENABLE

And secondly add the following code to your DetailActivity.java,

public class DetailActivity extends AppCompatActivity implements OnMapReadyCallback {

    private static final int DIALOG_REQUEST = 9001;

    public GoogleMap mMap;

    public void onMapReady(GoogleMap map) {

        mMap = map;

        if (servicesOK() /*&& initMap()*/) {

            //Geocoder gc = new Geocoder(this);
            //List<Address> list;
            try {
                //list = gc.getFromLocationName(hotel.getAddress(), 1);
                //Address address = list.get(0);

                double lat = 0.6856979;
                double lng = 16.8795434;
                LatLng latLong = new LatLng(lat, lng);
//                CameraUpdate update = CameraUpdateFactory.newLatLngZoom(latLong, 5);
                Log.i("BEGINNING","Check this");
                mMap.moveCamera(CameraUpdateFactory.newLatLng(latLong));
                Log.i("Finishing","Check this");

                /*MarkerOptions options = new MarkerOptions()
                        .title(getString(R.string.landon_hotel) + ", " + city)
                        .position(new LatLng(lat, lng));
                mMap.addMarker(options);*/
                //onMapReady(mMap);

            } /*catch (IOException e) {
                Toast.makeText(this, getString(R.string.error_finding_hotel), Toast.LENGTH_SHORT).show();
            }*/ catch (Exception e) {
                Toast.makeText(this, e.getMessage(), Toast.LENGTH_SHORT).show();
                Log.d("Check this->", e.getMessage());
            }



        }

    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_detail_with_map);
        /*
        String city = getIntent().getStringExtra("city");
        setTitle(getString(R.string.landon_hotel) + ", " + city);
        Hotel hotel = DataProvider.hotelMap.get(city);
        if (hotel == null) {
            Toast.makeText(this, getString(R.string.error_find_hotel) + ": "
                    + city, Toast.LENGTH_SHORT).show();
            return;
        }
        TextView cityText = (TextView) findViewById(R.id.cityText);
        cityText.setText(hotel.getCity());
        TextView neighborhoodText = (TextView) findViewById(R.id.neighborhoodText);
        neighborhoodText.setText(hotel.getNeighborhood());
        TextView descText = (TextView) findViewById(R.id.descriptionText);
        descText.setText(hotel.getDescription() + "\n");
        */


        SupportMapFragment mapFrag =
                (SupportMapFragment) getSupportFragmentManager()
                        .findFragmentById(R.id.map);
//            mMap = mapFrag.getMap();
        mapFrag.getMapAsync(this);

    }

    public boolean servicesOK() {
        int result = GooglePlayServicesUtil.isGooglePlayServicesAvailable(this);

        if (result == ConnectionResult.SUCCESS) {
            return true;
        } else if (GooglePlayServicesUtil.isUserRecoverableError(result)) {
            Dialog dialog = GooglePlayServicesUtil.getErrorDialog(result, this, DIALOG_REQUEST);
            dialog.show();
        } else {
            Toast.makeText(this, getString(R.string.error_connect_to_services), Toast.LENGTH_LONG).show();
        }
        return false;
    }

//    private boolean initMap() {
//        if (mMap == null) {
//
//        }
//        return (mMap != null);
//    }
