Question

After running my project, it shows blank maps, I followed many methods but still shows blank now i am confused with the map api v2,my console does not shows all api version this is my console image it does not shows all api version

This is my java file

public class MapsActivity extends FragmentActivity implements OnMapReadyCallback {

private GoogleMap mMap;
LocationManager locationManager;
LocationListener locationListener;

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    if(requestCode==1)
    {
        if(grantResults.length>0 && grantResults[0]==PackageManager.PERMISSION_GRANTED)
        {
            if(ContextCompat.checkSelfPermission(MapsActivity.this, Manifest.permission.ACCESS_FINE_LOCATION)== PackageManager.PERMISSION_GRANTED)
            {
                locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locationListener);
            }
        }
    }

}



@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_maps);
    // Obtain the SupportMapFragment and get notified when the map is ready to be used.
    SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
            .findFragmentById(R.id.map);
    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.

@Override
public void onMapReady(GoogleMap googleMap) {
    mMap = googleMap;
    locationManager=(LocationManager)this.getSystemService(Context.LOCATION_SERVICE);
    locationListener=new LocationListener() {
        @Override
        public void onLocationChanged(Location location) {
            LatLng myplace = new LatLng(location.getLatitude(),location.getLongitude());
            mMap.addMarker(new MarkerOptions().position(myplace).title("veraval").icon(BitmapDescriptorFactory.
                    defaultMarker(BitmapDescriptorFactory.HUE_RED)));
            mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(myplace,20));

        }

        @Override
        public void onStatusChanged(String provider, int status, Bundle extras) {

        }

        @Override
        public void onProviderEnabled(String provider) {

        }

        @Override
        public void onProviderDisabled(String provider) {

        }
    };


        if (ContextCompat.checkSelfPermission(MapsActivity.this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) {

            ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, 1);
        } else {
            Toast.makeText(MapsActivity.this,"hello",Toast.LENGTH_LONG).show();

            locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locationListener);

        }



}

Please see https://developers.google.com/maps/documentation/android-api/start for how to correctly set up the map.
Ensure API KEY exists in your app:
- Go to Google Console Credential Manager. and add android API key for debug and release. Check Google Doc for more details.

build.gradle

buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            resValue "string", "google_maps_api_key", "Release_API_KEY"
        }
        debug {
//          KL MBP debug Key
            resValue "string", "google_maps_api_key", "DEBUG_API_KEY"
//          KL Old Machine debug Key
//            resValue "string", "google_maps_api_key", "DEBUG_API_KEY"
        }
    }

AndroidManifest.xml

<meta-data
    android:name="com.google.android.maps.v2.API_KEY"
    android:value="@string/google_maps_api_key"/>

<uses-library
    android:name="com.google.android.maps"
    android:required="true" />

Check my answer for more details on how to setup API key google_maps_api_key and add to build.gradle as release or debug.

Update 1

Easy way to setup Google Maps API key.
To get one, follow this link, follow the directions and press "Create" at the end:

https://console.developers.google.com/flows/enableapi?apiid=maps_android_backend&keyType=CLIENT_SIDE_ANDROID&r={SHA-1}%3B{YOUR_APP_PACKAGE_NAME}
- Ex:
  
  https://console.developers.google.com/flows/enableapi?apiid=maps_android_backend&keyType=CLIENT_SIDE_ANDROID&r=08:F2:4F:C5:43:3E:4E:B7:30:71:0F:06:F1:9F:85:F5:E2:1D:B8:73%3Bcom.lelasoft.googlemapv2

Note: It may take up to 5 minutes for settings to take effect

Update 2

I created new MapActivity and it works with me after setup API key using Update 1 instruction and it take about 5 minutes to take effect

Update 3

Set Android emulator GeoLocation

Update 4

Ask user to enable GeoLocation on device.

build.gradle

dependencies {
     // Other dependences 
    implementation 'com.google.android.gms:play-services-location:15.0.1' // add location dependency.

Be careful that API key that you add to Google Console take up to 5 minutes for settings to take effect. — Khaled Lela, Jul 26 '18 at 06:17
Check my **Update** >> Easy way to setup Google Maps API key — Khaled Lela, Jul 26 '18 at 06:28
I ve added the api key in debug/res/values as well as release/res/values — aksishere, Jul 26 '18 at 06:56
Try to create new project with `MapActivity` and follow instruction. I just create new one and map worked with me after setup API key and it take about 5 minutes to take effect, Updated my answer with map screen. — Khaled Lela, Jul 26 '18 at 07:01
Did you follow instructions on **Update 1**, Please ensure you correctly put `your_package_name` & SHA-1 to the link. — Khaled Lela, Jul 26 '18 at 07:07
Check my testApp on [Github](https://github.com/KhaledLela/GoogleMapV2Test) — Khaled Lela, Jul 26 '18 at 07:20
I've followed all the instruction, checked my package name and SHA-1 key many times but the problem is still there. — aksishere, Jul 26 '18 at 11:54
@aksishere If my answer helped you to fix your issue, Don't forget to accept it. — Khaled Lela, Jul 26 '18 at 13:29
Thank you ,I am trying too hard to solve the issue, still not solved, if it solved I'll surely mark it. — aksishere, Jul 26 '18 at 14:03
My marker is not showing on the specified position, what would be the reason — aksishere, Jul 26 '18 at 14:19
This means that your `GeoLocation` is not opened on your device, Check my [Github example](https://github.com/KhaledLela/GoogleMapV2Test/blob/master/app/src/main/java/com/lelasoft/googlemapv2/MapsActivity.java) to know how to ask user to enable GeoLocation on device. — Khaled Lela, Jul 26 '18 at 21:45
Check my **Update 4**, hope that help you to fix your issue and learn how to ask user for enable GeoLocation, Have a nice day! — Khaled Lela, Jul 26 '18 at 21:58
Bro u just rocked it thank you so much for this valuable ans, been searching this for like three days — aksishere, Jul 27 '18 at 15:49
