google map showing blank in genymotion

问题

I am using Google Nexus 4.2.2 - with Google API on Genymotion. The google maps fragment is coming up empty. I have registered with the API and providing the key in the manifest file. Thanks for your help.

Layout:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MapsTestActivity" >

    <fragment
       android:id="@+id/map"
        android:name="com.google.android.gms.maps.MapFragment"
        android:layout_width="match_parent"
        android:layout_height="0dp"/>

</RelativeLayout>

Activity:

package com.chaseit.activities;

import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;

import com.chaseit.R;
import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapFragment;
import com.google.android.gms.maps.model.BitmapDescriptorFactory;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.Marker;
import com.google.android.gms.maps.model.MarkerOptions;

public class MapsTestActivity extends Activity {

    static final LatLng HAMBURG = new LatLng(53.558, 9.927);
    static final LatLng KIEL = new LatLng(53.551, 9.993);
    private GoogleMap map;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_maps_test);
        // setupMap();
    }

    @Override
    protected void onResume() {
        // TODO Auto-generated method stub
        setupMap();
        super.onResume();
    }

    private void setupMap() {

        GoogleMap map = ((MapFragment) getFragmentManager().findFragmentById(
                R.id.map)).getMap();

        Marker hamburg = map.addMarker(new MarkerOptions().position(HAMBURG)
                .title("Hamburg"));
        Marker kiel = map.addMarker(new MarkerOptions()
                .position(KIEL)
                .title("Kiel")
                .snippet("Kiel is cool")
                .icon(BitmapDescriptorFactory
                        .fromResource(R.drawable.ic_launcher)));

        // Move the camera instantly to hamburg with a zoom of 15.
        map.moveCamera(CameraUpdateFactory.newLatLngZoom(HAMBURG, 15));

        // Zoom in, animating the camera.
        map.animateCamera(CameraUpdateFactory.zoomTo(10), 2000, null);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.maps_test, menu);
        return true;
    }

}

I got the example code from http://www.vogella.com/articles/AndroidGoogleMaps/article.html

Inorder to use google maps v2 in our android application, one must use google-play-services library. This Library works only if context is passed to check whether services is available to that devices. Add this line in your oncreate

GooglePlayServicesUtil.isGooglePlayServicesAvailable(getApplicationContext());

Comment me about the result

Check the output log, search on maps, and see if warnings notices come up. In my case, I found:

09:03:34.197 E/Google Maps Android API( 7012): Authorization failure.  Please see https://developers.google.com/maps/documentation/android-api/start for how to correctly set up the map.
03-22 09:03:34.198 E/Google Maps Android API( 7012): In the Google Developer Console (https://console.developers.google.com)
03-22 09:03:34.198 E/Google Maps Android API( 7012): Ensure that the "Google Maps Android API v2" is enabled.
03-22 09:03:34.198 E/Google Maps Android API( 7012): Ensure that the following Android Key exists:

Double check on the following:

That you gave the correct SHA1 fingerprint of your application in google developer console (For me, somehow this changed)
That you gave the correct package name
That you included they API key in the manifest file (Obvious, yes, I know)
That the proper permissions are also set in manifest ACCESS_COARSE_LOCATION ACCESS_FINE_LOCATION ACCESS_LOCATION_EXTRA_COMMANDS ACCESS_MOCK_LOCATION
If using an emulator, insure that Google Play Services (including Maps) is installed.

In my case , I did not find a solution,the map is blank when it is opened and navigating the map does nothing , but I had a PlaceAutocompleteFragment and when i use it to search for a place I move the map to that place and it works , the map is now shown and you can navigate it . you don't have to use PlaceAutocompleteFragment you can just get around the problem by moving the camera to a place you want when the map loads and then navigate from there , this can be done by adding this to the onMapReady() function :

LatLng latLng = new LatLng(15.501501,32.4325101) ;// change to the value you want
float zoom = 15.0f;
mapfragment.getMap().moveCamera(CameraUpdateFactory.newLatLngZoom(latLng, zoom));
