Create an emulator from genymotion that supports google map api. You can look this up.
Find a download for the app store that will run on your emulator. I found mine here: http://wiki.rootzwiki.com/Google_Apps#Universal_Packages_2... I was using the 4.2.2 version.
Drag and drop that into your emulator. I am using google nexus.
Say ok to the prompts.
Once everything is installed close down the emulator and restart.
sign up with a good account.
Voilà

My Android App shows the google map in debug but doesn't show it when released to the market

I have an app that I have created that uses the Google Maps and Google Playstore and in debug using Eclipse and the Android SDK the map shows up on the device I am running but when released it doesn't show up on the app. Theres just a big grey screen.

Could it be the Keystore. I have a release keystore file that was generated do I need to get the keystore from that if so how?

Are you just seeing gray screen then... it's almost definitely the API key that is wrong. The Emulator uses the debug keystore, with androiddebugkey, so you should create an API key for that. Remember to change it when you publish the app to the market
refer this

When U make your apk file. U need create a keystore. Now, using that keystore to get MD5 using "Keytool", like you did with debug keystore. After that, U need to register API key from MD5, you just got. And late, U use API key in your android manifest.

I assume it is a keystore problem.
Get the SHA1 from the keystore using the "keytool"
And register it like you did with the debug keystore.
And you are good to go.

Google Maps is showing grey tiles after publishing the apk in Play Store

I work with Google Maps Android API v2 to show some Map Fragments in my App.
Everything works until my App is published in the Play Store (I checked my exported APK before it is published and it worked just fine when sideloaded).
I have an assumption, but first the situation:
I write and sign the app (Also the API Key is from my account).
When the app is ready, another person (with another account in the Play Store) is publishing the App.
Is it possible that the API Key has to be generated from the same account that is publishing the App? I appreciate every hint!!!

Did the person publishing the app resign the APK with some other keystore?

did you generate a key for the map by using the Keystore and Alias which are used in creation of the publish apk? and after that did you give it to your mapview?

Google generates two keys, one for testing and one for production. Have you change the key to production key before compiling the apk for final release ?

Make sure all below mentioned points are taken care:
1) Wrong service was enabled. Make sure the "Google Maps Android API v2", not "Google Maps API v2" is enabled and re-generate the API key.
2) Add the following elements to your manifest. Replace com.example.mapdemo with the package name of your application.
3) Use of correct certificate and key. Release certificate, which WILL NOT WORK during debugging when you run the app on my phone. You have to use the debugging keystore certificate fingerprint instead.

Google Maps Android V2 - Blank Screen

I am implementing google maps for android. I created a test application and inserted all the permissions etc in that application and the application worked flawlessly.
But when I try and copy the same code to my real application it shows me blank screen on the android activity.Although I've updated the package name in the google api console.
Here's what my Test Project Manifest Looks Like :
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.mapstutorial"
android:versionCode="1"
android:versionName="1.0" >

android:targetSdkVersion="17" />

<uses-permission android:name="com.example.mapstutorial.permission.MAPS_RECEIVE"/>

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
and here's what my real project manifest looks like :
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

I updated the package name to com.shop.addtask in my console fingerprint but still it shows me the white screen.What could cause the problem ? The apikey I've used is same in both of the applications. But it works on test application not on the real app.
I've created the api key using the fingerprint
I've switched on google maps android v2 in the console
I am using the same api key as mentioned in the console.
So these things are correct and the problem cannot be caused by one of them.

2 possible reasons:
1. this part:
<uses-library android:name="com.google.android.maps"/>
<meta-data android:name="com.google.android.maps.v2.API_KEY" android:value="my api key"/>
should right before the closing application tag.
2. Most likely you have some sort of problem with your key. Try to generate a new by deleting the debug.keystore folder and running a project. then register it again via the console.
you can use this guide I wrote to do just that:
Google Map API V2 key
Update:
Check this for a second:
<permission android:name="com.shop.addtask.permission.MAPS_RECEIVE" android:protectionLevel="signature"/>
it looks that the package you set here is not the package of your application and should be:
<uses-permission android:name="com.shop.shoppinglist.permission.MAPS_RECEIVE"/>
<permission android:name="com.shop.shoppinglist.permission.MAPS_RECEIVE" android:protectionLevel="signature"/>

<permission android:name="com.shop.addtask.permission.MAPS_RECEIVE" android:protectionLevel="signature"/>
<uses-permission android:name="com.shop.addtask.permission.MAPS_RECEIVE"/>
package name is
package="com.shop.shoppinglist"
Hope below link helps you, AndroidManifest.xml for Google Maps Android API v2
try this,
<permission android:name="com.shop.shoppinglist.permission.MAPS_RECEIVE" android:protectionLevel="signature"/>
<uses-permission android:name="com.shop.shoppinglist.permission.MAPS_RECEIVE"/>

After everything fails, try to uninstall the app and try it again. It worked in my case.

My problem was that I've changed the app's package name in the AndroidManifest file, but not the gradle.build's "applicationId" property, maybe that helps someone...

I had the same problem. I tried everything suggested on the different solutions on this error. Inclusively, I recreated my API key(including creating a new project) and nothing worked. After many, many hours wasted, I decided to delete all myapp user data on my android device, and magically this took care of the problem. My maps display correctly! Yay!!!
Android 4.2.2: Settings/Apps/YourApp/Clear data.
I hope this simple solution helps when everything else fails.

ok, I have the same problem, I follow all the steps in the blogs and the google official page and not working, the solution is correct
<uses-library android:name="com.google.android.maps"/>
<meta-data android:name="com.google.android.maps.v2.API_KEY" android:value="my api key"/>
before close the application tag, but in the other case I found the solution, the problem is I generate SHA1 code in a macinthosh but I clone the repository and work in windows plataform but I found this problem, my solutions is that go to google console and generate other apikey but get the SHA1 code using this comand in windows,open the console
and typed this code
cd C:\Program Files\Java\jre1.8.0_20\bin and press enter
next step copy and paste this code
keytool -list -v -keystore %HOMEPATH%\.android\debug.keystore -alias androiddebugkey -storepass android -keypass android
after press enter inside the console you show the SHA1 code copy and paste in a google console,is very important specified SHA1 code ";" and correct package ..
regards!!!

I 've got a similar problem with the map. After fixing all lib and key problems, I just saw a white sreen labled with "Google".
The problem was, that I put the MapFragment into a ScrollView. After removing the ScrollView everything works fine. I can see the map.

Check whether you enabled Google Maps Android API or not
Open Google Map developer console.
Go to Library -> Google Maps Android APIs
If it is disabled, enable it.
