Google Maps API V2 'Failed to Load Map. Could not contact Google Servers', Even I check permission and keystore

I follow the guide to create a google map sample,

but it always throw following error.

E/Google Maps Android API(27821): Failed to load map.  Could not contact Google servers.

permission READ_GSERVICES and debug and release keystore have been tested. They also can't resolve above problem. Could anyone tell me why it throw that error?

Manifest file:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

Check permissions

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-feature
    android:glEsVersion="0x00020000"
    android:required="true" />

<permission
    android:name="com.packagename.permission.MAPS_RECEIVE"
    android:protectionLevel="signature" />

I had same problem! Reinstalled it 50 times. Just clear cache and remove all data for application on Android device before deleting. It helps, thanks to Gods...

Don't forget to clear program cache before trying new API KEY :) Because Android is using first API key even if you change API key.

I had a similar issue as user2204477. I had 

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

It should be

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

Note the wrong one says "permissions" and the correct one says "permission". I just wasted 5 hours trying to figure this out lol.

I had same problem. After creating API key a lot of time,the problem still exists. Then i simply uninstall the application and installed it again.basically the application is storing wrong api key credentials in the cache memory.And when we rerun the the app,It just loads it from cache.So installing the application again solves my problem.

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.

I solved this problem by adding Support to my fragment on the layout class: 

class="com.google.android.gms.maps.SupportMapFragment"

did you added all the other need permissions?

<permission android:name="com.eadesign.skygiraffefinalv2.permission.MAPS_RECEIVE" android:protectionLevel="signature"/>
<uses-permission android:name="com.eadesign.skygiraffefinalv2.permission.MAPS_RECEIVE"/>
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

UPDATE:

1. The meta-data part should be at the most lower part of the application tag, like so:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.where.common"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="16" />
<permission
    android:name="com.where.common.permission.MAPS_RECEIVE"
    android:protectionLevel="signature" />
<uses-permission android:name="com.where.common.permission.MAPS_RECEIVE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.com.google.android.providers.gsf.permission.READ_GSERVICES" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-feature
    android:glEsVersion="0x00020000"
    android:required="true" />
<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name="com.where.common.MainActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

<meta-data
        android:name="com.google.android.maps.v2.API_KEY"
        android:value="AIzaSyDawEkMP7gdiB4nOOkXcdUcxSAvm0kfCmI" />
</application>

2. another problem I see is that you develop your application for API V8, so you have to use the SupportMapFragment and FragmentActivity for your Activity.

3. and last thing for your Map to work you have to add an License activity for Google Licensing info.

Did you solve the problem? May be this is the problem ->

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. (https://stackoverflow.com/a/13805807/1300982)

If this is the problem, do not forget to Regenerate the API Key.

Finally, I find why this would happen. Because I write

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

It is wrong. It should be 

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

Here I thanks for Emil Adz's patience to help me!
