android- google map stop working

I've used google maps in my application since 8 month ago . I'm using eclipse. It works nice and every thing was ok. Now I find out that maps are not showing anymore , it shows the google icon and zoom icons too but it doesn't show the maps .
I went to new google developer console . https://console.developers.google.com and I enabled Google Maps Android API on the console , then I went to "credential" and regenerate a new key .
I change some codes in manifest , this is my manifest code :
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<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.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<permission
android:name="myapplication.permission.MAPS_RECEIVE"
android:protectionLevel="signature" />
<uses-permission android:name="ir.persiandesigners.jazebehayeiran2.MAPS_RECEIVE" />
<uses-feature
android:glEsVersion="0x00020000"
android:required="true" />
<!-- end map -->
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/CustomActionBarTheme" >
<meta-data
android:name="com.google.android.geo.API_KEY"
android:value="myApiKey" />
<meta-data
android:name="com.google.android.gms.version"
android:value="#integer/google_play_services_version" />
I export the app and installed it again but it doesn't work yet .
what should I do ? Why it is not working ?
by the way ,I'm having google play service lib verion 4.3.23 in the eclipse and I'm sure that I've installed google play service on my phone .
thanks

When you export the app did you use another key other than debug.keystore. Then you should generate the SHA1 key with the keystore file you used to export the app.

<meta-data android:name="com.google.android.gms.version"
android:value="#integer/google_play_services_version"/>
<meta-data android:name="com.google.android.maps.v2.API_KEY"
android:value="your_API_key"/>
<meta-data android:name="com.google.android.gms.version"
android:value="google_play_services_system_key"/>
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES"/>
"google_play_services_system_key" this will you get in your error when you run your code. this is your system key put that here.

Try to Open your SDK manager and Update the Google Play Services and Google Repository.

Is READ_GSERVICES permission still required for Google Maps?

To add Google Maps to your android application, you need to include a few permissions:
<!-- Required -->
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<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"/>
<!-- Optional -->
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
However, by checking Google Maps Android API v2 documentation again, I noticed that
com.google.android.providers.gsf.permission.READ_GSERVICES
is no longer required. I tested it by removing it from AndroidManifest.xml and the map is loading fine without any problems.
So, my question is.. what is/was the purpose of READ_GSERVICES permission?
Note: Even though it is removed from Google Maps Android API v2 documentation, it can be found on
Google Maps API for Business documentation.

All permissions you need for Google Maps Android API are in the docs:
You must also request the android.permission.WRITE_EXTERNAL_STORAGE permission.
Note: If you're targeting the Android M SDK (23) and the latest version of the Google Play services SDK (8.1), you no longer need the WRITE_EXTERNAL_STORAGE.
From the next release of the Google Play services SDK, the requirement for the WRITE_EXTERNAL_STORAGE permission will be completely dropped from the Google Maps Android API.
So the answer is NO, you don't need it if you use current latest GPS, i.e. 8.1.0.

NO, This persimmons is no longer required in google MAP API V2
<permission
android:name="phonelocation.example.asuss550c.phonelocation.permission.MAPS_RECEIVE"
android:protectionLevel="signature" />
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />
You only need to add
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
Also this MetaData in your Application Tag
<meta-data
android:name="com.google.android.geo.API_KEY"
android:value="#string/google_maps_key" />

LogCat error
Google Maps Android API﹕ Failed to load map. Error contacting Google servers. This is probably an authentication issue (but could be due to network errors).

Check your API key carefully
Check your SHA key carefully
You should be connected to internet using WIFI before first time using Google map and wait 2-3 min till download map data etc. next time no need to connected with internet but if u want to search another location it must also be connected with internet using WIFI .

By seeing the LogCat error
Google Maps Android API﹕ Failed to load map. Error contacting Google servers. This is probably an authentication issue (but could be due to network errors).
it seams its problem with Authentication. and Code should have
googleMap = fm.getMap();
// Getting reference to the SupportMapFragment of activity_main.xml
SupportMapFragment fm = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
// Getting GoogleMap object from the fragment
googleMap = fm.getMap();
Try to use this... And Double check SHA1 key
EDIT :
Check Phone Location settings also..

Try these:
Google Play Services:
You have to download the latest Google Play Services
com.android.vending-4.8.20.apk.In that site if google play
services wasn't working means you can find a lot of sites in
internet named com.android.vending 4.8.20.apk.
you can run the Google play Services by using the Command Prompt
adb install com.android.vending 4.8.20.apk.
Note: You have to download the latest Google play services because year by year latest version will be updated in internet.

Authorization Failure in Google Maps Android V2

When I try to debug my project I got this error using debug certificate
I already ensure that my package name and SHA-1 corresponds to my api key
Here's my AndroidManifest.xml

Here's my API KEY
Here's my SHA-1 certificate
I got my SHA-1 using eclipse
By the way I'am using real device in debugging my project, c#, visual studio 2012 and xamarin.android. It only displays white screen with google logo and zoom in and out button. What's wrong with my debug certificate?

If the key is new ( has just been created in Google APIs Console ) it will take some time for it to be available to Google Maps.
Don't worry everything is declared OK, it just takes some time.
Edit : By what is written in the log looks like you have to add the fingerprint for your debug key store : D9595..
Just add a new line in Google APIs console with that fingerprint . Your debug keystore is found at C:\Users\.android\debug.keystore and the default password is : android

Titanium SDK: The Google Play services resources were not found

I'm currently working on getting an old Titanium SDK 1.x app working in the modern era on Titanium SDK 3.1.2.
One of the challenges I've managed to find myself stuck on is after upgrading from Google Android Maps API v1 to v2 I'm consistently getting this error:
The Google Play services resources were not found. Check your project configuration to ensure that the resources are included.
I have installed in the ADK the 18.0.1 build tools as well as the required Google Play Services extras package. Uninstalling/reinstalling does nothing useful, and as far as I can tell there's no way to manually include the Play Store Services library in Titanium.
For reference I followed the instructions here to set up the Maps API v2 in the app. The following is what is in my tiapp.xml file (I replaced the actual package names):
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES"/>
<uses-feature android:glEsVersion="0x00020000" android:required="true"/>
<uses-permission android:name="com.example.permission.MAPS_RECEIVE"/>
<permission android:name="com.example.permission.MAPS_RECEIVE" android:protectionLevel="signature"/>
<application>
<meta-data android:name="com.google.android.maps.v2.API_KEY" android:value="###"/>
<uses-sdk android:minSdkVersion="10" android:targetSdkVersion="10"/>
</application>
Note that the correct certificates and correct API have been used within the Google API Console.
Does anyone have any idea why I might be unable to load the Google Play Services in my Titanium app?
Thanks in advance!

The maps only work on device. Are you running this in the emulator?
I have an additional permission set "android.permission.ACCESS_NETWORK_STATE"
Also double check to ensure your appId is correct and matches what is in your tiapp.xml file

This is more of a suggestion than an answer but I got the same error and it made me bark up the wrong tree for quite some time before I realized I had an error somewhere else in the code. In my case, there was a view element that had a null attribute, though that wasn't clear from the stack trace. The Play Services error you pasted above was visible early on but it seems that the compiler will ignore it if the service is found.
:(
To make matters more confusing, I built the same code for iOS and there was no error.
