What's wrong with google map API v2?

Question

This issue is common BUT I didn't find a solution on google, or stackoverflow (4days of research...)

Here is the thing :

I need to display a full screen google map, which i ve already done several times in other application i've developped. BUT here i can't get it to work for an unknow reason !

The warning and the error i get when i open the SherlockFragmentActivity which contains the map :

The Google Play services resources were not found. Check your project configuration to ensure that the resources are included.

---

Failed to load map. Error contacting Google servers. This is probably an authentication issue (but could be due to network errors).

Here i'll explain how i did things in detail and post some code :

LIBRARY IMPORT :

Last version of Google play services imported in eclipse as library (checked) In the project the google play services are imported as library in properties (like ABS)

MANIFEST :

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="pck name"
    android:versionCode="1"

                <intent-filter>
                    <action android:name="android.intent.action.MAIN" />

                    <category android:name="android.intent.category.LAUNCHER" />
                </intent-filter>
            </activity>

... activities...

        </application>

    </manifest>

MAP LAYOUT :

<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/map"
    android:name="com.company.pckgname.TransparentSupportMapFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

ACTIVITY :

public class ActivityGoogleMap extends SherlockFragmentActivity implements OnInfoWindowClickListener {

        GoogleMap                   _googleMap;

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_maps);
        // ABS
        ActionBar bar = getSupportActionBar();
        bar.setTitle(R.string.tle_map);
        bar.setDisplayHomeAsUpEnabled(true);
        // MAP
        _googleMap = ((TransparentSupportMapFragment) getSupportFragmentManager().findFragmentById((R.id.map))).getMap();

 //the map should still display at this point
        }
    }

And so that's it, the main code is here

The map was working up until now, i didn't do nything with the code map related...

I tried to regenerate a debug key on the google console, change the permissions .. etc i am out of idea !!!!

After changing the API key in AndroidManifest.xml you must clear application data.

To clear application data do one of the following:

• Go to Settings > Application Manager > Select Your Application > Clear Data
• Uninstall the application before re-installing it.
