Answer 1

as described at the bottom of that link; http://developer.android.com/google/play-services/setup.html

and here comes sample code to handle this properly;

int checkGooglePlayServices =    GooglePlayServicesUtil.isGooglePlayServicesAvailable(mContext);
    if (checkGooglePlayServices != ConnectionResult.SUCCESS) {
    // google play services is missing!!!!
    /* Returns status code indicating whether there was an error. 
    Can be one of following in ConnectionResult: SUCCESS, SERVICE_MISSING, SERVICE_VERSION_UPDATE_REQUIRED, SERVICE_DISABLED, SERVICE_INVALID.
    */
       GooglePlayServicesUtil.getErrorDialog(checkGooglePlayServices, mActivity, 1122).show();
    }

Answer 2

Download and install the latest Google Play services from the Play Store. For some reason, I couldn't find it by searching. By running the sample app from the SDK in the folder /extras/google/google_play_services/samples/maps I was prompted to install the upgrade and was taken to the Play Store to do that.

Answer 3

I had the same problem in my project. The solution is very simple just handle the possibility that ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMap(); can return null. If you will handle null the buid-in SupportMapFragment will handle Google Play services out of date. error and will show you insted of map localized message and button for updating the Google Play Service just like this that @qubz is telling about in sample project.

Code from sample:

@Override
protected void onResume() {
    super.onResume();
    setUpMapIfNeeded();
}

/**
 * Sets up the map if it is possible to do so (i.e., the Google Play services APK is correctly
 * installed) and the map has not already been instantiated.. This will ensure that we only ever
 * call {@link #setUpMap()} once when {@link #mMap} is not null.
 * <p>
 * If it isn't installed {@link SupportMapFragment} (and
 * {@link com.google.android.gms.maps.MapView MapView}) will show a prompt for the user to
 * install/update the Google Play services APK on their device.
 * <p>
 * A user can return to this FragmentActivity after following the prompt and correctly
 * installing/updating/enabling the Google Play services. Since the FragmentActivity may not have been
 * completely destroyed during this process (it is likely that it would only be stopped or
 * paused), {@link #onCreate(Bundle)} may not be called again so we should call this method in
 * {@link #onResume()} to guarantee that it will be called.
 */
private void setUpMapIfNeeded() {
    // Do a null check to confirm that we have not already instantiated the map.
    if (mMap == null) {
        // Try to obtain the map from the SupportMapFragment.
        mMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map))
                .getMap();
        // Check if we were successful in obtaining the map.
        if (mMap != null) {
            setUpMap();
        }
    }
}

/**
 * This is where we can add markers or lines, add listeners or move the camera. In this case, we
 * just add a marker near Africa.
 * <p>
 * This should only be called once and when we are sure that {@link #mMap} is not null.
 */
private void setUpMap() {
    mMap.addMarker(new MarkerOptions().position(new LatLng(0, 0)).title("Marker"));
}

And result:

As documentation sad

A GoogleMap can only be acquired using getMap() when the underlying maps system is loaded and the underlying view in the fragment exists. This class automatically initializes the maps system and the view; however you cannot be guaranteed when it will be ready because this depends on the availability of the Google Play services APK. If a GoogleMap is not available, getMap() will return null. SupportMapFragment
