Google Map Android Api V2 Sample Code not working

Question

I had tried to use the Google Map Sample Code before which was provided in Google_Play_SERVICE/SAMPLE by using all the available options and it showed the below Log.

01-14 17:58:39.773: E/Google Maps Android API(13114): Authorization failure.

It showed me the blank screen for all of the sample Map options.

Now I created a new Project and here is its complete code:-

Activity.java

public class MapActivity extends FragmentActivity
{
    private Context context = this;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_map);

        GoogleMap gMap = ((SupportMapFragment)getSupportFragmentManager().findFragmentById(R.id.map)).getMap();

        int result = GooglePlayServicesUtil.isGooglePlayServicesAvailable(context);
        Log.e("Maps", "Result int value::" + result);
        switch (result) {
        case ConnectionResult.SUCCESS:
            Log.e("Maps", "RESULT:: SUCCESS");          
            break;

        case ConnectionResult.DEVELOPER_ERROR:
            Log.e("Maps", "RESULT:: DE");           
            break;

        case ConnectionResult.INTERNAL_ERROR:
            Log.e("Maps", "RESULT:: IE");           
            break;

        case ConnectionResult.INVALID_ACCOUNT:
            Log.e("Maps", "RESULT:: IA");           
            break;

        case ConnectionResult.NETWORK_ERROR:
            Log.e("Maps", "RESULT:: NE");           
            break;

        case ConnectionResult.RESOLUTION_REQUIRED:
            Log.e("Maps", "RESULT:: RR");           
            break;

        case ConnectionResult.SERVICE_DISABLED:
            Log.e("Maps", "RESULT:: SD");           
            break;

        case ConnectionResult.SERVICE_INVALID:
            Log.e("Maps", "RESULT:: SI");           
            break;

        case ConnectionResult.SERVICE_MISSING:
            Log.e("Maps", "RESULT:: SM");           
            break;
        case ConnectionResult.SERVICE_VERSION_UPDATE_REQUIRED:
            Log.e("Maps", "RESULT:: SVUR");         
            break;
        case ConnectionResult.SIGN_IN_REQUIRED:
            Log.e("Maps", "RESULT:: SIR");          
            break;      

        default:
            break;
        }
        gMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
        gMap.setMyLocationEnabled(true);
        Log.e("Maps", "------EOC-------");
    }
}

Screenshot

This is the result, Blank screen with zoom options, No map in MapView.

I have followed each and every step mentioned at:-

1.) Tutorial

2.) Google Map Android Api V2

Answer 1

Please check..

1. check if the "libs" folder containing the "android-support-v4.jar" exists in your project.

   "android-support-v4.jar" is located in "/extras/android/compatibility/v4/android-support-v4.jar" under your "android-sdk" drectory.

2. Before running your project, you must set your project Build target to "Google APIs", not Android x.x. version : Select your project and click Project > Properties > Project Build Target in Eclipse and select any "Google APIs ", and then run your project on your phone. If you use the emulator, also MUST set the AVD of the emulator to the any "Google APIs ".

3. Once more, you don't need to create the new Google Maps API key in order to test your project, Just use the default provided API key, which is shown as "Key for browser apps (with referers) "in your Google APIs Console.

4. Finally, the most important is to add Google Play services as an Android library project as follows:

   Select File > Import > Android > Existing Android Code Into Workspace and click Next. Select Browse..., enter /extras/google/google_play_services/libproject/google-play-services_lib, and click Finish.

Answer 2

Got this problem because I had restriction enabled for my API key in Google Console.

Make sure it is set to none and then try again
