Inflate Error on Google Maps v2

Question

I try to add a Google Map to my application and using this tutorial I generated API code, added all necessary meta data, permissions etc. Whenever i click the button to start a new activity the app crashes on my Galaxy S3

onClickListener

Button.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                if (v == Button) {
                    startActivity(new Intent(MainActivity.this, ShowMap.class));
                }
            }
        });

Map class

public class ShowMap extends Activity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.show_map);

    }
}

show_map.xml

<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
          android:id="@+id/map"
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          android:name="com.google.android.gms.maps.MapFragment"/>

The class com.google.android.gms.maps.MapFragment is not found. Check if library google-play-services_lib is properly linked to the project.

Oh, I got it. It says "Copy the /extras/google/google_play_services/libproject/google-play-services_lib library project into the source tree where you maintain your Android app projects." But my extras folder does not have a folder as google. I have already downloaded Google Play Services SDK – Onur Mar 15 '13 at 17:59

Check this http://stackoverflow.com/questions/14371725/add-google-play-services-to-eclipse-project question. This can help you with adding the project to workspace. – andrew Mar 15 '13 at 18:19
I added it to project. They are in the same workspace and i also made library things in my project's properties, but it still gives an error. Error stack is renewed – Onur Mar 15 '13 at 18:26

your ShowMap should extends FragmentActivity for this to work not Activity , check the examples included in google-play-sevice library for google maps they are a big help.

Edit

make sure you are including google-play-service library project, as the exception is ClassNotFoundException: com.google.android.gms.maps.MapFragment

check this link on how to include the library project

@Onur maybe you need to redownload it, check if you have the latest google-play-services – Moh Sakkijha Mar 15 '13 at 17:59
Found it, added to project using properties>android>library but it still gives an error. I replaced the error stack – Onur Mar 15 '13 at 18:17
@Onur try using SupportMapFragment not MapFragment in your xml – Moh Sakkijha Mar 15 '13 at 18:36

I use the API key which has been given first and it worked. I don't know why, but currently there is a different id, which causes "Authorization error" – Onur Mar 19 '13 at 16:21
