google map - runtimeexception - error inflating cl

问题:

I just try to view a map on the display, but it does not work. I get an runtimeexception:

01-17 19:16:47.066: E/AndroidRuntime(6605): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.maptest/com.example.maptest.MainActivity}: android.view.InflateException: Binary XML file line #7: Error inflating class fragment

import com.google.android.maps.MapView;
import android.os.Bundle;
import android.app.Activity;

import android.support.v4.app.Fragment;




public class MainActivity extends FragmentActivity {
 getSupportFragmentManager().findFragmentById(R.id.map))

@Override
protected void onCreate(Bundle savedInstanceState) {
    GooglePlayServicesUtil.isGooglePlayServicesAvailable(getApplicationContext());

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);


    SupportMapFragment fragment = new SupportMapFragment();
    getSupportFragmentManager().beginTransaction()
            .add(android.R.id.content, fragment).commit();

    setContentView(R.layout.activity_main);

    GooglePlayServicesUtil.isGooglePlayServicesAvailable(getApplicationContext());

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


}

The key is v2 and i followed strict the google tutorial i found. I also imported android play services.

Could someone help me please? :)

I had a similar error when trying the Map API v2. However, I don't know whether it will help you.

My problem was that the google-play-services_lib had to be included as a library. In Eclipse, you can do this as follows:

1. Use the Android SDK Manager to download the library.
2. Create a new "Android Project from existing code" where you point to google-play-services_lib in the folder you used to install the SDK.
3. Under "Project -> Properties -> Android" flag this project as "Is library".
4. In your project, also open "Project -> Properties -> Android" and click on "Add" in the library section. Select the google-play-services_lib.

At least that worked for me.
