How to use maps on physical android device?

Issue

I need to use maps on running in a physical Android device, how do i do that?

I do not want to use the AVD for debugging it.

By the way i get the same error on AVD so please help? here is my code

<com.google.android.maps.MapView
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/map"
        android:apiKey="0enZtoViiB7JtEUxmyjwYWuw0Hz8pdTqNNWtBjQ"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:clickable="true" />

AndroidManifest.xml

<uses-library android:name="com.google.android.maps" />

Activity:

public class AroundMeActivity extends MapActivity {

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.qa_layout_activity);

    MapView mapView = (MapView) findViewById(R.id.map);
    mapView.setBuiltInZoomControls(true);
}

@Override
protected boolean isRouteDisplayed() {
    return false;
}
}

Solution

This Exception usually means that you have symbols collision in your project. Make sure that you included maps.jar only once in the project.
