You have to enter the Google MAPS API key only then this code will work.
="1.0"="utf-8"
<com.google.android.maps.MapView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/mapView"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:clickable="true"
android:apiKey=API KEY"
/>
In place of API KEY, you have to enter the MAPS API KEY which is generated by google.
