Question

I want to import these packages
import com.google.android.maps.MapActivity;
import com.google.android.maps.MapController;
import com.google.android.maps.MapView;
in my mainactivity.java

But Eclipse cannot resolve these packages , and i don’t know the reason for this.

I’ve followed all the instructions i found on an e-book , step by step,on how to import maps in your app, and there is nothing mentioned about this error.

Here’s my files:

Right click on your projects —> properties —> android –> select target name Google ApIs. And Clean projects and Build the projects.
