When I tried to run the sample code for Chapters 7 & 8 in the Emulator, I got the errors from logcat:

E/PackageManager( 569): Package com.paad.earthquake requires unavailable shared library com.google.android.maps; ignoring!
W/PackageManager( 569): Package couldn't be installed in /data/app/com.paad.earthquake.apk

Does this mean we cannot run these samples in Emulator?

By the way, PAAD is great book, recommended for everyones like to study Android Programming!

In the properties of your project, click Android: the project build target should be Google APIs
Then map.jar gets included like android jar

Also, when using the emulator for maps related programming choose Google APIs as the target

Seems like strange naming at first. (Soon there will be all kind of external libraries?)
But otherwise I'am also having fun trying out Android programming with this book
