I am new here, and I notice that the official book site lists only two errata; however, these forums seem to identify many more undocumented problems and their solutions. Should readers be required to dig through the forums to find out about errors in the book? If so, is there a way to tag posts as containing errata?

I agree with the person (DrGiribaldi) who commented tagging posts that contain errata.

I also have a problem: running the Earthquake app on emulators that consist of a build from Android 2.0+ source code. It seems that the Google MAPs API has been removed from the Android source code. In the console you get an error Chapter 10 Earthquake 3 Installation error: INSTALL_FAILED_MISSING_SHARED_LIBRARY

A partial work around is to make the following change in AndroidManifest.xml and add android:required="false" as follows:

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

So then the app will load and display earthquake info, but if you click/press the menu button you get Force close error as follows:

"Sorry! The application Earthquake (process com.paad.earthquake) has stopped unexpectedly. Please try again. Force close"

The app runs just fine in Google API AVDs and on my phone, but not in emulator that consists of compiled Android source code and kernel. Why? What can I do to fix it?

Unrealated to the Errata's listed above, but there seems to be erratas on page 235 and 238 referening which sample projects are available to download. It is referencing the ToDoList project, but should be the earthquake one.
