The actual hierarchy is:

AndroidLove -> src -> android.love -> HaikuDisplay.java

Should say onLoveButtonClicked instead of onLoveVuttonClicked.

Using R12 SDK/emulator against Android 2.2, no IOException is generated. The only thing returned is a vague "permission denied".
Of course this never gets printed to the log because of the try...catch in IotdHandler which silently ignores the exception and continues as if nothing happened.
It wasn't until I changed the code into
URL dataUri = new URL(url);
InputStream inputStream = dataUri.openStream();
reader.parse(new InputSource(inputStream));
} catch (Exception e) {
String error = e.getMessage();
System.out.println(e.getMessage());
}

and ran it through the debugger that at least that much was visible.
A watch on the exception shows it to be a java.net.SocketException with no further information.

then add it to the app’s current layout.

In both of these pages and anywhere else in this chapter that the magnets are used with the "layout_xxx" attribute, the magnet incorrectly uses a dash instead of an underscore. This is true for some of the values as well (i.e. wrap-content instead of wrap_content).

Capitalize the third sentence starting with "you"

You should have also dismissed when dialog once the work is
completed.

Change "when" to "the".
I'm guessing "once the work is completed" should be in the past tense.

thread has a queue of work, and it continually gets the mot important
chunk of work to process."
It should say "more" instead of "mot".

It should say "Repaint" instead of "Repain" in reference number 2.

The second task has a label of "Pperform layout". Should it be "Perform layout"?

Task 1 reads "This expensive call on call

"call on" is repeated twice.

On Task 2 change "Repain" to "Repaint"

"ExitText" should be "EditText"

RESULT_CANCELLED should be RESULT_CANCELED

The request code passed into
startActivityForResult is returned along with
the request code set before finish was called.

I think that it should be:
"The request code passed into
startActivityForResult is returned along with
the result code.... "

The last sentence of the first paragraph states "Then using a database API, your app would connect to the database and query or addsdata to the database."

This looks like it should be "add data" not "addsdata".
