At any rate, here is the log I am getting when I try to run it on my device. My device, BTW, is a Nexus One with Android 2.1 update1 running on it.

...
@w_darryl, you should include the part of the log where it has ERROR messages.
I think these warnings are not the cause of the Force Quit.

Hi Reto,

Thanks for your post on April 7th regarding Line 191 of the EarthquakeProvider class (introduced on Page 232) has a superfluous ")". That helped me get Chapter 10 Earthquake 3 running.

But in the Earthquake menu when I select "Earthquake Map" I get a white screen with red dots on it. I don't get a nice map as shown on http://blog.radioactiveyak.com/2010/...arthquake.html

Is this a known problem? I have been googling for a solution but can't find one.

Vince

Hi Reto,

In logcat I got this message when trying to view an Earthquake Map:
"failed to find provider infor com.google.settings"

I googled the logcat message and learned about Android Maps API Key Signup.

After reading your book a bit more my Earthquake Map problem is solved in section "Getting Your Maps API key"

Now I get a nice earthquake map on the emulator and Nexus One.

Thanks! Great book!

Vince

Dude as of March 2011 this is still not fixed in the code?

Edit: Well the bug was still in Chapter 7 Earthquake 2

There's a typo that somehow managed to sneak through in both the code and the examples.

Line 191 of the EarthquakeProvider class (introduced on Page 232) has a superfluous ")". It should read:

Code:
+ KEY_MAGNITUDE + " FLOAT, "
NOT

Code:
+ KEY_MAGNITUDE + " FLOAT), "
I'll update the downloadable code samples ASAP and add this to the book's errata page. Thanks for letting me know!
Whew..thanks for this..the widget example was driving me nuts....works beautifully now...

I point out that I have generated my maps key, there are some problems with the usability of the app, e.g. I see the red dots on the map but I cannot zoom the map, or when I switch between activities I can only use the esc tab to do so, is that normal?

Default Chapter 9 Earthquake example code problem
Hi,
I download code example from wrox site and import Chapter 9 Earthquake (2, 3, 4 all same result) and do

1. set Build target to Google APIs (Android 2.1)
2. change EarthquakeProvider.java
" + KEY_MAGNITUDE + " FLOAT), "
to
" + KEY_MAGNITUDE + " FLOAT, "
3. run -> Debug
4. result is Earthquake not response and force close.
5. logcat error show
Code:

After modify "+ KEY_MAGNITUDE + " FLOAT), " to + "KEY_MAGNITUDE + " FLOAT, " Chapter 8 program running OK but Chapter 9 (all version, chapter 10 etc.) still have problem.

Could you check and update?

By the way code example for Android 4 book is OK. But for Android 2 I can not get it run.
Thank you,
