When I try to run this, my preferences activity does not start. This happens whether I run my own app or the one downloaded from Wrox.

I noticed that when I create a new Android Application Project, I have a file <project>/res/menu/main.xml and my main activity has a skeleton onCreateOptionsMenu() function. If I don't delete these - the 'menu' folder and the function skeleton - my projects will not build. Do I need to insert something into this Earthquake Part 1 project to replace what I deleted?

Hi oddstray,

The earthquake part 1 code in ch 7 does not make use of any xml file in res/menu, as there isn't such. So i don't understand what you want to do with /menu/main.xml? Build without that should go without errors, what errors do you see?
After clicking menu and then "Preferences" an intent is sent to start preferencesActivity that will show res/layout/preferences.

Good luck!

I do not see any errors.

What I do with /menu/main.xml is to delete it because it is not used or needed, before I build (my projects will never build unless I delete /menu/main.xml and the onCreateOptionsMenu() override in the main activity class).

When I run the my code for the first part of Chapter 7, or when I run the downloaded book code for the first part of Chapter 7, after clicking the menu and then "Preferences", the res/layout/preferences is not shown. Nothing happens (and there are no additional messages in my Console or in LogCat).

This is very odd, oddstray

I just loaded the code on eclipse and found no problems, the only way that PreferencesActivity does not show up is when i don't have
implemented. Be sure that here the intent is really sent.

Hmmm ... first, when I thought I was running the book code, my Eclipse insisted on running my code. So, it didn't work.

Tonight when I started Eclipse I ran the book code first thing. Then it ran correctly.

And d'oh! What I found was the "onOptionsItemSelected" != "onOptionsItemSelection"


Thanks for helping!
