Hi,
I am new to developing in the Android OS. I am executing the sample code (unmodified) from chapter two which shows how to use intents. when I hit the choose contact button I get my list of contacts, then select a contact from the list. The problem is: No contact information is displayed on the emulator screen, and the code seems to stop running in the "ActivityThread.deliverResults" method. However the emulator cannot find the source code to display.

Can someone please offer a suggestion: 1. why is the code stopping without an error message, 2. Where should the source be located? I have looked through the Android SDK directories for this class & method and can't find it.

Thanks very much - frustrated

Hi dac77
Well unless you have entered some contacts in the list it will be empty.
Tap on the contacts icon in the emulator and add a few contacts. then your program will respond as it should.
Second part.
Did you hit the 'back button'? It will wait for you do something.
Where should what source be located?

Cliff,
First, thanks for the reply, you are the only one to respond.

I have added contacts to the contact list and I am able to select from
the list, so that's not a problem. The problem is after the selection is made
the code stops executing with a runtime exception (I included the call stack below). In the source code window of eclipse I get a message that says
"Source not found." The classname in the tab of the source window is the
same as the last entry in the call stack "ActivityThread.deliverResults".

So I don't know why it is getting the exception, and I'm not sure where to
look for the source code so I could add its directory to the source path.
As I mentioned this is the unmodified code, right from the example.

Any suggestions are appreciated.

Thanks much
Dave

Hi Dave
My guess is that it can't find the activity to go back to(?). Check you manifest file and see that the intent filters are good. Also check where you create the intent and make sure that you handle the return data correctly. That is, check the onActivityResult code is good.
