I am trying to use ListView and extending ListActivity in main class. I am repeatedly getting the following RuntimeException and I am not able to figure out what differently I have done from other example apps that I have with me, that use ListView. So kindly help.

Basically the debugger sometimes takes you to "Looper.class", "Instrumentation.class" that are likely from the SDK. How to then ste out of those classes? In the case of the problem posted above, it did not even reach the first line inside oCreate(). Then how can we debug in such cases?

)? So please indicate which specific tutorial are you mentioning?You could use a service to communicate between two Activities.
Today I found a strange problem. I had a small program that worked fine standalone, worked fine as a simple Eclipse project, but throws Exception , when run within android Project (in IntentReceiver class or in main class within onCreate). The code simply contacts Google website and gets some data and processes it. The code has no programming or logical errors and is working fine in other two situations I have mentioned. Why would it fail within Android project? Any networking issue?
And what is the default duration till which Intents are valid or must be used within?
Finally which specific tutorial are u referring to when you mean "Advanced Tutorials"? And I wonder how I can get the reference to the SubActivity instance by running activities as services (Quote:
