Android introduced a CalendarView back in in API 11. I've implemented it in
my app and it seems to work fine in the sense that it displays a perfectly
normal-looking whole-month calendar and I can select a date and it triggers
the appropriate event and I can read the selected date in my code

I just installed Android Studio 1.01 and I'm getting up to speed on it. In
my "Hello Android" app I deliberately introduced a compiler error to see
how that's handled.
The development environments I've used (Visual Studio, Eclipse) have a
window which displays errors and warnings after a build,

Just that - what tools or strategies are recommended to see what code is
executing in which threads - how do experienced Android programmers debug
these kinds of exceptions?

I have a multi-threaded Android app. One thread wakes up periodically on a

other one is the main thread that handles all the usual View stuff.

I fixed the *getCount()* problem. After updating the listItems I now call
*setListAdapter()* on the ListActivity. (@Streets of Boston - there is
only one ListActivity). After that, when I call the ListView's

7;s how the original program was
architected and I don't have the authority to change the architecture.
But why does it matter?Why can't the size of a ListView be reset if
it's static?

There's a lot of proprietary code in the adapter; I'll see if I can whittle
it down to something simple but meanwhile I'd like to pursue the listview's
strange getCount result. Because that's a separate question from the
getView()'s position value (maybe) I've started a separate thread focus
I have a listView in an android app which works fine when I first populate
it - it displays and scrolls with no problem. But if I load in a new,
smaller dataset and call notifyDataSetChanged() the app crashes because
getView() gets called with a position value that's bigger than the dataset,

Sorry - should be lv.get*Count*.
And yes, I am calling notifyDataSetChanged.
I've also tried calling the ListView's *invalidate()* method, with no
change in the behavior.
Since posting this I've written a whole separate version of the program
where I initially display 12 items ( listItems
I'm getting a crash in my adapter's *getView()* routine because it's being
called with a position value of 6 and my datasource only has 6 items in it.
So I assumed that the position parameter should be in a range of [0]-[5]?

Just an update: to simplify things further I replaced the layout file with

As I explained in the OP, the Android devices are used in an industrial
environment. Specifically they are used in a factory where they are
sending and receiving information to a central process
Just an addendum - I tried setting the WiFi Sleep Policy to "Never" in the
WiFi Settings advanced Menu and it made no difference - unless I let the
screen stay on, however dimly, as soon as the display goes out it sends a
"fin" to the server.
