No I'm testing on a Nexus...
Ok.
But I can't be responsible for user's individual settings, so I'll
just have to assume that in some cases the network will not be
available during the night. Unless there's a command to explicitly
wake up the connection?
Well, some devices have really weird settings, like the HTC "fast boot"
optimization for the Desire HD, which disables BOOT_COMPLETED. So at
least you can be aware of it. But since your phone is not an HTC....
There is this:
http://developer.android.com/reference/android/net/ConnectivityManager.html#setNetworkPreference(int)
but i haven't had much experience with it, since my phone keeps the
mobile connection on at all times, as seen in the log entry I posted before.
What happens if you just go ahead and start your network operation?
Might cause the phone establish a connection just then, on demand. If
not, I suppose your code catches IOException already, right?

Interesting.
I take it by wireless you mean cellular?
My HTC Hero has an option for "always on cellular data connection" - I
guess it's specific to HTC phones, as neither my Samsung Galaxy S or
Motorola Milestone have that.
Is your phone made by HTC by any chance? If so, perhaps you could check
that setting.

Yes, looking at the log output, it seems the device disables the
wireless connection after a few minutes while the phone's sleeping, to
save resources I suppose. So I'll just have to code around that, and
reset the alarm to try again until the connection is back.

Neil,
That's pretty much how I test too, except my code lacks a check for
isConnected, only for null.
This is what I get in my app's log:
NetworkInfo: type: MOBILE[EDGE], state: CONNECTED/CONNECTED, reason:
apnSwitched, extra: internet.mts.ru, roaming: false, failover: false,
isAvailable: true
Two ideas:
- Check your phone settings, perhaps yours has some kind of sleep policy
for mobile data;
- Log the value you get by calling getActiveNetworkInfo into a file, and
examine later.

Hi Kostya.
Yes, the alarm gets called... it's just my own call which stops it
doing it's task. For example:
if(isNetworkAvailable(mContext)){
// do stuff...
}
public static boolean isNetworkAvailable(Context context) {
ConnectivityManager connMgr = (ConnectivityManager)
context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo info = connMgr.getActiveNetworkInfo();
return(info != null&& info.isConnected());
}
So this call tells me the network isn't available when the phone's
asleep. I guess I'll have to try another way of testing for the
network?

Ok, one problem with this alarm service.
I schedule it for some time in the morning, and when I get up and
check the phone, the alarm didn't get called, because it thinks
there's no network connection.
I'm sure the alarm did get called, as the AlarmManager service has
nothing to do with networking.
This is a call I make deliberately (I always check there's a
connection before making the server request)... but why does it think
there's no network when the phone is 'sleeping'? The connection is
still there...
Depends on what kind of network connectivity you expect.
In my tests (Moto Milestone), WiFi doesn't get enabled when the phone is
woken by an alarm, but the cellular data connection is available
immediately.
