 Re your question about implementing a service that polls for updates, please
look at some of the sample code. For example, Romain Guy's Photostream demo
application has a background service that polls the Flikr API webservice for
updates and displays a notification in the notification bar. AFAIK whether
the access is by phone network or WiFi is functionally irrelevant.

 Is the service completely crashing due to the exception or does the service
continue to get the exception subsequently? Are you perhaps wrongly assuming
that the phone is connected to the internet whenever you want it to be?

Network Unreachable ( Exception)

by Frank Weiss » Mon, 08 Feb 2010 10:50:10 GMT

 The network unreachable error is always a networking problem. Could be the
local network interfaces (wifi and phone) are turned off or temporarily
disabled, a bad network mask setting, or some router is unable to route an
IP address. It may also be an ipv6 config error. It may be occuring while
trying to resolve DNS (DNS server is unreachable). I have some suggestions:

1) Describe the network environment: emulator or device (which device) WiFi
on or off, wireless network carrier, local network configuration, including
firewalls (if using emulator or WiFi).
2) Test the application in a different network environment (home, office,
friend's house, cafe).
3) Add code that when the exception occurs, tries to access the network by
some other means besides HttpUrlConnection.
4) As 3), but try using a different Android application that accesses the
5) Try using an IP address instead of hostname.
6) I forgot to add, once the error occurs, how do you get the service to
connect again?

2. How to detect if the soft keypad is up or down

Hi All,

I would appreciate if anyone has a means to detect if the virtual
keyboard or the soft keypad is up or not.
I used inputMethodManager's isActive() routine but it's always
returning TRUE indicating it's not the right API to use.

I have to do certain user-input dependent tasks based on whether the
keyboard is up or not. Hence the need to detect the state of the soft
