Privet Rustam,
Cellular data connections are managed automatically. Some phones (HTC)
have a setting for keeping a data connection at all times. Others
establish the data connection on demand.
WiFi connections are established whenever a configured ("known") network
is within range.
So in your service, you can just connect and it should just work.
The only exception is when your service wakes up the phone from sleep,
and WiFi is enabled by the user. If there is a network within range,
Android will connect, but it might take a few seconds, because WiFi
radio is usually disabled when the phone sleeps.
If you wanted to make your service really smooth (and save users some
money), you could detect this, and delay your network operations until
the WiFi subsystem is done connecting (you can monitor broadcast actions
from ConnectivityManager or WifiManager for this). A few seconds should
be enough. Remember to acquire a wake lock, so the device doesn't fall
asleep while you're waiting for a connection.

Hi thanks, will check that
regarding the first question, just want to make it absolutely clear
lets consider following situation:
on my Android cell I have 3g connection available(not connected, there
is difference), if my App Service(background) needs Internet
connection would it or would it not ask user's permission to connect
to network?

Rustam,
To stop all the data connections while working on emulator,
you need to configure it through DDMS perspective.
Open it and go to "Telephony Section",
There you will find a drop down for the "Data" services,
choose appropriate option for your requirement from "home", "roaming"
and "denied".
I dint get what you want to ask in the first query.
If there is any open or public network available to your phone, it
will connect to it automatically,
provided you have not activated "airplane" mode.
First you need to connect your phone to any working network,
then only your app can also make any remote connection.
