Disabling and enabling internet in blackberry - blackberry

Question

I want to know what is the way to enable and disable internet connection in blackberry through coding.
EDIT
protected void disableConnection() {
activeConn = RadioInfo.getActiveWAFs();
if(activeConn == 0){
activeConn = RadioInfo.getEnabledWAFs();
}
mystore.setContents(new Integer(activeConn));
mystore.commit();
Radio.deactivateWAFs(activeConn);
Dialog.alert("Off internet");
}
protected void enableConnection() {
if(RadioInfo.getState() == RadioInfo.STATE_ON){
Dialog.alert("Internet on already");
}else if(mystore.getContents() != null){
if(Radio.activateWAFs(Integer.parseInt(mystore.getContents().toString())) == true){
Dialog.alert("On Internet");
}else{
Dialog.alert("Unable to on internet");
}
}else{
Dialog.alert("Unable to on internet");
}
}
These are two methods which I call on turn on and turn off button click.

Answer 1

You asked about internet connectivity, so I assume you are interested in more than just the Wi-Fi connection. Calling Radio.deactivateWAFs(RadioInfo.WAF_WLAN); will only disable Wi-Fi.
A better implementation would probably first check which radios are on, and then turn those radios off. When you want to turn service on again, reactivate the radios which you turned off. Something like this:
/** we record which radios are active */
private int _activeWAFs = 0;
private void getActiveWAFs() {
_activeWAFs = RadioInfo.getActiveWAFs();
if (_activeWAFs == 0) {
_activeWAFs = RadioInfo.getEnabledWAFs();
}
}
/** turn radios off if they're currently on */
private void disableAll() {
getActiveWAFs();
Radio.deactivateWAFs(_activeWAFs);
}
/** turn radios on, if we turned them off with disableAll() */
private void enableAll() {
boolean success = Radio.activateWAFs(_activeWAFs) && (RadioInfo.getState() == RadioInfo.STATE_ON);
if (!success) {
// do something?
}
}
Also, if you want notifications about the results of these operations, or external changes to the radio, you can implement RadioStatusListener:
public void networkStarted(int networkId, int service) {
if (RadioInfo.getState() == RadioInfo.STATE_ON) {
// network ready to use!
}
}
And, yes, this call will affect the entire device, not just internet connectivity for your app.

Answer 2

Radio.deactivateWAFS() will it deactivate all the wireless connection or just internet connectivity or Bluetooth connectivity.
Example: deactive WiFi connectivity.
Radio.deactivateWAFs(RadioInfo.WAF_WLAN);

Answer 3

try this -
this will turn on wifi-
Radio.activateWAFs(RadioInfo.WAF_WLAN);
this will turn off the wifi-
Radio.deactivateWAFs(RadioInfo.WAF_WLAN);
