what is whrong in this code snipet?

public void registerOnStartup() {
        Incomins_Call_Block phone_handler = new Incomins_Call_Block();
        Phone.addPhoneListener(phone_handler);        
    }
    public void deRegisterOnEnd() {
        Phone.removePhoneListener(phone_handler);
    }

i get the following error when i compile the code for text in red
"cannot find symbol"

Incomins_Call_Block phone_handler = new Incomins_Call_Block();
public void registerOnStartup() {
       
        Phone.addPhoneListener(phone_handler);        
    }
    public void deRegisterOnEnd() {
        Phone.removePhoneListener(phone_handler);
    }

and for this snipet i get a exception"net.rim.vm.StackOverflowError"

i tried doing it this also :

public void registerOnStartup(int i) {
      
       Incomins_Call_Block phone_handler = new Incomins_Call_Block();
        if(i == 1) {
            Phone.addPhoneListener(phone_handler);
        }
        else {
          //  Dialog.alert(" bye bye "); 
            Phone.removePhoneListener(phone_handler);
            phone_handler = null;
             System.exit(0);
        }
    }

but when i pass i=0....the listener does noyget removed.
can someone help.

thanks

I didn't work with Phone and PhoneListener and don't know why StackOverflowError happens. Maybe problem is inside Incomins_Call_Block implementation itself.

But in 1st code snippet error happens because you define variable in one method and use it in another method. In 3rd code snippet you create new Incomins_Call_Block object on every registerOnStartup() request and objects, passed to addPhoneListener() and removePhoneListener() are different objects

I realised my mistake....and the solution would b to send the app in the background when activated .but i am new to BB programming and have yet not figured out how to do so.I know the Application call api will be usefull but have not been able to figure out use it.

Could u help me

You can call Application.getApplication().requestBackground() to send application to background.
But frankly speaking, I don't see how it will solve StackOverflowError problem...
