Hi Fellows, I am new in mobile programming, I have been reading about classes on BB guide, I start doing my first App and I choose Phone classes, taking pieces of code from guide and try to run it on MDS simulator but I do not make it work.

here is piece of code I am using please advice what I am doing wrong.

package Blocker;
import net.rim.blackberry.api.phone.*;

public final class CallBlock extends AbstractPhoneListener
{
private Callblock(){}

public static void main(String argv[])
{
CallBlock.Startup();
}

static private void Startup()
{
CallBlock Tel= new CallBlock();
Phone.addPhoneListener(Tel);
}


public void checkCall(String ehandler, int callid)
{
PhoneCall pc = Phone.getCallId(callID);
String phoneNumber = pc.getDisplayPhoneNumber();
System.out.println(phoneNumber);
if (phoneNumber.equals("22670029"))
{
System.out.println("Blocked!!!!!");
}
}
}

to run an application you have to extend Application or UiApplication, depending on your needs to interfere with the UI.
you don't have to put everything into one class, just put up another class for your application.

Hi!

So you might want to sprinkle more System.out.println() statements through your code, to find out what's going wrong and where. This is sometimes known as "debugging by printf". Also make sure that the JDE's debugger is attached and active - System.out.println() only prints to a debugger window, not to the device's screen or event log. Look up the API for EventLogger if you want to make use of the device's event log facility to see log statements on a real device (real devices ignore System.out.println() but you can attach a JDE's debugger to a real device via a USB cable and the debugger will show those statements).

Be careful: Phone.addPhoneListener() will add another listener every time you execute your code - generally, you only want to do this once. Each listener will be executed - if you launch your application twice, two listeners get added and both will get executed when the Phone class runs through its list of listeners for each Phone event.

Cheers,

as long as one tests on the simulator it is therefor useful to mark the application or entry point as autostart

Thanks for your comment, as I said I just starting with this, is interesting what you said, but how I Configure it to start/autostart and be confident that will be run just once

Can you guys guide me how do this


thanks

if you use the JDE (at least partially): create a new project, set it to 'alternatce cldc entry point' and select your main application below. check 'autostart' and 'run as system module'. enter some string, like 'autostartup', as an argument for the main method.

in your main application check the parameter of main:
(a simple example)

public static void main(String[] args) {
         if (args.length > 0 && args[0].equals("autostartup")) {
                  Notificator.registerNotifications();
                   OptionsManager.registerOptionsProvider(new OptionsProviderImpl());
        } else {
                 X theApp = new X();
                 theApp.enterEventDispatcher();
         }
}

I have doing some tries how use phone listener but noone has been succesfully, does anyone have a sample code, it will very helpfull, I am just a student, please give me a hand.

thanks

Here is some sample application. I wrote it in the form editor -> there are no imports. Maybe there is some misspelling but it should compile. Put every code snippet into its according java file.

for simplicitys sake i will not use a proper callback routine but hand over the application itself.

//simple phonelistener application

public class MyPhoneListenerApplication extends UiApplication{

private MainScreen myPhoneListenerScreen;

public static void main(String[] args) {
MyPhoneListenerApplication theApp = new MyPhoneListenerApplication();
Phone.addPhoneListener(new MyPhoneListener(theApp));
theApp.enterEventDispatcher();
}

public MyPhoneListenerApplication(){
myPhoneListenerScreen = new MyPhoneListenerScreen();
pushScreen(myPhoneListenerScreen);

}

public void writeOnScreen(String text){
myPhoneListenerScreen.writeOnScreen(text);
}
}

public class MyPhoneListener extends AbstractPhoneListener {

private MyPhoneListenerApplication theApp;

public MyPhoneListener(MyPhoneListenerApplication theApp){
this.theApp=theApp;
}

public void callConnected(int callId) {
PhoneCall call = Phone.getCall(callId);
theApp.invokeLater(new Runnable(){
public void run(){
theApp.writeOnScreen("call from "+call.getDisplayPhoneNumber());
}});

}

}

public MyPhoneListenerScreen extends MainScreen{

private LabelField labelField;

public MyPhoneListenerScreen(){
setTitle("myPhoneListener");
labelField = new LabelField();
add(labelField);
}

public void writeOnScreen(String text){
labelField.setText(text);
}


}

Thanks for your Code, even it doesnt compile, it shows me some how use those classes and my code is working, now my problem is that this code should rund instead default phonelistener, but it doesn't.
the main idea it when a call arrives phone is compare to a list, if number is on the list, phone should not ring. any idea

thanks for all your patience and support.
