yes you can .... extend BroadcastReceiver and override onReceive as the following

public class CallListener extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {

        if (intent.getAction().equals(Intent.ACTION_NEW_OUTGOING_CALL)) {
            String phoneNumber = intent.getExtras().getString(Intent.EXTRA_PHONE_NUMBER);
            System.out.println(phoneNumber);

            if (phoneNumber != null&& CallService.phoneNumber.equals("ANY_NUMBER_YOU_WANNA_INTERCEPT_ON")) {

                //do what you want to do :)
            }
        }

    }

and you will need to add your BroadcastReceiver on the AndroidManifest.xml as the following

<receiver android:name=".CallListener" android:permission="android.permission.PROCESS_OUTGOING_CALLS">
        <intent-filter>
            <action android:name="android.intent.action.NEW_OUTGOING_CALL" />
        </intent-filter>
 </receiver>

You can use PhoneStateListener with a custom broadcast receiver, which gets you onCallStateChanged(int state, String incomingNumber).

(You'll also need <uses-permission android:name="android.permission.READ_PHONE_STATE" /> in your AndroidManifest.)

Thanks Ben Williams, I want to get the number when a user make a call. the number where a call is made too. – shebelaw May 04 '11 at 14:49
I'm not sure you can directly, but if you're listening for phone state changes, you should be able to tell when a call went out and ended, and then immediately `CallLog.Calls` and `getLastOutgoingCall` gives you the last called number. – Ben Williams May 04 '11 at 14:59
tanks again. I will take a look in to that. But what I really want is to get the number while the call is active or when the call button is tabbed. – shebelaw May 04 '11 at 16:54
