Question

Can I get the number that is calling by native dialer ?

I want to show the "toast message" with information about cost per minute according to a dialing number. But I do not know how to get this number.

It could be good to have sample which show "toast message" with dialed number during of call.

yes you can do it.You need to implement PhoneStateListener

public class CustomPhoneStateListener extends PhoneStateListener {

public static Boolean phoneRinging = false;

public void onCallStateChanged(int state, String incomingNumber) {

    switch (state) {
    case TelephonyManager.CALL_STATE_IDLE:
        Log.d("DEBUG", "IDLE");
        phoneRinging = false;
        break;
    case TelephonyManager.CALL_STATE_OFFHOOK:
        Log.d("DEBUG", "OFFHOOK");
        phoneRinging = false;
        break;
    case TelephonyManager.CALL_STATE_RINGING:
        Log.d("DEBUG", "RINGING");
        phoneRinging = true;

        break;
    }
}

}

To register the listener do this:

        CustomPhoneStateListener phoneListener = new CustomPhoneStateListener();
        telephony = (TelephonyManager) context
                .getSystemService(Context.TELEPHONY_SERVICE);
        telephony.listen(phoneListener, PhoneStateListener.LISTEN_CALL_STATE);

Note that access to some telephony information is permission-protected. Your application won't receive updates for protected information unless it has the appropriate permissions declared in its manifest file. Where permissions apply, they are noted in the appropriate LISTEN_ flags.
