    The accepted answer by Priyank is right. I just wanted to point out some corrections in the code in the Intent class

    @Override
    public void onReceive(Context context, final Intent intent) {
        if (intent.getAction().equals(Intent.ACTION_NEW_OUTGOING_CALL)){
            String phoneNumber = intent.getExtras().getString(Intent.EXTRA_PHONE_NUMBER);
    
            if(phoneNumber.equals("#1234#")){
                Intent intent1 = new Intent(context, YourActivity.class);
                intent1.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                context.startActivity(intent1);
            }
    
        }
    }

    You can start your application activity class by dialer but for that your app should running in background. for that you should implement a class which extends to BroadcastReceiver. follow this reference code.

    public class Example extends BroadcastReceiver 
    {
    
        @Override
        public void onReceive(Context context, final Intent intent) {
    
          if (intent.getAction().equals(android.intent.action.NEW_OUTGOING_CALL)) {
           String phoneNumber = intent.getExtras().getString( android.intent.extra.PHONE_NUMBER );
    
             if(phoneNumber.equals("#1234#")) { 
                Intent intent1 = new Intent(context , YourActivity.class);
                intent1.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK );
                context.startActivity(intent1);
           }
    
          }
    
        }
    
    }
