Here are a few changes I made to the ReadMessages class but it still takes like 30-45 seconds for the a new message notification.
Service.getInstance().S.CNMI_EMULATOR_INTERVAL = 2; Service.getInstance().S.WATCHDOG_INTERVAL = 3;
I minimised the period to which the application checks if there is any new message and set it to 2.
Any changes to the code or advise will be appreciated.
Below is the ReadMessages class.
