Android Telephone manager to detect sim

Question

I am working on an Android auto-start app that\'s basically dependent on SIM card state. When my app auto starts I need it to check where the SIM card has been changed or n

Answer 1

If you want to react to a Sim change you need to set a listener:

final TelephonyManager tm = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);

    tm.listen(new PhoneStateListener() {
        @Override
        public void onServiceStateChanged(ServiceState serviceState) {
            //Code in here executed on Sim State change
        }

        @Override
        public void onDataConnectionStateChanged(int state) {

        }
