TelephonyManager telMng = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);    
telMng.listen(new PhoneStateListener() {    
    @Override
    public void onServiceStateChanged (ServiceState serviceState) {
        super.onServiceStateChanged(serviceState);
        String phonestate;

        switch(serviceState.getState()) {
            case ServiceState.STATE_EMERGENCY_ONLY: 
                phonestate ="STATE_EMERGENCY_ONLY";
                break;
            case ServiceState.STATE_IN_SERVICE: 
                phonestate ="STATE_IN_SERVICE";
                break;
            case ServiceState.STATE_OUT_OF_SERVICE: 
                phonestate ="STATE_OUT_OF_SERVICE"; 
                break;
            case ServiceState.STATE_POWER_OFF: 
                phonestate ="STATE_POWER_OFF"; 
                break;
            default:
                phonestate = "Unknown";
                break;
        }   
    } 
}, PhoneStateListener.LISTEN_SERVICE_STATE);
