App getting close on connection (without error log)

[shashankjamdade]

I have set the nodejs backend at my local machine and run the test android app with given code by putting my localIp address (common n/w ip). Its working fine as if I tried to call unregistered user it shows the toast for user unregister etc. when I tried with register user and tried to connect them android app get close automatically without showing log in android studio. I am unable to figure out the problem, please help me.
