Accessing node.js server on my local system using android app

Question

I have a node.js server running on my local system which interacts with postgresql in the same system to fetch and save data. I want to access node.js server from my android app to save and fetch data from postresql. The problem is my app is not able to connect to localhost. As localhost for my phone is different from my local system and if I am providing my system's IP address then also its refusing the connection.

Answer 1

I made server listen to hostname '0.0.0.0'. Initially I was not providing any hostname as argument in server.listen i.e it was like server.listen('portnumber') which I changed to server.listen('portnumber', '0.0.0.0');
