Android cannot connect directly with a Postgres database, and cannot use JDBC connections

Question

I have this problem that my Android app cannot connect directly with a Postgres databse and cannot use JDBC connections. I've browsed the web a bit and some people say, that the best way to deal with this is to run a web service. I'm absolutely lost on how to tackle this problem. Should I build an extension of some sort or... ? Thanks in advance for the help.

Answer 1

It's possible to use JDBC with pgJDBC on newer Android versions, but not a good idea.

See JDBC vs Web Service for Android and Driver JDBC PostgreSQL with Android for why.

Basically, if you're on a device with potentially flakey connectivity, you don't want a persistent connection if you can use stateless HTTP requests instead.

Answer 2

You can never have a direct access to a database which is on a server. For this you need to run some server side code and use JSON to interact your app with server

And instead of connecting to MYSQL you can connect to PostgreSQL with the help of these docs:
