Android Question Do we need a PC for RDC (Remote Database Connector) to work properly on Android or iOS?

[jkhazraji]

Concerning this tutorial, it was mentioned that we need 2 servers to connect to the database , one is the database server and the other is the jServer which uses the jRDC2 implementation. Well, does that mean we need a PC to start the jServer every time we want to connect our Android (B4A) or iOS (B4i) app to the remote database. It is a bit impractical or am I mistaken? It will make the app running on the phone dependent on another device which is the PC or whatever setting to start the jServer. Thanks

You can run jRDC2 on the same computer that runs the database server. It can be Linux, Mac, PC, Raspberry Pi or any other computer that supports Java.

What if the database was hosted on a remote computer as a part of website hosting plan and I want to fetch data from that database by jRDC2 ?

Shared hosting will not work. You need a VPS to run jRDC2.

There are exceptions.
I am using a Hosting Provider where i can configure the MySQL-Database(s) to be accessible from outside. This can used to directly access the Database using jdbcsql (which is not recommended). If you need to use jrdc2 you need to have a PC/VPS running.

But i agree: Most providers does not support it so a VPS is the solution here.

This is not enough if you want to run jRDC2 on your server directly.

Sorry, my comment was meant regarding mysql-access only (and the use of jdbcsql then).
I edited my post above...

typically u can use php or asp.net at server side to provide data by http request. Lib OkHttpUtils2 can do this requests for download & upload.
jRDC2 is much better to access Data and a VPS is more expensive than web hosting.
