What tutorial in Youtube you are talking about?

Please note that an Android app isn´t a Onlineapplication.
For that the app needs to run 24/7. Android apps are not expected to do so.

B4J Server app are.

As @Brian Dean already told: without seeing what code you use it is hard to give any congrete answer. Best is to export your project as zip and upload it.
