How can I upload data for a example a magazine and retrieve it on my app running on my phone

I have an app for the sale of Magazines, how can I upload these magazines so that anybody using the app can download the magazine.

Are the magazines represented as objects in your app or as files?

as files

Then you need to use File upload API.

Is the app in iOS, Android or JS?
Did you create an app in 3.x or 4.0 version of Backendless?

Android App

Did you create an app in 3.x or 4.0 version of Backendless? Yes I did

Frank, this was an “OR” type of question:

Did you create an app in 3.x or 4.0 version of Backendless? 

4.0 Version

Here’s the file upload API documentation for Android:

After reading through the file upload documentation, I have realized that the magazines are represented as objects not files. I want the magazines to be stored in a database.

Well, then you should refer to Data Service documentation :slight_smile:
