TLDR : I am looking for a way to expose a POST endpoint from an android app, is this possible ? If so how ?

Long story :

I want to receive data from arudino devices on my android app. So I want a way to get this data through wifi (that may be a wrong assumption) but without internet connection. My current idea is to post the data from the arduino to the smartphone over wifi.

The thing I don't know and I didn't find answer yet is : can I get data send to my hotspot wifi inside my app ?

Thank you for any lead.

Regards.

To host endpoints inside your Android application you will need a sever to serve those endpoints. You can use the NanoHttpD for this.
