Botpress is a standalone server, so you need to have botpress running somewhere (cloud, local machine etc…)
Then your android app can send request to your botpress server which will send you informations back which you can then handle in your app.
Android app get “Can i book a plane to tokyo the 5th for 400$ ?”
-----http call to botpress-----
botpress gives // intent : book plane, price:400, date 5th, place : tokyo
----- Android app receive the information -----
Show a table or anything with this information in your app
(Quick research : it seems possible to run nodejs on android… but we do not officially support that, if you want to try to run botpress directly on android you could try and give me some feedback but be careful, botpress needs some power… the easy way is to have botpress running on a real server)
