how to send a data between two android app one of them is unity game

Question

I am trying to make an android game (using unity game engine) and I want this game to have a speech recognition feature. I want to make speech recognition using android application which uses google API, but I want to send the result of recognition to another app which is the unity game.

How can I do it ? Is it valid ? P.S.: I know that google provides a plugin for unity but I do not want to use it.

Answer 1

You can use Services. Bounded services with a Messenger that will serve as the mediator between the remote and local process or with AIDL interface. You can also create a receiver on the remote process to receive the service obtained and a service(the sender).
