Hello everybody,

I’m wondering if there isn’t any documentation about the JSON strings / objects which get sent between OpenVidu server and android clients. I couldn’t found any documentation on those. Currently I’m developing an android app which is based on the [openvidu-android](https://docs.openvidu.io/en/2.21.0/tutorials/openvidu-android/) tutorial. In there I found the “CustomWebSocket” with two methods: “handleServerEvent” and “handleServerResponse” which are working with the JSON objects mentioned above.

Does anyone know if there is proper documentation of those JSON strings and objects or do I have to debug every message by myself?

Kind regards,
