# Document collaboration samples for Android

Discover how to implement realtime collaboration with a server in any language of your choice. Explore examples with WebSocket, Node.js, SQLite3, and Firebase backends. Source code available for downl

In realtime collaboration, a server will merely act as an online database that triggers events upon data creation/modification/deletion. As long as the above requirement is met, your server can be built in any language and stack of your choice. Apryse provides an interface that will allow you to connect your data to the out-of-box UI.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.apryse.com/android/collaboration/samples.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
