feat: create UI library module

[AliYusuf95]

Solve #117

• [x] Create UI library module
• [x] Prefix resources used in UI
• [x] Use the module in the app

[or-else]

I would suggest a more unique name for the library, such as co.tinode.tindroidui. There is certainly no need for an additional namespace android in the name of the module (co.tinode.android...).

[AliYusuf95]

That's fine @or-else What about resources prefix should I use tindroid_ui_ or tindroidui_.

[or-else]

How about naming everything tinui: co.tinode.tinui and tinui_? It's short, unique (no such modules exist at maven). What do you think?

[AliYusuf95]

I think it's good. By the way I prefer that the UI module naming should be similar to the SDK module; to be more convenient for the users. In this case the SDK module would be tinsdk?

[or-else]

co.tinode.tinsdk: yes, I like it.

@or-else Currently a lot of features are tightly coupled with the application like (Contacts sync, Chats lists, Messages, etc.) We need to have a list of features that should be in the UI module and the rest can be considered either plugins or as application customization.

Currently this is what my mind for UI:

• [ ] Chats lists
• [ ] Messages
• [ ] Images preview
• [ ] Attachments

[or-else]

I'm not concerned with the app being tightly coupled with the SDK and UI libraries. I do not foresee a case where I would want to swap this UI library for another in the app. So, the app is not of concern, the tinui is.

Let's take a step back: what is the intended use case for the tinui? I imagine that the use case for it is to be usable as components when building another chat app, like tindroid. If so, there is no clear line between the app and the UI library. The library can start small, as a set of a few clearly separable components. We can gradually move components from the app to the lib over time.

[AliYusuf95]

Exactly this is what I'm trying to achieve.

What I understand that not every component will add to tinui will be used right away in the app. So it doesn't have to contain all features that used in the app. Ideally over time the app will rely on tinui components. As you said this will give the freedom to gradually add more components to the lib.

[or-else]

Great, we agree.

I would start with creating components for message bubbles.

[or-else]

Then contact display.

This PR seems to be getting stale. Should I close it?

[AliYusuf95]

@or-else I was bit busy last month, but I made some progress creating some views and feed them from Tinode instance. I'll try to push finished parts by next week.

[or-else]

Thanks for the update.

[AliYusuf95]

@or-else Currently, I'm overwhelmed with changing job process. I'll pause my work in this PR until I settle in the new job.

[or-else]

Is this still relevant?
