I have my own mobile app aka modul. The second modul is wear. I wrote UI in wear modul but I don’t know how to connect to wear modul to app modul for usecases sharing. Can somebody point me on some sources? I tried github, medium, google, documentation, YT, and I still can’t find a good source for the correct connection of the wear module to the mobile app module where I have already written usecases. It’s simple app aka weather app.

You should have (at least) a third module (for your use cases) upon which the app module and the wear module depend.

Yes. I can make core module with the use cases. But please do you have some advice for good source of tutorials or something like this?

Do you mean for how to structure overall or how to extract code from existing modules?

For example if it's help me to connect correctly wear modul to other one

I can't remember the names, but two handsome smart gentlemen gave a talk on this exact topic at ADS.

this your nice and great video I’ve seen that before. Unfortunately, it’s only theoretical for me. I guess I’m not very smart. I’m looking for a practical guide. 1 module with an application for obtaining data, e.g. about free parking spaces. 1. the wear module gets data from the core (or app) module and just displays it.

Can you start by moving logic to a core module?

yes .. no problem

Maybe, work through this example https://github.com/android/wear-os-samples/tree/main/DataLayer can be a help, if you are asking for exchanging data between the two devices. This link can also be a help https://developer.android.com/training/wearables/data/data-layer, there used to be some good codelab for DataLayer in the past for java.

Thank you so much all of them guys. Looking forward to this nice adventure 😍
