It mostly runs great, good work!
I started testing it and I noticed a problem: when you search for a depiction (depiction1) select it, then empty the text from the search bar (for instance to search for another depiction depiction2), the selected depiction1 is not visible anymore.

Prince-kushwaha · 2021-04-18T03:26:43Z

ok I fix it

nicolas-raoul

The problem I mentioned in my previous comment seems to be fixed, thanks! :-)

What is the equivalent class for categories? (the DAO that saves previously selected categories)

I noticed a small bug:

Feel free to either fix it now, or create a new issue to solve later, as it is not a big issue compared to the merits that history brings.

to get the context here, you have passed application at the beginning of method calls. No need to pass Application, just pass the context.

Why do we need to create a new Database? Why are we not using the existing database and adding a table in that?

@Prince-kushwaha Thanks for the PR, even though this PR solves the issue, I would very much recommend to rediscuss the approach on the thread and probably revise the PR with the suggestions

Why are we passing the context to the presenter? Let it be the other way around, the presenter should ask the view for the things which need context

We have dagger in place for DB read write operations, we need not worry about the context, please refer other similar classes to see how we have used the corresponding DAO's to query the DB

This is not needed I guess, Room handles the threading part on its own, even if it does not why make a separate class and not let the callers switch threads as needed?

We should ideally avoid static variables, can this not be done via callbacks?

i thing no can you tell me other way

It has to be done with "callbacks". You can basically search how to avoid static variables and how to use callbacks and you will find several online examples that shows you the required structure.

@ashishkumar468 contributionDao is implement in nice way i change DepictsDao like this and use AppDataBase to store table
AppDatabase file is in db folder contribution data is also save in AppDataBase

@ashishkumar468 Room need thread except livedata for threading what i use kotlin coroutines or rxandroid ?
