Return a query without LiveData

Question

Basically what I want to do is when I open my app It'll make a query to get a value from the database and use it.

I'm using Room and when I try not to use LiveData it tells me Cannot access database on the main thread since it may potentially lock the UI for a long period of time , so I wonder how could I avoid using LiveData, because if I use it (if I understood right) I can't just pick the information from the database - I have to wait until something changes and only then I'd have access to the query results.

Answer 1

So I found a simple solution.

Because I just want this query used once - on app startup, I just enabled Room database to use the main thread using the allowMainThreadQueries() function.

You're welcome to post here your solution if you think it's better, it would be appreciated.
