Android. Repository from data layer with global lifecycle

I have a project that currently supports MVP and MVVM. Coroutines, hilt, repository pattern are also used. I need single resources that I will cache.

For example, activity A executes a network request, the user can go to activity B during the execution of the request. However, I need that, regardless of whether I left activity A or not, the network request continues its execution and cache data.

I have a repository that contains the logic for executing a request and caching it. I also tried to provide the repository with the @Singleton annotation using the hilt.

However, as soon as I switch from activity A to activity B, the network request stops executing and no data is stored in the cache.

I understand that what I have done is not sufficient to make the network request be executed in the background even if I leave the activity, but unfortunately I do not understand how I can implement this.

I also read that it is possible to use the same repository instance in the view models of activity A and activity B. But what if it is possible to switch from activity A to many other activities, then I should use the repository instance in the view models of all activities? In addition, my problem is that one activity can have a view model, and another presenter, because. still not the whole project migrated to MVVM.

I tried to find some information on the Internet, but I did not find anything like it.

Please help me. Perhaps someone can share interesting sources with a similar implementation.

Use GlobalScope coroutine to make the request last as long as the Application but you can also use workmanager to make the request and cache it.

For GlobalScope refer to: https://kotlin.github.io/kotlinx.coroutines/kotlinx-coroutines-core/kotlinx.coroutines/-global-scope/

For WorkManager refer to: https://developer.android.com/topic/libraries/architecture/workmanager
