QUESTION
My app is checking for unread emails in the background, the problem is that i need to save and retrieve lastCheckedDate when i last checked for emails so i can show only newly received emails.
For retrieving data from datastore i use observeLastCheckedDate() and i must call it with handler because if i dont i get:
java.lang.IllegalStateException: Cannot invoke observe on a background thread
Function observeLastCheckedDate() get called but while it finish(updates lastCheckedDate), workManager task is already finished with not-updated var lastchecked date.
In main class i avoid this problem by creating and invoking callback but here that does not work(it makes whole app freeze), so we somehow need to wait for that function to finish or get some new way of retreiving data from datastore.

there is an alternative CoroutineWorker to extend your class from it instead of Worker
it will provide you with suspending version of doWork() function
