MutableLiveData: Cannot invoke setValue on a background thread from Coroutine

Question

I\'m trying to trigger an update on LiveData from a coroutine:

object AddressList: MutableLiveData>()
fun getAddressesLiveData(): L         


        

Answer 1

If you want to updated UI by using Coroutines, there are 2 ways to achieve this

GlobalScope.launch(Dispatchers.Main):

GlobalScope.launch(Dispatchers.Main) {
    delay(1000)     // 1 sec delay
    // call to UI thread
}

And if you want some work to be done in background but after that you want to update UI, this can be achieved by the following:

withContext(Dispatchers.Main)

GlobalScope.launch {
    delay(1000)     // 1 sec delay

    // do some background task

    withContext(Dispatchers.Main) {
            // call to UI thread
    }
}
