Question

gt But as standalone coroutines are deprecated what other alternatives do we have apart from GlobalScope What do you mean GlobalScope is direct successor of old standalone coroutine builders and provides the same lifecycle But usually you don t need it use CoroutineScope everywhere where it s possible to do gt has examples about `runBlocking ` and `GlobalScope launch ` only It s just for simplicity of examples docs has actually a lot of different examples not only runBlocking or GlobalScope

Here I am asking for alternatives for CoroutinesContext builders other than GlobalScope As Kotlin Coroutines are new as far I know I could not find enough resources to clear my doubts

gildor · Answer

alternatives for CoroutineContext builders What do you mean

Rohit Surwase · Answer

Like as GlobalScope is application wide what if I want to create a Coroutines context specifically for a dialog

gildor · Answer

Okay first of all it s not a Coroutine context

gildor · Answer

CoroutineContext is like metadata for coroutine used to provide configs to coroutines

gildor · Answer

If you have some custom lifecycle you have 2 options 1 Create CoroutineScope just for this lifecycle and run coroutine there + UPD You should of course do not forget to cancel scope when your dialog cancelled 2 Create a new coroutine in parent level lifecycle but cancel it manually start coroutine get Job instance and cancel this job on dialog cancel

gildor · Answer

case with custom CoroutineScope make sense for me if you run multiple coroutines there otherwise one single Job for one single coroutine looks fine for me

gildor · Answer

If you talking about Android you shouldn t use GlobalScope only if you run something on Application level only scopes related to Activity Fragment lifecycle
