β Use async{} coroutine block for handling the exception because it will specifically return the error to you after awaiting for the code block to execute. But it is not the best idea and you should not use it but it still better than try/catch
β When you use multiple scopes by launch{} block in coroutine scope please make sure you are using supervisor scope else whenever a scope gets an exception the below scopes will not be executed else it will cancel all the scopes under it. By using supervisor scope only faulty scope will be canceled and below scopes will be executed.
β Best practice use CoroutineScopeExceptionHandler in the scope which is the best way of doing this. It is better than async or try/catch and it is the only way of doing it properly.
β If you want to work with a list of tasks please make sure doing in sync way, one by one else you have to handle everything manually and the sequential task might fail due to this.
β Do not use GlobalScope unless you really needs it.
β If you want to get a list of exceptions from a nested coroutine scope please make sure you are using the supervisor scope else you will get only the top exception and do not use try/catch use the Coroutine Scope exception handle for the launched scopes.
