I was researching and I read that it is necessary or better said, the implementation of JobIntentService due to the appearance of android Oreo and its limitations or new restrictions with respect to services in Background , says that the It is responsible for verifying or managing the services or actions of the same (which is what is not clear to me) and executing them in a task queue according to the version of android , which until now I do not get is a basic example of the implementation of this, could someone give me some guidance regarding this? thanks in advance
