问题 Note: This question assumes you know binding a service to a context. Everyone on the production is aware of this issue, or even some users that have an Android Oreo or Pie device.

问题 I have a started service that handles a connection and that keep an array of objects. On the other hand, I have a singleton that should bind to that service in order to get one of the objects handled by the service. So, how could I bind the service from the singleton?

I have a service in Android that encapsulates a framework that has a start method.
