How Can I Initialize My HostApduService from an Activity?

I need to initialize my HostApduService with an ApduResponse object, the responses in processCommandApdu will be created using this ApduResponse object. I want to initialize my HostApduService after I get response from network to create my ApduResponse object. How Can I achieve that?

As explained in the doc, HCE service is launched when Reader with specific AID is tapped to your device(HCE). https://developer.android.com/guide/topics/connectivity/nfc/hce.html#HceServices

One of the key advantages of a service is that it can run in the background without any user interface. This is a natural fit for many HCE applications like loyalty or transit cards, with which the user shouldn't need to launch the app to use it. Instead, tapping the device against the NFC reader starts the correct service (if not already running) and executes the transaction in the background. Of course, you are free to launch additional UI (such as user notifications) from your service if that makes sense.

To send specific ApduResponse to your service, you need to communicate between your application and your HCE service. Please read this : Passing information to a HostApduService from another Context
