NfcFCardEmulation

disableService

fun disableService(activity: Activity!): Boolean

Disables the service for the specified Activity.

Note that the specified Activity must still be in resumed state at the time of this call. A good place to call this method is in your Activity#onPause implementation.

enableService

fun enableService(
    activity: Activity!, 
    service: ComponentName!
): Boolean

Allows a foreground application to specify which card emulation service should be enabled while a specific Activity is in the foreground.

The specified HCE-F service is only enabled when the corresponding application is in the foreground and this method has been called. When the application is moved to the background, disableService(android.app.Activity) is called, or NFCID2 or System Code is replaced, the HCE-F service is disabled.

The specified Activity must currently be in resumed state. A good paradigm is to call this method in your Activity#onResume, and to call disableService(android.app.Activity) in your Activity#onPause.

Note that this preference is not persisted by the OS, and hence must be called every time the Activity is resumed.

getInstance

static fun getInstance(adapter: NfcAdapter!): NfcFCardEmulation!

Helper to get an instance of this class.

getNfcid2ForService

fun getNfcid2ForService(service: ComponentName!): String!

Retrieves the current NFCID2 for the specified service.

Before calling setNfcid2ForService(android.content.ComponentName,java.lang.String), the NFCID2 contained in the Manifest file is returned. If "random" is specified in the Manifest file, a random number assigned by the system at installation time is returned. After setting an NFCID2 with setNfcid2ForService(android.content.ComponentName,java.lang.String), this NFCID2 is returned.

getSystemCodeForService

fun getSystemCodeForService(service: ComponentName!): String!

Retrieves the current System Code for the specified service.

Before calling registerSystemCodeForService(android.content.ComponentName,java.lang.String), the System Code contained in the Manifest file is returned. After calling registerSystemCodeForService(android.content.ComponentName,java.lang.String), the System Code registered there is returned. After calling unregisterSystemCodeForService(android.content.ComponentName), "null" is returned.

registerSystemCodeForService

fun registerSystemCodeForService(
    service: ComponentName!, 
    systemCode: String!
): Boolean

Registers a System Code for the specified service.

The System Code must be in range from "4000" to "4FFF" (excluding "4*FF").

If a System Code was previously registered for this service (either statically through the manifest, or dynamically by using this API), it will be replaced with this one.

Even if the same System Code is already registered for another service, this method succeeds in registering the System Code.

Note that you can only register a System Code for a service that is running under the same UID as the caller of this API. Typically this means you need to call this from the same package as the service itself, though UIDs can also be shared between packages using shared UIDs.

setNfcid2ForService

fun setNfcid2ForService(
    service: ComponentName!, 
    nfcid2: String!
): Boolean

Set a NFCID2 for the specified service.

The NFCID2 must be in range from "02FE000000000000" to "02FEFFFFFFFFFFFF".

If a NFCID2 was previously set for this service (either statically through the manifest, or dynamically by using this API), it will be replaced.

Note that you can only set the NFCID2 for a service that is running under the same UID as the caller of this API. Typically this means you need to call this from the same package as the service itself, though UIDs can also be shared between packages using shared UIDs.

unregisterSystemCodeForService

fun unregisterSystemCodeForService(service: ComponentName!): Boolean

Removes a registered System Code for the specified service.
