Attributes

Remarks

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(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(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.
