Hands-On with Host Card Emulation
summary
Shows how to implement Android Host Card Emulation (HCE): add an Android service and manifest AID filter, implement processCommandApdu to return bytes or null (then call sendResponseApdu later) and use IsoDep.transceive for reliable APDU exchanges. Notes Android 4.4 introduced HCE, Android 7 added Felica (NFC‑F) emulation, and that NFC‑F emulation requires the app to be foreground while NFC‑A HCE can run in background; a demo reads the emulated string from a reader.
