NfcNci Patience

Add a delay (1000ms by default) to the NFC presence check to accommodate longer NFC smart card operations in AOSP NfcNci implementation on certain devices (see LineageOS issue #7268)

This bug —which may sound obscure at first, plagues several apps e.g. the German eID app and most of Indonesian electronic pass (Mandiri e-money, BCA Flazz, etc) recharge apps (failure upon balance update) due to those apps not having sufficient EXTRA_READER_PRESENCE_CHECK_DELAY value, which results in the NFC service’s assumption that the smart card has been lost.

Setup

• Install this module
• Enable this module and ensure that “Nfc Service” (the com.android.nfc package) is added to the scope
• Reboot the device for the module to take effect

Configuration

You can use the provided settings interface to tune the presence check timeout to your needs, provided that they’re a whole number ranging from 125 to 5000. You do not need to reboot your device for the change to take effect.
