android-nfc-wrapper

Project cloning + wrapping black- and greylisted Android NFC (android.nfc) classes.

Features:

• Clones a lot of NFC-related interfaces (aidls) and classes, like Ndef, Tag and IsoDep
• Adds wrappers so that the cloned source works in parallel with the native sources

Advantages:

• external readers can use the same pattern as internal NFC (i.e. parcelable objects reconnecting to services on deserialization).
• working with dual NFC stacks is simplified, even on the latest Android; independent of which classes will be grey- or blacklisted later.

Disadvantages:

• increased footprint due to additonal (duplicated) classes
• does not work out of the box with third party libraries - they must be modified / recompiled to work. This can be solved with a custom processor, but this is yet to be implemented.
