* ``android.intent.action.VIEW`` connected to .gpg and .asc files: Import Key and Decrypt

#### OpenPGP Keychain special registered Intents:
* ``android.intent.action.VIEW`` with URIs following the ``openpgp4fpr`` schema. For example: ``openpgp4fpr:718C070100012282``. This is used in QR Codes, but could also be embedded into your website. (compatible with Monkeysphere's and Guardian Project's QR Codes)
* NFC (``android.nfc.action.NDEF_DISCOVERED``) on mime type ``application/pgp-keys`` (as specified in http://tools.ietf.org/html/rfc3156, section 7)
### OpenPGP Remote API
To do asyncronous fast encryption/decryption/sign/verify operations bind to the OpenPGP remote service.
The API Demo contains all required AIDL files and a demo activity.
