243 <p>Android apps can now emulate ISO14443-4 (ISO-DEP) NFC cards that use APDUs for data exchange (as specified in ISO7816-4). This allows an NFC-enabled device running Android 4.4 to emulate multiple NFC cards at the same time, and allows an NFC payment terminal or other NFC reader to initiate a transaction with the appropriate NFC card based on the application identifier (AID).</p>
245 <p>If you want to emulate an NFC card that is using these protocols in your app, create a service component based on the {@link android.nfc.cardemulation.HostApduService} class. Whereas if your app instead uses a secure element for card

254 <p>This new capability, in conjunction with host card emulation, allows Android to operate on both ends of a mobile payment interface: One devices operates as the payment terminal (a device running a reader mode activity) and another device operates as the payment client (a device emulating an NFC card).</p>
429 <p>You can now read and write app-specific files on secondary external storage media, such as when a device provides both emulated storage and an SD card. The new method {@link android.content.Context#getExternalFilesDirs getExternalFilesDirs()} works the same as the existing {@link android.content.Context#getExternalFilesDir getExternalFilesDir()} method except it returns an array of {@link java.io.File} objects. Before reading or writing to any of the paths returned by this method, pass the {@link java.io.File} object to the new {@link android.os.Environment#getStorageState getStorageState()} method to verify the storage is currently available.</p>
