How to Determine if Android Device Supports Host-Based NFC Card Emulation

public static final String FEATURE_NFC_HOST_CARD_EMULATION was added in API level 19
Feature for getSystemAvailableFeatures() and hasSystemFeature(String).
The device supports host- based NFC card emulation.
Constant Value: "android.hardware.nfc.hce"


1. Get a PackageManager Instance named myPackageManager.

2. Create a Boolean Variable named bolHCNFCSupported. 

3. Set the Minimum and Target SDK version  to 19 or greater. 

4. In the onCreate method, add the below code. This will return the host-based NFC ability to a boolean named bolHCNFCSupported. It will then display a toast displaying the host-based NFC ability of the device to the user.

bolHCNFCSupported = myPackageManager.hasSystemFeature(PackageManager.FEATURE_NFC_HOST_CARD_EMULATION);
if (bolHCNFCSupported) {
Toast.makeText(this, "Device has host-based NFC capability", Toast.LENGTH_LONG).show();
} else {
Toast.makeText(this, "No host-based NFC capability!", Toast.LENGTH_LONG).show();
}

5. Compile and run!
