在 android 设备上检测 NFC

Question

Well, my purpose is to detect if the Android device supports NFC and if not I will use some other technology. I have set my minimum API level to 8 as I want my app to function even on these devices without NFC.

Is there a method like isNFCSupported()? any ideas?

thanks yosoh.

Step #1: Put this in your manifest:

<uses-feature android:name="android.hardware.nfc" android:required="false" />

Step #2: Call hasSystemFeature(PackageManager.FEATURE_NFC) on PackageManager to see if NFC is available on the current device
