Using NFC part 1

I try to develop simple NFC application.

Describe the parameters needed to AndroidManifest.xml

Add the necessary permissions to use an NFC Hardware.

?

1 2	<uses-permission android:name="android.permission.NFC"> </uses-permission>

When up to AndroidMarket, uses the terminal to be visible only to add the feature NFC-featured.

?

1 2	<uses-feature android:name="android.hardware.nfc" android:required="true"> </uses-feature>

If you want to handle the NFC tag in Activity, add intent-filter.

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

<intent-filter>   <action android:name="android.nfc.action.NDEF_DISCOVERED">   <data android:mimetype="mime/type"> </data></action></intent-filter>     <intent-filter>   <action android:name="android.nfc.action.TAG_DISCOVERED"> </action></intent-filter>   <intent-filter>   <action android:name="android.nfc.action.TECH_DISCOVERED"> </action></intent-filter> <meta-data android:name="android.nfc.action.TECH_DISCOVERED" android:resource="@xml/nfc_tech_filter"> </meta-data>

You should describe only necessary .

and add 'nfc_tech_filter.xml' in yout project, that you want to receive NFC tag in your Activity.
