How to Register an Activity that Responds to NFC tags for URI's that point to a URL

This will register an Activity that will respond only to NFC tags that correspond to a URI that points a website (URL).
ACTION_NDEF_DISCOVERED(added in API level 10) is an Intent to start an activity when a tag with NDEF payload is discovered.

1. Add a new activity to your AndroidManifest.xml file. You may add it below  a closing (</activity) tag.

<activity android:name=".BlogViewer">
<intent-filter>
<action android:name="android.nfc.action.NDEF_DISCOVERED"/>
<category android:name="android.intent.category.DEFAULT" />
<data android:scheme="http:"
   android:host="androidsbs.blogspot.com"/>
</intent-filter>
</activity>

2. Compile and run!
