Answer 1

Use the concept of intent filter for NFC.

What kind of NFC tags are you targetting?

Below is a sample code which starts your activity when the NFC tag is discovered that has stored data in text format.

<intent-filter>
  <action android:name="android.nfc.action.NDEF_DISCOVERED"/>
  <data android:mimeType="text/plain"/>
  <category android:name="android.intent.category.DEFAULT"/>
</intent-filter>
