i filter the intent like this
<intent-filter>
<action android:name="android.nfc.action.NDEF_DISCOVERED"/>
<category android:name="android.intent.category.DEFAULT"/>
<data android:mimeType="text/plain" />
now the problem is, when i discover the Ndef tag near to my mobile the event which i implemented in my application is running(even my application at close state).
How to stop this one?
Use the ForegroundDispatchSystem.
