How to read NFC tag data globally inside an Android Application -

-

I would like to read NFC tag data inside my application. Basically I have different NFC tags associated with different actions that perform inside my application. It's a bad idea to declare me intent filter inside service I do not want to associate it with any activity .

Here I appear: 

  & lt; service android: name = "com .yo.helpers.NFCReaderHelper" Android: Enabled = "True" Android: export = "true" & gt; & Lt; Intent-Filter & gt; & Lt; Action Android: name = "android.nfc.action.NDEF_DISCOVERED" /> & Lt; Category android: name = "android.intent.category.DEFAULT" /> & Lt; Data Android: scheme = "http" /> & Lt; / Intent-Filter & gt; & Lt; Intent-Filter & gt; & Lt; Action Android: name = "android.nfc.action.NDEF_DISCOVERED" /> & Lt; Category android: name = "android.intent.category.DEFAULT" /> & Lt; Data Android: mimeType = "text / plain" /> & Lt; / Intent-Filter & gt; & Lt; / Services & gt;   
 Here is my service class:  
  @override protected void handelist (intent to intent) {Log D ("योओ", "service") ; Tag mTag = null; If (intent.getAction ()! = Null) {if (intent.getAction (.) Equals ("android.nfc.action.NDEF_DISCOVERED")) log D. ("Yo", "Intention Call"); MTag = (tag) intent.getParcelableExtra (NfcAdapter.EXTRA_TAG); Logs. I ("tag id", bytefxstring (mTag.getId ()); }}   
 I did not receive the call within the  onHandleIntent  method. If I do this within a  activity , then I get intent within the  onNewIntent  method   
 
 
 You can not obtain NFC discovery intents ( NDEF_DISCOVERED ,  TECH_DISCOVERED with a service (or a broadcast receiver) ,  TAG_DISCOVERED ) On Android, NFC is designed as a means of interacting with the user and therefore, these intentions are distributed only on the activities Has been played.  
 A trick that you can use, is to use an invisible / transparent activity to handle the intent

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i
