I am still learning the Android API.
Could someone give me some guidelines for using the Android API to enable NFC read tags?
What are the major items that have to happen in order to read the content of message?
What is the sequence of things that are supposed to happen? Does someone has a few lines of sample code?
For instance:
How to read the intent filter: do I use "PendingIntent"?
Does the app need to be able to handle exception? If yes, how.
How to use "NfcAdapter".
This is what you need to get started. Read the basics section and you should be off :)
Check out this NFC workshop series. this will help you.

I would like to open this directly from my program, is it possbile?
I checked this, but cannot found relevant information
https://developers.google.com/maps/documentation/android-api/intents
If it is impossible, is there any alternative way?
You can't do that from your activity.
In the image above you can see a dialog that catches the voice of the user, this is because Google Maps calling an intent ACTION_RECOGNIZE_SPEECH, and you can't start an intent and after calling Maps.
Here is the only documentation that I found on the internet for that question. The Adding Voice Capabilities. Just remember that these voice actions are task-based and are built into the Wear platform. So you need to use Android wear for that, see Maps API on Android wear.
Just read the two documentation to understand more. Also take note, that do not violate any terms of service on the Google Maps. Here is one example question for that.
So far, I have not used this voice capablities, so I'm not sure if it will really help you, but I think I give you a small idea with it. Goodluck and Happy coding :)
i want to code an application which enable file sharing via Bluetooth with android, but i can't find samples which i can base on. Please can someone give me links to some samples.
There is really a lot of info all over the place about this.
A good starting point is always the documentation it also has examples too!
As was mentioned a quick google search should have given you a lot of examples programs but here is one anyways.
I need to read RFID tag and use it as a bar-code system. How to read RFID by using an Android device? Please guide me.
This topic is too big to be addressed here. Here is a presentation that can get you started.
NFC is a type of RFID and I think that is what you actually want to know about. Since some Android devices support NFC.
I was also going through the R&D process that how to read RFID tags on Android, So I found some useful links which describes how exactly it works.
For basics understanding go here & for demo Application it has very good explanation
I found lots of books on android which give basic concept on android Example (calling Activity, Intent, service, broadcast receivers etc). But I want to know brief description on all these concept. in os level or in api level how does it work. Also how connection with wifi or 3g works in api level.
I want to know brief understanding on android. Can anyone suggest any tutorial or book to get detail understanding on android.
Thanks
Start with the Android Developer's Guide. http://developer.android.com/guide/index.html
I would recommend to buy a book. For me Professional Android 2 Application Development was really good. But probably now there is better (up to date) alternative.
Anyway I find reading books much easier starter than separate tutorials and articles.
If you want a really detailed view, just look at the source code.
