Question

I have some documentation that doesn’t have any intuitive examples for me

http://developer.android.com/reference/android/nfc/tech/NfcV.html

http://developer.android.com/reference/android/nfc/Tag.html

I need to declare objects of type NfcV and of type Tag , but when I try to do something like NfcV myNFCObject = new NfcV(); the IDE says “constructor NfcV is not visible. So my next try looked like this NfcV myNFCObject = NfcV.getTag(new Tag()); and I get the error “constructor Tag()” is not visible.

So thats where I hit a wall, just from looking at both of the documentation links, I do not see how to declare these objects! How would this be done?

Thanks!

Answer 1

Firstly you must create a class which implements TagTechnology interface. Then you can get tag with it.

import java.io.IOException;

import android.nfc.Tag; 

public class sampleTagTech implements android.nfc.tech.TagTechnology {

public void close() throws IOException {
    // TODO Auto-generated method stub

}

public void connect() throws IOException {
    // TODO Auto-generated method stub

}

public Tag getTag() {
    // TODO Auto-generated method stub
    return null;
}

public boolean isConnected() {
    // TODO Auto-generated method stub
    return false;
}

}

then you can use like this

NfcV nfcv = NfcV.get(new sampleTag().getTag());
