In this chapter, we will create some applications that are actually used in real-life scenarios. We can use them on a daily basis to simplify repetitive tasks.
For simplicity purposes, the methods related to tags and NDEF Records handling, which we used in Chapter 2, Detecting a Tag, and Chapter 3, Writing Tag Content, were placed in the NfcHelper class. This class will to be used in every Android-related recipe and is described in the following code:
public class NfcHelper {
public NfcHelper(Activity activity){...}
public boolean isNfcEnabledDevice(){...}
public boolean isNfcIntent(Intent intent){...}
public Tag getTagFromIntent(Intent intent){...}
public void enableForegroundDispatch(){...}
public void disableForegroundDispatch(){...}
public boolean writeNdefMessage(Intent intent, NdefMessage ndefMessage){...}
public boolean writeNdefMessage(Tag tag, NdefMessage ndefMessage){...}
private boolean formatTag(Tag tag, NdefMessage ndefMessage){...}
public...
