How to make application as default

[kamalmjan]

Hi all,

Currently when I scan an RFID tag, a selection menu will pop up showing all the nfc applications installed on the droid. However, my application is not listed. I've added the following in the manifest file:

AddActivityText(main,
<intent-filter >
<action android:name="android.nfc.action.NDEF_DISCOVERED"/>
<category android:name="android.intent.category.DEFAULT"/>
<data android:mimeType="text/plain" />
</intent-filter>)

However, my application is still not listed. How do I go about resolving this problem? All hep is greatly appreciated. Thanks!

Brgds,
Kamal

I've added the following in the manifest:

AddActivityText(main, 
   <intent-filter >
      <action android:name="android.nfc.action.TAG_DISCOVERED"/>
      <category android:name="android.intent.category.DEFAULT"/>
      <data android:mimeType="text/plain" />
    </intent-filter>
    <intent-filter>
        <action android:name="android.nfc.action.TECH_DISCOVERED" />
      <category android:name="android.intent.category.DEFAULT"/>
      <data android:mimeType="text/plain" />
    </intent-filter>
   <meta-data android:name="android.nfc.action.TECH_DISCOVERED"
         android:resource="@xml/nfc_tech_filter"
    />)
AddPermission (android.permission.NFC)

And added the following res\xml\nfc_tech_filter.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <tech-list>
        <tech>android.nfc.tech.IsoDep</tech>
    </tech-list>
    <tech-list>
        <tech>android.nfc.tech.NfcA</tech>
    </tech-list>
    <tech-list>
        <tech>android.nfc.tech.NfcB</tech>
    </tech-list>
    <tech-list>
        <tech>android.nfc.tech.NfcF</tech>
    </tech-list>
    <tech-list>
        <tech>android.nfc.tech.NfcV</tech>
    </tech-list>
    <tech-list>
        <tech>android.nfc.tech.Ndef</tech>
    </tech-list>
    <tech-list>
        <tech>android.nfc.tech.NdefFormatable</tech>
    </tech-list>
    <tech-list>
        <tech>android.nfc.tech.MifareClassic</tech>
    </tech-list>
    <tech-list>
        <tech>android.nfc.tech.MifareUltralight</tech>
    </tech-list>
</resources>

but still my program is not listed. This is what pops up on my droid when I scan the tag:

Appreciate the help. Thanks.

Try changing this <data android:mimeType="text/plain" /> to <data android:mimeType="text/*" /> or removing that line altogether.
Or alternatively open the manifest of one of the listed apps and see what they have set as the intent filter.
