    <p>Hi i am developing an android application using NFC feature. Here i tried to read NFC Mifare nfc tag. I used NFCDemo which is available with android api.But i did not get success to read data through my application. In that demo that is always reading fake tags and giving fake result only.</p> <p>I have a confusion about the manifest file intent filters. In my demo application is like this</p> <pre><code>&lt;manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.android.nfc" &gt; &lt;uses-permission android:name="android.permission.NFC" /&gt; &lt;uses-permission android:name="android.permission.CALL_PHONE" /&gt; &lt;application android:icon="@drawable/icon" android:label="@string/app_name" &gt; &lt;activity android:name=".simulator.FakeTagsActivity" android:theme="@android:style/Theme.NoTitleBar"&gt; &lt;intent-filter&gt; &lt;action android:name="android.intent.action.MAIN" /&gt; &lt;category android:name="android.intent.category.LAUNCHER" /&gt; &lt;/intent-filter&gt; &lt;/activity&gt; &lt;activity android:name="TagViewer" android:theme="@android:style/Theme.NoTitleBar" &gt; &lt;intent-filter&gt; &lt;action android:name="android.nfc.action.TAG_DISCOVERED"/&gt; &lt;category android:name="android.intent.category.DEFAULT"/&gt; &lt;/intent-filter&gt; &lt;/activity&gt; &lt;/application&gt; &lt;uses-sdk android:minSdkVersion="9" /&gt; &lt;uses-feature android:name="android.hardware.nfc" android:required="true" /&gt; &lt;/manifest&gt; </code></pre> <p>And the application is always starting with FakeTagsActivity activity any showing list of fake tags.When we click on any one of the fake tags it will redirect to TagViewer activity with fake data not the real tag data. I have confusion too in TagViewer activity also that is resolveIntent(Intent intent) is handling always </p> <pre><code>if (NfcAdapter.ACTION_TAG_DISCOVERED.equals(action)) {} </code></pre> <p>but i am not understanding whats the wrong with this. Please advice me am i need to modify the api demo to read real tag data. Or advice me is there any other way to read the nfc tag.</p> <p>I already tried <a href="http://mifareclassicdetectiononandroid.blogspot.in/2011/04/reading-mifare-classic-1k-from-android.html" rel="nofollow">This Sample</a> but not help full for me. Please help me. Thanks in advance.</p>

    1. COWhen you say it "doesn't work", are you trying on a real device? Are you sure that device has NFC hardware support in it?

    3. COThe NFCDemo app is really outdated, I wouldn't use it to build off of. But, lets try to figure out the problem first. You are saying that when you click on one of the fake tags it goes to TagView activity with the fake data. That is expected. At what point do you actually scan your tag? I didn't catch in your question when you did that.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
