Your manifest file needs to handle tech discovered intents, in a separately tech filter xml, like this: <pre><code><intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> <intent-filter> <action android:name="android.nfc.action.TECH_DISCOVERED"/> </intent-filter> <meta-data android:name="android.nfc.action.TECH_DISCOVERED" android:resource="@xml/nfc_tech_filter" /> <intent-filter> <action android:name="android.nfc.action.TAG_DISCOVERED"/> </intent-filter> </code></pre> Then your res/xml/nfc_tech_filter.xml must handle the nfc techs you want like this: <pre><code><resources xmlns:xliff="urn:oasis:names:tc:xliff:document:1.2"> <tech-list> <tech>android.nfc.tech.MifareUltralight</tech> <tech>android.nfc.tech.Ndef</tech> <tech>android.nfc.tech.NfcA</tech> </tech-list> <tech-list> <tech>android.nfc.tech.MifareClassic</tech> <tech>android.nfc.tech.Ndef</tech> <tech>android.nfc.tech.NfcA</tech> </tech-list> </resources> </code></pre> Each tech node acts like an AND whereas the tech-list node acts like and OR. I recommend you to first scan your tags with a tool like NFC Tag Reader in order to know your techs. Then in java code you can enable/disable your foreground dispatch system like other sites already techs, I set up the same techs as I did in xml like this: <pre><code>private void setUpForegroundDispatchSystem() { this.nfcAdapter = NfcAdapter.getDefaultAdapter(this); this.pendingIntent = PendingIntent.getActivity(this, 0, new Intent(this, getClass()).addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP), 0); IntentFilter ndef = new IntentFilter(NfcAdapter.ACTION_NDEF_DISCOVERED); try { ndef.addDataType("*/*"); /* Handles all MIME based dispatches. You should specify only the ones that you need. */ ndef.addDataScheme("http"); } catch (MalformedMimeTypeException e) { throw new RuntimeException("fail", e); } this.intentFiltersArray = new IntentFilter[] {ndef}; this.techListsArray = new String[][] { new String[] { MifareUltralight.class.getName(), Ndef.class.getName(), NfcA.class.getName()}, new String[] { MifareClassic.class.getName(), Ndef.class.getName(), NfcA.class.getName()}}; } </code></pre> You must enable and disable this in Pause and Resume methods. Hope that this info helps you.

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.
