NFC intent Filter => I/NfcDispatcher(923): Connect to a tech with a different handle

android, android-intent, nfc

Solution

Ok, here is the correct Intent Filter:

<intent-filter>
    <action android:name="android.nfc.action.TECH_DISCOVERED"/>
    <meta-data android:name="android.nfc.action.TECH_DISCOVERED"
        android:resource="@xml/nfc_tech_filter" />
</intent-filter>

<intent-filter>
    <action android:name="android.nfc.action.TAG_DISCOVERED" />
    <category android:name="android.intent.category.DEFAULT" />
</intent-filter>

Problem

I am working on an NFC application that works perfectly with some VCard tags. Now, I would like to use some differents tags that the customer sent me. The Android device (Nexus 4 and Galaxy Nexus) are just making the NFC beep, but no app appears, no intent chooser... Here is my Manifest entry for the Intent: ``` <activity android:name=".ResultActivity" android:label="Alcatel Scan" android:theme="@android:style/Theme.Holo.NoActionBar.Fullscreen" > <intent-filter> <action android:name="android.nfc.action.NDEF_DISCOVERED" /> <category android:name="android.intent.category.DEFAULT" /> </intent-filter> </activity> ``` And here is the associated logcat when I scan the tag: ``` 12-28 12:29:35.599: D/ACDB-LOADER(164): ACDB -> send_afe_cal 12-28 12:29:35.609: D/NativeNfcTag(923): Connect to a tech with a different handle 12-28 12:29:35.619: D/alsa_ucm(164): Set mixer controls for HiFi Lowlatency enable 1 12-28 12:29:35.619: D/ALSAModule(164): Device value returned is hw:0,14 12-28 12:29:35.629: D/ALSAModule(164): setHardwareParams: reqBuffSize 1024 channels 2 sampleRate 48000 12-28 12:29:35.629: D/ALSAModule(164): setHardwareParams: buffer_size 2048, period_size 1024, period_cnt 2 12-28 12:29:35.639: D/NativeNfcTag(923): Check NDEF Failed - status = 3 12-28 12:29:35.639: D/NfcDispatcher(923): dispatch tag: TAG: Tech [android.nfc.tech.NfcV, android.nfc.tech.NdefFormatable] message: null 12-28 12:29:35.669: I/NfcDispatcher(923): no match ``` According to this line: "Connect to a tech with a different handle" I really fear that the tag will never be readable by an Android device.. Am I wrong? Thank a lot for any help
