Detecting NFC Tags

Unity Engine

I’m trying to detect and read any NFC tag that gets near the device.

I modified the AndroidManifest.xml to add the NDEF and TAG discovered intent filters to the UnityPlayerProxyActivity.
Also added nfc permissions at the end

        .......

        <activity android:name="com.unity3d.player.UnityPlayerProxyActivity" android:screenOrientation="sensorLandscape"
                  android:label="@string/app_name"
                  android:configChanges="fontScale|keyboard|keyboardHidden|locale|mnc|mcc|navigation|orientation|screenLayout|screenSize|smallestScreenSize|uiMode|touchscreen">            			
			<intent-filter>
			    <action android:name="android.nfc.action.NDEF_DISCOVERED"/>
			    <category android:name="android.intent.category.DEFAULT"/>
			</intent-filter>
			<intent-filter>
				<action android:name="android.nfc.action.TAG_DISCOVERED"/>
				<category android:name="android.intent.category.DEFAULT"/>
            </intent-filter> 
			<intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

</application>

		<uses-permission android:name="android.permission.NFC" />
		<uses-feature android:name="android.hardware.nfc" />
  		<uses-sdk android:minSdkVersion="9" android:targetSdkVersion="15" />	
</manifest>

then on a unity script I’m running the following code:

	public void Update()
	{
		AndroidJavaClass JClass1 = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
		AndroidJavaObject mActivity = JClass1.GetStatic<AndroidJavaObject>("currentActivity");
		AndroidJavaObject mIntent = mActivity.Call<AndroidJavaObject>("getIntent");
		string sAction = mIntent.Call<string>("getAction");
		Debug.Log(sAction);
	}

The problem is that sAction is never “android.nfc.action.NDEF_DISCOVERED”. In fact its never different from “android.intent.action.MAIN”

Am I missing something. Do I need to write a java class inheriting from UnityPlayerActivity?

As soon as a NFC tag gets near the device, a popup appears telling me that it has collected an Empty Tag but my app doesn’t return a different intent or action string.

Any help will be awesome!

Any update on this? I’m currently having the same problem…
