Since the release of SDK 8 the required=true inside the timodule.xml forces all the app to have required=true and reduce drastically the device avaiability on play store.

https://jira.appcelerator.org/browse/AC-6328

I've resolved removing the required in the timodule.xml

I am trying to run the TagViewer example on Ti.7.2.0.GA mentioned here:

https://github.com/appcelerator-modules/ti.nfc/tree/master/android/example/TagViewer/app

When the app is not open, and you scan a NFC tag, the app opens under "Nfc Service" as a separate instance, but the data does not show up.

When scanning a tag, while the app is still open, the app is simply re-opens, but again the data does not show up.

The example also mentions to use android:launchMode="singleTask" no longer works and been replaced with the feature <property name="intent-filter-new-task" type="bool">true/false</property>. See docs: https://wiki.appcelerator.org/display/guides2/Android+Intent+Filters#AndroidIntentFilters-Launchmode

Please help and update the docs, as this is an urgent feature we need to roll out soon. Many thanks!

NOTE: I also mentioned this issue on JIRA: https://jira.appcelerator.org/browse/AC-5820 as I wasen't sure where I meant to post issues.

Saw this was an open issue at one point but I'm still not able to receive a valid response on iOS:

Creating [object TiNfcNdefMessage] in a different context than the calling function. { messages = ( "<null>" ); }

This is with "run-on-main-thread" as true. SDK 7.1.0.

I recently attempted to bring a 3 year old project that uses ti.nfc up to date by targeting android 33, updating to Titanium SDK 12.1.2.GA and ti.nfc 5.0.0, but ran into problems scanning NDEF tags that are readable with an old build of my project. Here is my e.inent for a read of a ISO 14443-3A NXP-Mifare Classic 1k tag (Tech: NfcA,MifareClassic,Ndef) tag:

[INFO] Intent {
[INFO] url: undefined,
[INFO] type: null,
[INFO] packageName: 'com.something.something',
[INFO] className: 'org.appcelerator.titanium.TiActivity',
[INFO] action: null,
[INFO] flags: 805306368,
[INFO] data: null,
[INFO] _hasJavaListener: undefined,
[INFO] apiName: 'Ti.Android.Intent',
[INFO] bubbleParent: true
[INFO] }

Reading the tag did fire a 'newintent' event, but onNdefDiscovered, onTagDiscovered and onTechDiscovered never caught it, even though my intentFilters never changed. Catching the intents outside of foreground dispatch worked as expected.

Trying multiple combinations of different Titanium SDKs and ti.nfc versions didn't seem to help, so I can't be certain what changed or when. BUT I did find a potential fix here: https://stackoverflow.com/questions/76655730/why-nfc-works-with-pendingintent-flag-mutable-and-not-with-pendingintent-flag-im

Changing the createPendingIntent() in NfcForegroundDispatchFilter's to be FLAG_MUTABLE instead of FLAG_IMMUTABLE, with no other changes, solved my problem and I can read NDEF tags again. The e.intent now looks like:

[INFO] Intent {
[INFO] url: undefined,
[INFO] type: 'text/plain',
[INFO] packageName: 'com.something.something',
[INFO] className: 'org.appcelerator.titanium.TiActivity',
[INFO] action: 'android.nfc.action.NDEF_DISCOVERED',
[INFO] flags: 805306368,
[INFO] data: null,
[INFO] _hasJavaListener: undefined,
[INFO] apiName: 'Ti.Android.Intent',
[INFO] bubbleParent: true
[INFO] }

To be honest, this is a little over my head and I'm not sure if this is the best fix. If anyone is interested, my super minor edit can be found in pull request #79

Hi,

i can't to discovery a void tag (a new tag without record text). Could the problem be the mimetype? i search text/plain, but there isn't a text on a new tag.
I try a Tagview ad foreground.

In the first case (Tagview) I can only find a tag if it is written, in the second case (foreground) I can't find out anything.

can someone help me?

thanks
bye

I'm porting my app from SDK 6.x to the lastest 7.x but I've encountered some problems, the app doesn't start anymore and after removing all modules and re-adding one at time I figured that ti.nfc is the problem.
The log is this one:
-- Start application log ----------------------------------------------------- [INFO] : TiApplication: (main) [0,0] checkpoint, app created. [INFO] : TiApplication: (main) [90,90] Titanium 7.1.1 (2018/04/19 11:11 undefined) [INFO] : MultiDex: VM with version 2.1.0 has multidex support [INFO] : MultiDex: install [INFO] : MultiDex: VM has multidex support, MultiDex support library is disabled.

The last 3 lines of WARN blocks everything and crash the app.

I am trying to write chips but these are android.nfc.tech.NdefFormatable and not android.nfc.tech.Ndef and for this reason when I do the technology validation with the method tech.isValid() this returns error

Hi,

I have followed and read all the instructions. I am able to run the app in iOS and able to start the scanning. App scans the tag but when I try to read the scanned information then it shows no records on iOS - {
[INFO] : messages = (
[INFO] : {
[INFO] : }
[INFO] : );
[INFO] : }

But on android its working fine and shows the records. I tried other nfc apps on the same iPhone 7 iOS 13.3 and its reading and showing records.

What should be the problem here?

Hi,

there is a way to write NFC tags on iOS?

thanks

I am trying to use the module, enabled NFC in identified, with new provision profile and running on iPhone XS but getting error

Hi, I just updated to XCode 10 and I cannot build the app with the ti.nfc module.

If I remove the <module platform="iphone">ti.nfc</module> from tiapp.xml it compiles as always.

Running the stock TagForeground example on both 7.0.1 and 7.1.0 results in:

Can anyone help with reading UID from tag that seemed to function until iOS 13?
