To read NFC data in an Android app, you would typically rely on the Android NFC API. You might need to use traditional Android views and integrate them with Jetpack Compose if direct Jetpack Compose support is not available. Here's a basic outline of how you might integrate NFC reading in an Android app that uses Jetpack Compose: Add NFC Permission: Ensure that you have the necessary permissions in your AndroidManifest.xml file. xml <uses-permission android:name="android.permission.NFC" /> Handle NFC Intent: In your activity or fragment, handle the NFC intent in the onCreate or onNewIntent method. kotlin class YourActivity : AppCompatActivity() { override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) setContent { YourComposeContent() } handleNfcIntent(intent) } override fun onNewIntent(intent: Intent?) { super.onNewIntent(intent) handleNfcIntent(intent) } private fun handleNfcIntent(intent: Intent?) { if (NfcAdapter.ACTION_NDEF_DISCOVERED == intent?.action) { val rawMessages = intent.getParcelableArrayExtra(NfcAdapter.EXTRA_NDEF_MESSAGES) // Handle the NFC data here } } } Check NFC Availability: Before trying to read NFC data, check if NFC is available on the device. kotlin val nfcAdapter = NfcAdapter.getDefaultAdapter(this) if (nfcAdapter == null) { // NFC is not supported on this device } else { // NFC is supported, set up NFC reading } Declare Intent Filter: In your manifest, declare an intent filter for the activity or service that should handle NFC data. xml <intent-filter> <action android:name="android.nfc.action.NDEF_DISCOVERED" /> <category android:name="android.intent.category.DEFAULT" /> <data android:mimeType="application/com.yourapp" /> </intent-filter> Modify the mimeType attribute to match the type of data you expect from NFC. Please check the official Android documentation and Jetpack Compose documentation for any updates or changes after my last knowledge update. Always use the latest versions of libraries and tools to benefit from improvements and bug fixes.
