NFC doesn't work in the APK | Tauri Apps | Page 1

I made a app with NFC plugin on Tauri mobile. In the development environment, NFC reading and writing worked fine, but when I installed the APK after building the app, it doesn't work. Does anyone have any ideas to solve this problem?

This is the only error I see when trying to use NFC

         E  win=Window{cc6012f u0 com.example.app/com.example.app.MainActivity} destroySurfaces: appStopped=true cleanupOnResume=false win.mWindowRemovalAllowed=false win.mRemoveOnExit=false win.mViewVisibility=8 caller=com.android.server.wm.ActivityRecord.destroySurfaces:6539 com.android.server.wm.ActivityRecord.destroySurfaces:6520 com.android.server.wm.ActivityRecord.notifyAppStopped:6584 com.android.server.wm.ActivityRecord.activityStopped:7172 com.android.server.wm.ActivityClientController.activityStopped:258 android.app.IActivityClientController$Stub.onTransact:613 com.android.server.wm.ActivityClientController.onTransact:136 ```

I've been trying various methods for hours but none of it worked

#

I think I'm thinking about something wrong but I don't know what is..

Disclaimer that I've never dealt with this before, but are the permissions set up correctly as per: https://developer.android.com/develop/connectivity/nfc/nfc#manifest ?

I've already tried it but it does't work

#

#

also even if I don't add it to the manifest, it already shows the permission for NFC

#

maybe it's not completely unrelated

#

added this lines:

  <uses-permission android:name="android.permission.NFC"/>
  <uses-feature android:name="android.hardware.nfc" android:required="true"/>

And add this in proguard-rules.pro

-keep class app.tauri.nfc.** { *; }

#

Solved ✅

#

it takes 16hour

#

maybe proguard broke invoke?

I tried some cases. The result is I don't need to add NFC permission in manifest, Tauri do that. Just add -keep class app.tauri.nfc.** { *; } in progaurd-rules.pro. Maybe progaurd broke invoke?

Interesting. I'm not too familiar with any of that so I don't have much to weigh in, but glad you figured it out!

It seems need option for progaurd, just as we can set permissions for Tauri plugins to automatically add to the manifest
