+# FIN65 - Patch Android biométrie
+
+Ce patch prépare Android pour `local_auth`.
+
+Il fait :
+- ajoute `android.permission.USE_BIOMETRIC` dans `AndroidManifest.xml` ;
+- garde `android.permission.INTERNET` ;
+- garde `android:usesCleartextTraffic="true"` ;
+- force le label `FIN65` ;
+- modifie `MainActivity` pour hériter de `FlutterFragmentActivity` ;
+- tente de mettre `minSdk` à 24 si nécessaire ;
+- lance `flutter clean` et `flutter pub get`.
+
+## Utilisation
+
+Depuis ce dossier :
+
+```powershell
+.\apply_android_biometrics_patch.bat
+```
+
+Puis :
+
+```powershell
+cd D:\07-Logiciels\20-FIN65\fin65_mobile
+flutter run
+```
+
+Des sauvegardes `.before_biometric_*.bak` sont créées avant modification.
