How to add fragment activity to MainActivity.java or MainAcyivity.kt
问题
I am trying to build fingerprint feature in my Flutter apps and I am using local_auth package... the problem is that I always get the following error-
PlatformException(no_fragment_activity, local_auth plugin requires activity to be a FragmentActivity., null)
I try to add FragmentActivity to MainActivity.kt but it doesn't work.. here is the structure of my folder... so should I create MainActivity.java? and where should I place MainActivity.java in my folder?
and here is the content of my MainActivity.kt
package com.projectimport androidx.annotation.NonNull;import io.flutter.embedding.android.FlutterActivityimport io.flutter.embedding.engine.FlutterEngineimport io.flutter.plugins.GeneratedPluginRegistrantclass MainActivity: FlutterActivity() {override fun configureFlutterEngine(@NonNull flutterEngine: FlutterEngine) {GeneratedPluginRegistrant.registerWith(flutterEngine);}}

这是如何使用Kotlin实现的：
import androidx.annotation.NonNullimport io.flutter.embedding.android.FlutterFragmentActivityimport io.flutter.embedding.android.FlutterActivityimport io.flutter.embedding.engine.FlutterEngineimport io.flutter.plugins.GeneratedPluginRegistrantimport android.os.Buildimport android.view.WindowManagerimport android.view.ViewTreeObserverclass MainActivity: FlutterFragmentActivity() {override fun configureFlutterEngine(@NonNull flutterEngine: FlutterEngine) {GeneratedPluginRegistrant.registerWith(flutterEngine)}}
