Error: PlatformException(no_fragment_activity, local_auth plugin requires activity to be a FragmentActivity., null) - erinnaph - 07-21-2023
Getting this error while using local_auth version 0.6.0
It's working fine for iOS but getting this error in android.
Already have implemented ```class MainActivity: FlutterFragmentActivity()``` but still getting this issue
RE: Error: PlatformException(no_fragment_activity, local_auth plugin requires activity to be a FragmentActivity., null) - verifiers745373 - 07-21-2023
change your main activity to override FlutterFragmentActivity
import android.os.Bundle
import io.flutter.app.FlutterFragmentActivity
import io.flutter.plugins.GeneratedPluginRegistrant
class MainActivity: FlutterFragmentActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
GeneratedPluginRegistrant.registerWith(this)
}
}
if you are using flutter embedding version 2
import androidx.annotation.NonNull
import io.flutter.embedding.engine.FlutterEngine
import io.flutter.embedding.android.FlutterFragmentActivity
import io.flutter.plugins.GeneratedPluginRegistrant
class MainActivity: FlutterFragmentActivity() {
override fun configureFlutterEngine(@NonNull flutterEngine:
FlutterEngine) {
GeneratedPluginRegistrant.registerWith(flutterEngine)
}
}
RE: Error: PlatformException(no_fragment_activity, local_auth plugin requires activity to be a FragmentActivity., null) - Mrformatives351 - 07-21-2023
I am using local_auth 0.6.2+3
My MainActivity.kt
package xx.xx.xxx
import androidx.annotation.NonNull;
import io.flutter.embedding.android.FlutterFragmentActivity
import io.flutter.embedding.engine.FlutterEngine
import io.flutter.plugins.GeneratedPluginRegistrant
class MainActivity: FlutterFragmentActivity() {
override fun configureFlutterEngine(@NonNull flutterEngine: FlutterEngine) {
GeneratedPluginRegistrant.registerWith(flutterEngine);
}
}
I was using SplashScreenUntilFirstFrame meta tag, Removing it from my main/AndroidManifest.xml works absolutely fine now.
<meta-data
android:name="io.flutter.app.android.SplashScreenUntilFirstFrame"
android:value="true"/>

2nd answer worked fine if we remove **@NotNull** like
import androidx.annotation.NonNull
import io.flutter.embedding.engine.FlutterEngine
import io.flutter.embedding.android.FlutterFragmentActivity
import io.flutter.plugins.GeneratedPluginRegistrant
class MainActivity: FlutterFragmentActivity() {
override fun configureFlutterEngine( flutterEngine:
FlutterEngine) {
GeneratedPluginRegistrant.registerWith(flutterEngine)
}
}

Add the following line to the dependencies in your app level `build.gradle` file:
dependencies{
api "androidx.core:core:1.1.0-aplha03"
}

Flutter details
Flutter version 1.22.4 at /Users/macbookpro/Desktop/development/flutter
- Framework revision 1aafb3a8b9 (4 weeks ago), 2020-11-13 09:59:28 -0800
- Engine revision 2c956a31c0
- Dart version 2.10.4
- local_auth: ^0.6.3+4
If you are using java then change your main activity to this
import androidx.annotation.NonNull;
import io.flutter.embedding.engine.FlutterEngine;
import io.flutter.embedding.android.FlutterFragmentActivity;
import io.flutter.plugins.GeneratedPluginRegistrant;
import io.flutter.embedding.android.FlutterActivity;
public class MainActivity extends FlutterFragmentActivity{
}
RE: Error: PlatformException(no_fragment_activity, local_auth plugin requires activity to be a FragmentActivity., null) - courtnayl - 07-21-2023
In my case, i forgot to change in AndroidManifest.xml file.
Complete changes for reference
MainActivity.java
import android.os.Bundle;
import io.flutter.app.FlutterFragmentActivity;
import io.flutter.plugins.flutter_plugin_android_lifecycle.FlutterAndroidLifecyclePlugin;
import io.flutter.plugins.localauth.LocalAuthPlugin;
public class MainActivity extends FlutterFragmentActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
FlutterAndroidLifecyclePlugin.registerWith(
registrarFor(
"io.flutter.plugins.flutter_plugin_android_lifecycle.FlutterAndroidLifecyclePlugin"));
LocalAuthPlugin.registerWith(registrarFor("io.flutter.plugins.localauth.LocalAuthPlugin"));
}
}
Then
AndroidManifest.xml
From
<application
android:label="<name>"
android:icon="@mipmap/ic_launcher">
<activity
android:name="io.flutter.embedding.android.FlutterActivity"
....
To
<application
android:label="<name>"
android:icon="@mipmap/ic_launcher">
<activity
android:name="io.flutter.embedding.android.FlutterFragmentActivity"
....

This is what I did to solve this issue.
Change your `MainActivity.kt` as below:
```
package com.[your.package]
import androidx.annotation.NonNull
import io.flutter.embedding.android.FlutterFragmentActivity
import io.flutter.embedding.engine.FlutterEngine
import io.flutter.plugins.GeneratedPluginRegistrant
class MainActivity: FlutterFragmentActivity() {
override fun configureFlutterEngine(@NonNull flutterEngine: FlutterEngine) {
GeneratedPluginRegistrant.registerWith(flutterEngine)
}
}
```
However, after changing this `MainActivity.kt`, I also faced some other issue with the `Theme.AppCompat`. Check this out for the solution.
RE: Error: PlatformException(no_fragment_activity, local_auth plugin requires activity to be a FragmentActivity., null) - fastmeridbnpbs - 07-21-2023
I tried adding the code in MainActivity.kt. For some reason, it doesn't take the code from MainActivity.kt and only searches for MainActivity.java. So the following code in MainActivity.java fixed the issue for me.
MainActivity.java
package com.<package_name>;
import android.os.Bundle;
import io.flutter.embedding.android.FlutterFragmentActivity;
import androidx.annotation.NonNull;
import io.flutter.embedding.engine.FlutterEngine;
import io.flutter.plugins.GeneratedPluginRegistrant;
import io.flutter.plugins.flutter_plugin_android_lifecycle.FlutterAndroidLifecyclePlugin;
import io.flutter.plugins.localauth.LocalAuthPlugin;
public class MainActivity extends FlutterFragmentActivity {
public void configureFlutterEngine(@NonNull FlutterEngine flutterEngine)
{
GeneratedPluginRegistrant.registerWith(flutterEngine);
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
}

From the docs -https://pub.dev/documentation/local_auth/latest/
Simply use the code below in your MainActivity.kt
package [package ID here]
import io.flutter.embedding.android.FlutterFragmentActivity
class MainActivity: FlutterFragmentActivity() {
}
Uninstall your current build of the app and then rebuild again
By the way, ensure you're not making multiple calls for
auth.authenticate(...)
