local_auth: ^0.6.0+1 works fail

[suchul]

It works well in older versions(0.4.1) but it doesn't work in newer versions

 bool isAuthorized = false;
      try {
        isAuthorized = await _localAuthentication.authenticateWithBiometrics(
          localizedReason: "test",
          useErrorDialogs: true,
          stickyAuth: true,
        );
      } on PlatformException catch (e) {
        print(e);
      }

print(e);
PlatformException(no_fragment_activity, local_auth plugin requires activity to be a FragmentActivity., null)

Hi @suchul
could you please provide your flutter doctor -v
and your flutter run --verbose?
Also, to better address the issue, would be helpful
if you could post a minimal code sample to reproduce the problem
Thank you

Hi Francecsco lapida Thank you for your support I will send you a sample app for this issue pubspec.yml ==> local_auth: ^0.6.0+1 if you run this app, you can see the problem And pubspec.yml ==> local_auth: ^0.4.0+1. if you modify the code and run it, it works fine. this app was created as a flutter application Please check you this issue Thanks sckang test_local_auth.zip <https://drive.google.com/file/d/1VLvcwQXfxKTQuShV_jWxVjCx9Oy-vt3J/view?usp=drive_web> 2019년 11월 20일 (수) 오후 7:20, Francecsco Iapicca <[email protected]>님이 작성:

base on the error you have to change your MainActivity

public class MainActivity extends FlutterActivity {
  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    GeneratedPluginRegistrant.registerWith(this);
  }
}

to

public class MainActivity extends FlutterFragmentActivity {
  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    GeneratedPluginRegistrant.registerWith(this);
  }
}

Thanks for your contribution.
Could everyone who still has this problem please file a new issue with the exact descriptions what happens, logs and the output of 'flutter doctor -v' please.
All system setups can be slightly different so its always better to open new issues and reference related issues.

@VladyslavBondarenko Any help from your side. could you please look inti it once.

[siva563]

@dnfield Could you please look into it above issue.

[VladyslavBondarenko]

@suchul
Mentioned code - java-code, wasn't you proposed to convert it to kotlin?

This main file in kotlin should look like:

package com.example.yourpackagename

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)
    }
}

[siva563]

@VladyslavBondarenko where should add this code I mean Which file? I am not able to find any MainActivity.Java file

[VladyslavBondarenko]

@suchul
In your app\src\main\kotlin\com\example\ntta_mobile_app\MainActivity.kt

[VladyslavBondarenko]

@suchul
Also if you have Type mismatch: required PluginRegistry, Found: MainActivity on registerWith(this), try firebase/flutterfire#1684 (comment)

[dnfield]

I think @mklim @matthew-carroll or @blasten would know what's going on better here

[matthew-carroll]

I've read through this read but it's not clear to me if a problem still exists, and if it does, what the particular problem is. There was a recommendation to change from FlutterActivity to FlutterFragmentActivity. Did that solve the original problem in this issue? Most of the comments after that appear to be confusion around Java vs Kotlin implementations...

[just1random]

I just created a new project using -a java flag (cause I don't want kotlin).
Here's the default MainActivity.java:

package com.example.tired;

import androidx.annotation.NonNull;
import io.flutter.embedding.android.FlutterActivity;
import io.flutter.embedding.engine.FlutterEngine;
import io.flutter.plugins.GeneratedPluginRegistrant;

public class MainActivity extends FlutterActivity {
  @Override
  public void configureFlutterEngine(@NonNull FlutterEngine flutterEngine) {
    GeneratedPluginRegistrant.registerWith(flutterEngine);
  }
}

I can't make this work by importing import io.flutter.app.FlutterFragmentActivity And changing FlutterActivity to FlutterFragmentActivity. In total i can't make this work with a brand new project. Example repo has a different MainActivity.java and it does'nt work. Here's example repo MainActivity.java:

package io.flutter.plugins.localauthexample;

import io.flutter.embedding.android.FlutterFragmentActivity;
import io.flutter.embedding.engine.FlutterEngine;
import io.flutter.plugins.localauth.LocalAuthPlugin;

public class MainActivity extends FlutterFragmentActivity {
  // TODO(bparrishMines): Remove this once v2 of GeneratedPluginRegistrant rolls to stable. https://github.com/flutter/flutter/issues/42694
  @Override
  public void configureFlutterEngine(FlutterEngine flutterEngine) {
    flutterEngine.getPlugins().add(new LocalAuthPlugin());
  }
}

Edit: Got it working by the following MainActivity.java:

import io.flutter.embedding.android.FlutterFragmentActivity;
import io.flutter.embedding.engine.FlutterEngine;
import io.flutter.plugins.GeneratedPluginRegistrant;

import android.os.Build;
import android.view.ViewTreeObserver;
import android.view.WindowManager;

public class MainActivity extends FlutterFragmentActivity {
  @Override
  public void configureFlutterEngine(@NonNull FlutterEngine flutterEngine) {
    GeneratedPluginRegistrant.registerWith(flutterEngine);
  }
}

Edit: Got it working by the following MainActivity.java:

import io.flutter.embedding.android.FlutterFragmentActivity;
import io.flutter.embedding.engine.FlutterEngine;
import io.flutter.plugins.GeneratedPluginRegistrant;

import android.os.Build;
import android.view.ViewTreeObserver;
import android.view.WindowManager;

public class MainActivity extends FlutterFragmentActivity {
  @Override
  public void configureFlutterEngine(@NonNull FlutterEngine flutterEngine) {
    GeneratedPluginRegistrant.registerWith(flutterEngine);
  }
}

Same for Kotlin :

import io.flutter.embedding.android.FlutterFragmentActivity;
import io.flutter.embedding.engine.FlutterEngine;

import io.flutter.plugins.GeneratedPluginRegistrant

import android.os.Build;
import android.view.ViewTreeObserver;
import android.view.WindowManager;

class MainActivity : FlutterFragmentActivity() {
   override fun configureFlutterEngine(@NonNull flutterEngine: FlutterEngine) {
       GeneratedPluginRegistrant.registerWith(flutterEngine)
   }
}
