问题描述

我正在尝试使用local_auth，将其从0.4.0更新到0.6.2

I'm trying to work with local_auth, updating from 0.4.0 to 0.6.2

我按照说明进行操作，将MainActivity.java中的FlutterActivity更改为FlutterFragmentActivity

I followed the instructions, changing the FlutterActivity to FlutterFragmentActivity in my MainActivity.java

(根据本指南 https://github.com/flutter/flutter/wiki/Upgrading-pre-1.12-Android-projects 并使用此线程

( according with this guide https://github.com/flutter/flutter/wiki/Upgrading-pre-1.12-Android-projects and with this thread https://github.com/flutter/flutter/issues/57678)

通过这种方式

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

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

我也更改了style.xml

I also changed my style.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="LaunchTheme" parent="Theme.AppCompat.NoActionBar">
        <item name="android:windowBackground">@drawable/launch_background</item>
    </style>
</resources>

和我的AndroidManifest.xml

and my AndroidManifest.xml

<application
        android:icon="@mipmap/ic_launcher"
        android:allowBackup="false"
        android:fullBackupContent="false"
        android:label="XXX">
        <activity
            android:name=".MainActivity"
            android:configChanges="orientation|keyboardHidden|keyboard|screenSize|locale|layoutDirection|fontScale|screenLayout|density"
            android:hardwareAccelerated="true"
            android:launchMode="singleTop"
            android:theme="@style/LaunchTheme"
            android:windowSoftInputMode="adjustResize">
            <!-- This keeps the window background of the activity showing
                 until Flutter renders its first frame. It can be removed if
                 there is no splash screen (such as the default splash screen
                 defined in @style/LaunchTheme). -->

            <meta-data
                android:name="io.flutter.embedding.android.SplashScreenDrawable"
                android:resource="@drawable/launch_background" />

            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>
                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
            <intent-filter>
                <action android:name="FLUTTER_NOTIFICATION_CLICK"/>
                <category android:name="android.intent.category.DEFAULT"/>
            </intent-filter>
        </activity>
        <activity android:name="com.apptreesoftware.barcodescan.BarcodeScannerActivity"/>

        <provider
            android:name="vn.hunghd.flutterdownloader.DownloadedFileProvider"
            android:authorities="${applicationId}.flutter_downloader.provider"
            android:exported="false"
            android:grantUriPermissions="true">
            <meta-data
                android:name="android.support.FILE_PROVIDER_PATHS"
                android:resource="@xml/provider_paths"/>
        </provider>
        <meta-data
            android:name="flutterEmbedding"
            android:value="2" />
    </application>
</manifest>

它适用于Android 28及更高版本，但不适用于旧版本.

It works on Android 28 and higher, but not on older versions.

当我在android 27上运行时，出现此错误

When I run on android 27 I got this error
